Koh Mak Travel Guide: Best Things to Do, Beaches & Where to Stay

ByKelsey Heinrichs Hours

Thailand’s best-kept secret is Koh Mak, and having recently visited this untouched tropical paradise, I’ll admit that I was (almost) tempted to keep it to myself. But I couldn’t resist putting together a Koh Mak travel guide so others can experience just how special it is.

Located in Trat Province, Koh Mak is a small island that’s perfect for a slow-paced, relaxing beach holiday. With white sandy beaches, great snorkelling, incredible seafood, friendly locals and a strong focus on eco-conscious resorts, Koh Mak is where your days revolve around swimming, cycling and doing very little (without any guilt!).

If you’re reading this, chances are someone has already told you just how amazing Koh Mak is. And because you’re clearly sensible, you’ve either already booked your trip, or you’re deep in the research phase, trying to work out if it’s worth it. Either way, you’re in the right place, because this guide covers everything you need to know before visiting Koh Mak.

Locals often say Koh Mak is what Thailand felt like 20–30 years ago, before mass tourism took over islands like Phuket and Koh Samui. It’s slightly more off the beaten path, which means fewer crowds, quieter beaches and a marine environment that’s been carefully looked after by the local community. That’s the beauty of this island; people who visit Koh Mak feel just as motivated to protect it as the locals who call it home.

Keep reading for everything you need to know about visiting Koh Mak, including how to get there, how to get around, the best things to do and where to eat, stay and drink.

Why Visit Koh Mak?

If you’re dreaming of a tropical getaway that actually feels like a holiday – you know, the kind where you come back feeling relaxed rather than like you’ve just completed a triathlon – then Koh Mak is the destination for you.

While many tourists visiting this part of Thailand head to nearby islands like Koh Chang and Koh Kood, Koh Mak is often overlooked, meaning you can avoid the crowds you’ll find elsewhere.

In fact, during my time on Koh Mak, I only heard a British accent ONCE during my entire trip, and it was a thick Cockney voice loudly declaring: “This is bloody lovely, innit?” while I was walking along a palm-lined beach. And to be fair, he wasn’t wrong!

  • Sandy beach lounge with wooden chairs and bean bags arranged under a fringed umbrella and palm trees beside the ocean. Calm turquoise water stretches behind the seating area with a hammock and string lights adding to the relaxed tropical setting.

Koh Mak is easily one of the quietest and most peaceful places I’ve visited in Thailand. It’s refreshingly calm, especially compared to the chaos of Bangkok. While the capital never sleeps, Koh Mak very much gets its beauty sleep, and it shows in its pristine beaches, clear turquoise water and the general sense that everyone’s in no rush whatsoever.

One of the main reasons Koh Mak has avoided mass tourism is because of the fact that the island is privately owned by a small number of local families, who have intentionally limited large-scale development. As a result, you won’t find high-rise hotels or mega resorts here, just smaller boutique stays, which naturally keeps visitor numbers lower.

  • Woman in a light green dress walks barefoot across white sand toward the ocean, framed by tall palm trees and wooden benches with a few people sitting in the shade. Turquoise water, scattered rocks, and a distant green island sit under a clear blue sky, creating a relaxed tropical beach scene.
  • Aerial view of a quiet tropical beach with clear shallow water along the shore, bordered by a long stretch of pale sand and dense palm trees. A few small huts and scattered people sit beneath the trees, emphasizing the secluded and peaceful coastal setting.

Everyone on Koh Mak seems to know each other, which makes sense given the population is only around 1,000 people. There’s a real community feel, and locals work together to preserve the island’s laid-back atmosphere, something visitors are encouraged to respect too.

Koh Mak is also known for its sustainability efforts. It has been recognised as one of the Top 100 Green Destinations globally and is often referred to as one of Thailand’s leading low-carbon islands. There are various plastic reduction initiatives in place, and visitors can even get involved in local beach clean-ups.

  • Colorful outdoor sign reading "GREEN DESTINATION KOH MAK" decorated with bright patterns, surfboards, and tropical illustrations. Palm trees and ocean views appear behind the sign under a partly cloudy sky.

There’s no party scene on Koh Mak, and you won’t find any full moon raves here either. Nightlife is very much on the tame side, with just a handful of relaxed beach bars. Most places wind down early, with no loud music or noise after 10 pm. Because of this, Koh Mak tends to attract a slightly older, calmer crowd, making it ideal for couples, families or anyone looking to actually switch off.

Another reason Koh Mak still feels relatively untouched is that it’s a little harder to get to than places like Phuket, which has its own international airport. That said, it’s actually much easier to reach than you might expect, with boat transfers from the mainland taking under an hour.

  • Aerial view of a long curved sandy beach bordered by dense palm trees and clear turquoise water. Dark reef patches appear beneath the surface while small boats float offshore and distant islands fade into the horizon.

How to Get to Koh Mak

While Koh Mak gives remote tropical island vibes, it’s actually not too far from the mainland and surprisingly not that difficult to get to compared to other Thailand island hotspots.

Koh Mak is located in the Gulf of Thailand, part of the Trat Province, around 300km from Bangkok and roughly 40-50km from Trat town (the mainland pier area),
 
There’s no airport in Koh Mak, which means the only way to get there is by ferry or speedboat from the mainland.

There are two main options for getting to Koh Mak from Bangkok. I did the first option for convenience; however, I’ve included a second option in case you’re a bit more budget-conscious.

  • Speedboat docked at a small pier beside a sandy beach with shallow clear water in the foreground. A person stands on the pier while a green island rises in the background under a bright blue sky.

Option 1: Fastest Route from Bangkok

Journey time: 4-5 hours

First, you’ll need to fly to Trat Airport (TDX), which is a 1-hour flight from Bangkok Suvarnabhumi Airport (BKK), served by Bangkok Airways.

There are only a handful of flights each day, so aim to land in Trat before around 2 pm to ensure you can catch a boat and arrive on Koh Mak the same day. Flights typically cost around £70–£150 return, depending on the time of year and how far in advance you book.

From Trat Airport, you’ll then need to travel to Laem Ngop Pier (20–30 minute drive) or Laem Sok Pier (1 hour drive). Both piers are where speedboats depart for Koh Mak. I recommend asking your hotel on Koh Mak which pier they recommend you depart from – in fact, most hotels can arrange your boat transfer for you.

Make sure to have your boat transfer booked in advance, as schedules are limited. The boat ride takes 45–60 minutes and usually costs around 450–600 THB (£10–£15).

Option 2: Affordable Route from Bangkok

Journey time: 7-8 hours

The most affordable way to get to Koh Mak from Bangkok starts with a 5–6 hour coach journey to Laem Sok Pier (near Trat) from Bangkok Suvarnabhumi Airport (BKK).

It’s easiest to get a combination ticket, which includes the bus journey from the airport + speedboat to Koh Mak, which can be booked via sites like 12Go Asia for around 1100 THB (£25).

Getting to Koh Mak from Nearby Islands (Koh Kood & Koh Chang)

There are also direct boats from the nearby islands of Koh Kood and Koh Chang, making it really easy to include Koh Mak as part of a Thailand island-hopping itinerary.

From Koh Kood, the journey is quick and straightforward, usually taking around 30–60 minutes, with tickets costing roughly 300–600 THB. There are typically one or two departures per day, often operated by the same companies running mainland routes.

From Koh Chang, you can catch a speedboat from Bang Bao Pier, with the journey taking around 45–90 minutes depending on sea conditions. Tickets are usually priced between 400 and 600 THB, and while services are slightly less frequent than on Koh Kood, it’s still a very easy route.

Just keep in mind that boat schedules can vary depending on the season and weather conditions, so it’s always worth checking times in advance or asking your hotel to help arrange your transfer.

Best Time to Visit Koh Mak

The best time to visit Koh Mak is between November and February, which is Thailand’s dry season. 

Koh Mak is a great winter sun destination, with average temperatures around 28–32°C (83–90°F) during these months, with low rainfall and plenty of clear blue skies.

I visited towards the end of March, which was beautifully sunny; however, a bit too hot and humid for my liking. If I got the chance to go again (because once is not enough!), I’d definitely book my trip for January or February when the weather is more comfortable.

  • Quiet sandy beach lined with tall leaning palm trees casting shadows along the shore. Clear turquoise water gently meets the sand with lush green hills in the distance under a bright sky.

April is one of the hottest months on the island, with temperatures frequently reaching 35–40°C (95–104°F). The sky can also turn slightly hazy during this time due to a mix of humidity and agricultural burning in parts of Thailand.

That said, if you do visit in April, try planning your trip around the Songkran (Thai New Year) festivities, which take place from 13–15 April. Locals celebrate by having water fights in the streets, fully armed with water pistols. It’s a lot of fun and a great way to cool down from the intense heat.

From May onwards, Thailand experiences its wet season, which can last until October. 

Travelling during this time can be a bit of a gamble. While I personally have never travelled to Thailand during the wet season, I know friends who have and got lucky with two weeks of constant sunshine. While others got hit with storms.

Personally, I wouldn’t risk it, especially for a smaller island like Koh Mak, where the weather greatly impacts transport, boat trips and activities more than on bigger islands.

If you want the best chance of perfect island weather, plan your trip to Koh Mak for November to February.

  • Small blue boat with a canopy floats in shallow clear water near the shore, with the words "KOH KHAM" painted on its side. Gentle waves lap at the sandy beach in the foreground while a lush green island stretches across the horizon under a bright blue sky.
  • A narrow dirt road winds through a lush tropical landscape filled with tall palm trees and dense greenery, viewed from above. A single vehicle travels along the path, emphasizing the remote and peaceful jungle setting.

How to Get Around Koh Mak

Within your first hour spent in Koh Mak, you’ll quickly realise just how quiet it is. There’s no obnoxious music blasting from beach clubs, no crowds, no traffic, and, commonly, you can go a whole day without seeing a single car.

So then… how does everyone get around? Because spoiler alert: there is no Uber, Grab, or traditional public transport available on Koh Mak.

While most hotels are either beachfront or only a short walk from the sand, it would still take hours to walk across the island, which stretches 10km at its widest point. I mean, sure, it’s doable… but not exactly enjoyable in the heat.

By Scooter

Most locals and tourists get around by scooter. You can rent a scooter from your hotel or local rental shops for around 250–350 THB per day.

And please don’t forget to wear a helmet at all times. Even though most scooter journeys are only 5-15 minutes across the island, it’s just never worth the risk! 

If you don’t feel comfortable riding a scooter, which I personally don’t, there are plenty of other options for getting around Koh Mak.

  • Three motorbikes parked on grass beneath palm trees in a tropical garden setting. Small bungalow style cottages and lounge chairs sit in the background near a sign that reads "PARKING".

By Cycling

The island is mostly flat, so it’s perfect for cycling. Bikes can be rented from hotels for around 100–200 THB per day, and it’s a really nice way to explore the island at a slower pace.

Try checking out Totti on the main street for scooter & bike rentals.

By Golf Buggy

Another alternative is renting a golf buggy, which some hotels offer, that can sit between 2 and 6 people. These are more expensive, usually around 1000–1,500 THB per day, but a great option if you’re travelling with young kids or, like me, just not keen on scooters.

I recommend booking a golf buggy in advance, as this mode of transport is usually the first to sell out on Koh Mak, with limited buggies available compared to scooters or bicycles.

  • Pink golf cart parked on a paved path near a tropical beach lined with palm trees. A thatched pavilion sits on a grassy hill above while the ocean and a wooden pier stretch into the distance.

By Songtaew

The other most commonly used mode of transport on Koh Mak is a songthaew. This is essentially the island’s taxi service, a shared pickup truck with benches in the back. It’s a great option for evenings when you want to head out for dinner or drinks and not worry about getting back.

Short trips typically cost around 100–300 THB, depending on distance, and you can arrange for a driver to pick you up and take you back to your hotel.

  • Yellow open air taxi truck with bench seating parked on a paved area surrounded by trees. A painted fish decorates the side along with text reading "MR. YAI TAXI SERVICE 087 054 4475 ID LINE" on the door.

During my visit to Koh Mak, I was carted around by the fantastic Mr Yai in his very iconic yellow coloured songthaew, which was covered in a custom mural of a fish.

I highly recommend his service. He was always early, super friendly, and had loads of great local recommendations. You can message him on WhatsApp +660920547275 to check availability, and even if he’s busy, he’ll usually pass you on to another driver. Everyone seems to know everyone on the island, which makes things very easy.

You can find a list of other drivers and their phone numbers at kohmaknews.com/koh-mak-taxis.

It’s also worth joining the Facebook group, Koh Mak Connect – it’s the easiest way to be connected to local drivers, get recommendations and find places to rent scooters & bicycles from.

Beaches in Koh Mak

One of the things I loved the most about Koh Mak (and believe me when I say there was quite an extensive list of things I loved!) is that the best beaches were free to visit. Often, what happens on other islands is that beaches are roped off by fancy resorts – but not on Koh Mak!

The two main beaches on Koh Mak are Ao Suan Yai and Ao Kao, which is where you’ll spend most of your time. For a longer visit to Koh Mak, there are a few other beaches you can visit, including Laem Son Beach in the Northeast, Ao Pra Beach and Ao Tan Beach (where the Cinnamon Boardwalk is located).

  • Quiet sandy beach lined with tall leaning palm trees casting shadows along the shore. Clear turquoise water gently meets the sand with lush green hills in the distance under a bright sky.
  • Person sitting on a rope swing hanging from a tall palm tree beside a quiet sandy beach. Calm turquoise water and distant islands create a peaceful tropical backdrop.

The best beach on Koh Mak is Ao Suan Yai, which stretches for almost 2 kilometres (roughly 1.2 miles) along the northwest coast. Ao Suan Yai has beautiful white sand, coconut tree-lined sections and shallow teal water with a few beach bars dotted about. While it’s the most popular beach on Koh Mak, there are still plenty of spots to park up with hardly anyone around – even during peak season.

It’s the best beach to watch the sunset with views of Kho Khaam in the distance. I recommend heading to Thai Sabai for golden hour – this beach restaurant serves amazing Thai dishes and cocktails, and they have bean bags here you can sink into and enjoy the views.

  • Open air beachfront restaurant with wooden tables and chairs set on sand beneath a thatched roof decorated with string lights and red bows. Palm trees frame the space while the ocean and anchored boats sit just beyond the seating area.

While Ao Suan Yai is a must-visit, my favourite beach was Ao Kao (Ao Khao). This beach can be accessed via various resorts, restaurants or beach bars. It stretches for nearly 5km, so depending on where you access the beach, you can have a different experience.

I went to Ao Kao multiple times on my trip via the White Sand Beach Resort, and each time I had a small stretch of beach to myself and my top pick of sun lounges or hammocks to laze on. It’s a beautiful golden sand beach, and I’ve probably unconsciously given it top marks because there was an adorable puppy who came for cuddles each time I visited.

  • Quiet sandy beach lined with leaning palm trees and gentle waves along the shoreline. Clear blue water stretches to the horizon under a soft sky, creating a calm tropical atmosphere.

Best Things to Do in Koh Mak

Chill at Cha Cha Beach Club

This was the first place I visited in Koh Mak, and it couldn’t have been a better introduction to the island. I arrived late morning at Koh Mak and my hotel wasn’t ready for check-in yet, so I parked up at Cha Cha Beach Club, located on Ao Tan Beach and just a quick 10-minute journey from Koh Mak’s main pier, Ao Nid.

  • Sandy tropical beach with a hammock strung between palm trees facing calm turquoise water. Colorful flags line the shore while inflatable rings rest on the sand under a bright blue sky.

I honestly couldn’t have dreamed of a more perfect setting. There’s a glorious white sandy beach, bean bags and hammocks to sink into, palm trees swaying in the breeze, and a few adorable dogs dozing in the shade.

Oh, and it’s a completely kid-free zone, so you’re guaranteed a peaceful, chilled atmosphere.

  • Sandy beach seating area with wooden lounge chairs and bean bags arranged around a fringed umbrella near the ocean. A cream wall with string lights and a sign reading "SHELL YEAH" sits behind tropical plants and palms.

I ended up spending a few hours here, sipping cocktails and soaking up the views. I had lunch here too, ordering the massaman beef tacos, which were delicious. That said, I slightly regret not trying their signature Pad Krapao Philly cheesesteak sandwich, which all the reviews rave about. Oh well, there’s always a next time (which I am fully manifesting).

  • Beach bar with a wooden counter and woven chairs set on sand beneath a ceiling of bamboo sticks. A bartender prepares drinks beside bottles and fresh fruit while a warm backlit shelf with seashell decor glows against a neutral wall.
  • Plate of tacos topped with shredded cabbage and red chili slices served with a side of fresh greens and dipping sauce on a pastel table. A glass of iced herbal drink with lemon and rosemary sits nearby on a wooden coaster beside woven chairs.

Mains and cocktails are priced around 250 THB each. Cha Cha Beach Club is open 9 am – 10 pm every day except for Mondays when it’s closed. 2 for 1 drinks are available during Happy Hour between 4.30 pm and 6 pm each day.

Snorkelling Trip to Mu Ko Chang National Park

Snorkelling is one of the best things to do in Koh Mak, thanks to the island’s coral conservation efforts, calm waters, and thriving marine life.

Most visitors tend to snorkel at their hotel or resort, as many have easy swim access to colourful coral patches in shallow water.

For a more special experience, I highly recommend booking a snorkelling boat trip to the nearby Mu Ko Chang National Park. The park covers over 50 protected islands, helping to preserve the area’s marine ecosystems.

  • View from the front of a boat looking out over clear turquoise water toward a rocky island with scattered trees. A few people snorkel near the rocks while another boat floats in the distance under a bright blue sky.

This was one of my favourite activities that I did in Koh Mak! We departed from Ao Nid Pier, and after a 20-minute scenic boat ride, we arrived at our first stop: Big Giant Island (Koh Yak Yai), the first of three islands you’ll visit on this trip.

We spent the most time here as it’s the best spot for snorkelling, followed by Small Giant Island (Koh Yak Lek) and Mabring Island. I could’ve spent all day snorkelling, I was completely mesmerised by the colourful coral and incredible marine life.

  • Underwater view of a coral reef with striped tropical fish swimming around large rocks in clear blue water. Sunlight filters through the surface creating shimmering patterns across the coral and sea floor.

If you book a half-day trip, it usually includes lunch served on San Jhao Beach, where you’ll find beautiful white sand stretches and unique black volcanic rocks dotted along the shoreline, surrounded by crystal-clear blue water.

The boat trip costs around 1,200 THB per person, which includes the national park entrance fee, snorkelling equipment, lunch, fruit, and water, as well as hotel pick-up and drop-off in Koh Mak. Just remember to bring a towel, sunscreen, and a change of clothes. You can book this activity through Koh Mak Divers.

  • Wide sandy beach lined with lush green trees and shade, with people walking and relaxing along the shore. Speedboats are docked in clear turquoise water near a forested hillside under a bright blue sky.

If you have a diving licence, you can also opt for a two-dive trip (around 3,500 THB), or if you’re not certified, a discovery dive with an instructor is available for approximately 4,500 THB.

Just note that drones are strictly forbidden in the national park, but feel free to go all out with photos and videos, I definitely did! I used my DJI Action Pro to capture all of my underwater content.

Cooking Class at Smile Koh Mak

If you’re the kind of person who would happily travel to Thailand just to eat Thai food (because SAME), then you absolutely need to try a Thai cooking class on Koh Mak.

I joined a class at Smile Koh Mak Cooking School, which is set in a beautiful, laid-back spot right by the sea. Our instructor, Leng, was incredibly friendly and guided us through making four different Thai dishes from scratch.

  • Plate of stir fried noodles with tofu, bean sprouts, green onions, and a lime wedge served with chopsticks. Small bowls of condiments and lime sit on a leaf shaped dish beside the meal on a patterned table.

Leng told us that around 60% of the ingredients used in the class come from her own garden, and the prawns we cooked had been delivered by a local fisherman that very morning. It literally doesn’t get much fresher than that!

Leng talked us through each ingredient and technique, explaining how everything comes together, from making curry pastes to balancing flavours in sauces. We started with Pad Thai, which I was slightly humbled to see cooked in about three minutes (clearly, I’ve been doing something very wrong at home). We then made Tom Yum soup, fried tofu, and finished with one of Thailand’s most popular desserts, mango sticky rice.

  • Hand reaching for small bowls of ingredients arranged on a tray lined with a banana leaf, including chopped herbs, dried shrimp, chili flakes, and crushed peanuts. Fresh green onions, tofu, egg, lime wedges, and noodles are laid out for preparing a stir fried noodle dish.
  • Egg cooking in a hot wok over a blue gas flame as a hand uses a spatula to fold it together with shrimp and diced ingredients. The scene captures the start of stir frying noodles with fresh ingredients visible nearby.

I learnt so many new skills that I can’t wait to try them out at home. At the end of the class, Elaine very kindly gifted me a branded apron and a personal recipe book filled with her favourite Thai recipes, which was such a lovely keepsake.

As the classes are small, you can usually request which dishes you’d like to cook in advance. Classes run in the morning between 10 am and 2 pm and again in the evening from 3 pm to 7 pm. Arrive hungry because you’ll of course get to eat all your creations! Classes cost 1500 THB per person and can be booked online at smilekohmak.com.

  • Hands whisking beaten egg in a small glass bowl beside fresh noodles, bean sprouts, and chopped greens on a wooden board. A person wearing a blue apron prepares ingredients for a stir fried noodle dish on a patterned table.
  • Plate of stir fried noodles with shrimp, bean sprouts, and lime served with chopsticks on a patterned table. Fresh herbs, vegetables, and spices are arranged in trays nearby with a glass of dark drink completing the meal setup.

Grab a Cocktail at Blue Pearl Bar

For sea views and an ice-cold cocktail, there’s truly no better place to be on Koh Mak than Blue Pearl Bar. Uniquely positioned at the end of a long pier just off the shore from Cococape Resort, it feels like you’re floating right out over the ocean.

There’s a small fee of 200 THB to access the pier, but this includes a soft drink from the bar, so it’s still absolutely worth it. Make sure you wear your bikini, as you can swim and snorkel directly off the pier.

  • Long wooden pier stretching over clear turquoise water toward a small thatched roof bar on stilts. A sailboat floats nearby and green islands sit on the horizon under a bright blue sky.

It can get pretty stifling hot in the middle of the day with limited shade, so I’d recommend visiting later in the afternoon. Around 5 pm is perfect, when things start to cool down, and you’ll have front row seats for sunset.

Cocktails are around 280 THB each, and I’d definitely recommend trying their signature Cococape Punch, which was as strong as it is delicious.

The Blue Pearl Bar is open from 10 am – 9 pm daily.

  • Thatched roof beach bar on wooden stilts over clear water with a bamboo counter and stools along the edge. Two staff stand behind the bar beneath a sign reading "Blue Pearl Bar" with fresh fruit and drinks displayed.
  • Hand holding a cocktail in a stemmed glass garnished with an orange slice in front of a thatched beach bar over clear water. The bar with stools and fruit display sits in the background while a boat floats on the calm sea.

Half-day Trip to Koh Kham

Koh Kham is a tiny island located just off Koh Mak. In fact, it’s so close it almost feels like part of Koh Mak, sitting only 1km from Ao Suan Yai Beach.

There are two ways to get there. The first, and the easiest, is by small boat, which is what I did. Tickets cost 350 THB per person and can be purchased from the Koh Mak Information Point office.

  • Aerial view of a small tropical island with white sand beaches and lush green trees surrounded by clear turquoise water. A long wooden pier extends into the sea while distant islands fade into the horizon.

There’s no need to book in advance, boats run multiple times per hour between 9 am and 3 pm, and the journey takes just 10 minutes. The price also includes an ice-cold soft drink, which you can collect from the beach shack when you arrive.

The second option is to simply kayak across. This takes around 30 minutes (without breaks), and kayaks can be rented for approximately 150 THB.

  • View from the front of a small boat approaching a lush green island with palm trees along the shoreline. Clear turquoise water surrounds the island under a bright blue sky.
  • White sand beach lined with palm trees and clear turquoise water gently meeting the shore. A blue kayak rests on the sand while a few people walk along the coastline under a bright blue sky.

So, what is there to do on such a tiny island? Honestly… not much, other than relaxing and enjoying the sheer beauty of this little slice of paradise. Walk along the powdery white sand beaches, take a dip in the crystal-clear turquoise water, take a nap under the shade of a palm tree and grab a fresh coconut drink from the beach shack.

There are no proper restaurants, hotels or bars on the island, so I noticed quite a few people bringing picnics with them. There are plenty of benches, seating areas, and sun loungers available to use, all free of charge – thank god this isn’t the Mediterranean.

There are also toilets and shower facilities, but I’d recommend bringing tissues with you as there wasn’t any toilet paper when I visited.

It’s very easy to lose track of time on Koh Kham, but don’t forget the last boat back to Koh Mak departs at 4:30 pm each day. Don’t worry, the locals on the island will make sure no one gets left behind.

  • Beachside wooden hut with a corrugated metal roof and a row of surfboards leaning against the wall on sandy ground. Tall palm trees frame the scene with clear turquoise water and a distant pier visible in the background.

Lunch at Koh Mak Seafood

Set on a jetty overlooking the sea, Koh Mak Seafood is worth visiting just for the view alone, but as a seafood lover, I could have happily eaten here every single meal of my trip.

The menu is extensive, with well over 100 dishes, which can feel slightly overwhelming at first, but trust me, you can’t really go wrong here. I ordered the fried local fish, served with a sweet and spicy Thai sauce that was so good I could have happily licked the plate clean (if no one was watching!).

  • Table set with seafood dishes and a bright orange smoothie in front of a seaside railing decorated with colorful fish illustrations. A sign above reads "KOH MAK SEAFOOD" with the ocean stretching out in the background.

I also tried the Hoy Shell Pad Cha, a generous plate of grilled scallops cooked in a zesty, aromatic sauce with a proper spicy kick. And because I physically cannot order seafood without adding prawns, I can also vouch for the grilled prawns with garlic and herbs.

  • Three plates of seafood dishes including scallops in shells, grilled prawns, and a whole fried fish topped with colorful vegetables arranged on a table. A tall orange smoothie sits in the center with water visible through a railing in the background.

Portions are very generous, so I’d recommend ordering a few dishes to share. Just make sure to save room for dessert; their homemade coconut ice cream is a must!

And just next door, you’ll find the Koh Mak Museum, which is well worth a quick visit after lunch if you want to learn a bit more about the island’s history.

  • Plate of fried whole fish topped with colorful chopped peppers, herbs, and sauce served with fresh greens on the side. A tall glass of bright orange smoothie sits behind the dish on a table.
  • Hand holding a small bowl of coconut dessert topped with peanuts beside a purple orchid flower over calm water. Wooden buildings on stilts blur in the background, creating a relaxed tropical setting.

Enjoy Sunset at The Coral Club

Don’t leave Koh Mak without visiting The Coral Club at least once; it’s hands down the best sunset spot on the island. Formerly known as Banana Sunset, this laid-back bar and restaurant sits on the island’s southern coast and is perfectly positioned for golden hour views.

  • Beachfront restaurant at sunset with wooden tables and benches set on sand beneath trees, string lights and hanging lanterns swaying overhead. A small group of people sits eating by the water as the sky glows orange and pink over distant islands.

But it’s more than just a place to sink beers. Over the years, The Coral Club has evolved into a creative community hub, regularly hosting pottery workshops, yoga classes, live music evenings, and even offering relaxed coworking spaces for both tourists and locals. There’s also a pickleball court where you can watch, or join in, on weekend tournaments, with a free bottle of champagne up for grabs for the winner.

Food-wise, the focus is on wood-fired pizzas, with a fun make-your-own concept starting from 200 THB, so you can customise your toppings exactly how you like.

I ended most of my evenings on Koh Mak at The Coral Club. It’s really the perfect spot to grab an ice-cold beer and watch the sun over the horizon. The vibes are truly immaculate, with friendly staff and chill music to unwind to. Just remember to bring mosquito spray with you if you visit in the evening. It’s open from 5 pm to 9/10 pm daily.

  • Wooden deck seating by the ocean at sunset with low tables and floor cushions arranged under string lights. A palm tree leans overhead while the sky glows pink and orange above calm water and distant islands.
  • Wooden seaside deck with low table and floor cushions overlooking rocky shoreline at sunset. The sun dips toward the horizon casting orange reflections on the water while string lights and leafy branches frame distant island silhouettes.

Coral Planting with Koh Mak Coral Conservation Group

Visitors to Koh Mak can enjoy one of Thailand’s most vibrant marine and coral life, thanks to all the incredible work carried out by the team at Koh Mak Coral Conservation Group (KMCCG) over the years.

If you want to give back to the island and leave it in better shape than you found it, then I highly recommend participating in one of their marine conservation activities, where you’ll get the opportunity to plant coral yourself.

  • Aerial view of a small rocky island covered in greenery surrounded by deep blue ocean. A floating pier extends toward the island with a small boat docked at the end while distant islands fade into the horizon.

I had the pleasure of learning more about the coral conservation work on Koh Mak directly from Pii Ung, the founder of KMCCG. From the moment I met him, it was obvious just how passionate he is about protecting the local environment. Together, we visited the Seagrass House, where he explained how seagrass is propagated in a nursery before being replanted back into the sea to support the island’s ecosystem.

Afterwards, we jumped on a boat to visit one of the conservation sites near a tiny island called Koh Phi, located off the western side of Koh Mak. Here, I was joined by Kun George, another member of the KMCCG team, who guided me through the coral restoration process and showed me the different structures used to help coral grow.

  • Indoor station with a row of white tanks and faucets set up for marine research or conservation work. Educational posters line the wall above with diagrams, photos, and text about seagrass and marine ecosystems.
  • Close up view of green seagrass and underwater plants with a small orange and white fish swimming among them. Tiny bubbles and particles float in the water creating a soft hazy effect.

I’ve snorkelled all over the world, including Egypt, Bora Bora and Australia, but I’ve genuinely never seen such a large amount of colourful coral in one place. It felt amazing being able to contribute, even in a small way, and get a deeper understanding of the impact of coral conservation efforts on protecting marine ecosystems and preserving these reefs for the future.

The Koh Mak Coral Conservation Group regularly host coral planting workshops for tourists. For the latest information and how to book, it’s best to check their Facebook page for updates.

Take a stroll down Cinnamon Boardwalk

If you’re looking for a low-key spot to sip a few beers and watch the sunset, Cinnamon Boardwalk is the place to be.

Once the island’s very first pier, it sits in front of the now-abandoned Cinnamon Scenic Boardwalk Resort, and has since been repurposed into one of Koh Mak’s most unique sunset viewpoints overlooking the sea of Ao Tan Beach.

  • Long wooden pier stretching across shallow calm water with a small thatched pavilion at the end. A tree grows beside the pier while the ocean and distant islands sit under a soft blue sky.

These days, visitors can wander along the wooden boardwalk, which stretches around half a kilometre out over the sea. It’s a little weathered in places and could definitely do with some TLC, but the panoramic views more than make up for it.

There’s a small 50 THB entrance fee, payable at the bar at the start of the pier, where you can also pick up a cold beer or fresh coconut to take with you. It’s also a popular fishing spot, with rods available to rent for around 200 THB if you fancy trying your luck.

  • Aerial view of a long wooden pier stretching through shallow clear water toward a small pavilion at the end. Two trees rise from the water beside the pier while distant islands line the horizon under a hazy blue sky.

Where to Stay in Koh Mak

You really can’t go too wrong when it comes to choosing where to stay on Koh Mak, considering most hotels are either beachfront or just a short 5–10 minute journey from wherever you need to be. That said, I’d highly recommend staying on either the south or west coast of the island, as these areas have some of the best beaches and are perfectly positioned for sunset each evening.

Many hotels on Koh Mak have a strong focus on sustainability, with several being eco-conscious or locally run, and prices are generally very reasonable, especially compared to places like Phuket or Koh Samui.

  • Curved resort pool with clear blue water beside a calm lagoon lined with palm trees and lush greenery. A small thatched hut and stone water feature create a relaxing tropical setting under a clear sky.

On the west coast, take a look at hotels along Ao Suan Yai Beach, such as Seavana Beach Resort, one of the top-rated stays on the island, known for its beachfront rooms and sea views. Nearby, Cococape Resort is another popular option, famous for its long wooden pier and large pool overlooking the sea.

  • Elevated view of a beachfront resort with thatched villas surrounded by greenery and palm trees, overlooking calm turquoise water and distant islands. An infinity pool in the foreground blends into the ocean horizon, highlighting the coastal setting.

On the south side, I loved White Sand Beach Resort, which sits right on Ao Kao Beach, one of the most peaceful stretches of sand on the island. Lazy Day The Resort, located nearby, is another great choice for a relaxed stay.

I’ve also stayed at The Mak Trat on the northern coast of Koh Mak, where I woke up to incredible sunrises and did some very optimistic morning yoga on my private deck before the heat kicked in. The resort is perched slightly on a hillside, which means you get sweeping views across the Gulf of Thailand, especially from the main infinity pool.

  • Garden pathway lined with lush tropical plants leading between modern villas with thatched roofs and small balconies. Sunlight highlights the greenery and curved architecture, creating a peaceful resort atmosphere.
  • Bright bedroom with a thatched dome ceiling and wooden beams, featuring a white bed, woven pendant lights, and a large sliding glass door opening to greenery. A soft beanbag chair and simple wooden furniture add to the airy tropical design.

How Many Days to Spend in Koh Mak

While you can easily cover most of the island within 2–3 days, I’d strongly recommend staying for 4–6 days so you can actually enjoy the slower pace Koh Mak is known for.

Especially if you’re arriving after a visit to Bangkok, your body will be screaming for a bit of rest and quiet. This is very much a “do less, enjoy more” kind of island.

  • Rocky shoreline with dark stones and soft sand meets clear turquoise water where two small motorboats are anchored near the beach. Lush green trees line the coast and a forested island rises in the background under a bright blue sky, creating a calm tropical seaside scene.

Admittedly, I’m the kind of slightly unhinged type-A traveller who has a Google Doc itinerary planned down to the hour, so it was quite refreshing to take a “no plans, just vibes” approach during my time on Koh Mak.

Days here naturally fall into a rhythm of slow mornings, beach hopping, long lunches and early nights, and I promise you won’t feel like you’re missing out by not packing your schedule.

If you’re combining Koh Mak with nearby islands like Koh Kood or Koh Chang, I’d still try to give it at least 3–4 nights, so you definitely have plenty of time to relax and not feel like you’re rushing through it.

  • Wooden lounge chairs sit beneath tall palm trees on a white sandy beach, facing calm turquoise water dotted with dark rocks. A distant island and clear blue sky complete the peaceful tropical scene.

Useful Tips to Know Before Visiting Koh Mak

Bring cash with you before you arrive on Koh Mak. Most restaurants, bars and services are cash only, and there’s only one ATM on the island. You don’t want to end up in an awkward situation if it randomly stops working during your trip.

It’s best to stock up on Thai Baht at Bangkok airport when you can. I recommend bringing around £30–£50 (1300–2000 THB) per day in cash.

Most Koh Mak businesses don’t have a website, so it can be a little tricky to find up-to-date information, which is why I’ve tried my best to compile everything you need to know in this Koh Mak travel guide.

I recommend joining the Facebook group, Koh Mak Connect, if you have any questions during your stay. The members are super helpful, whether you need a taxi driver’s number or a brunch spot recommendation.

  • A beachfront bar with a thatched roof sits along a sandy tropical shore lined with palm trees, decorated with colorful triangular flags strung overhead. A flag on a tall pole waves beside the water while calm sea and a tree-covered coastline stretch into the distance under a clear blue sky.

Signal can be a little patchy in some areas of the island. That said, I was still able to access 5G most of the time with my eSIM. I recommend purchasing an e-SIM from Airalo – use my referral code KELSEY5782 to get £2.50 off your first eSIM purchase. Buy your eSIM before your trip to Thailand so you can activate it as soon as you land in Bangkok.

Also, make sure to download an offline version of Google Maps before you arrive on Koh Mak.

Pack plenty of sunscreen and mosquito spray. While there are small shops on Koh Mak, there isn’t a huge amount of choice, and prices are usually higher than in Bangkok or back home.

  • A shaded garden path lined with stepping stones winds past a small beachside building and lush greenery, with colorful flowers and a large leafy tree overhead. A dog lies resting on the grass while the sandy shoreline and ocean are visible in the background.
  • A curved brick pathway leads through lush tropical greenery and flowering bushes toward thatched roof huts and the ocean beyond. Palm trees and vibrant plants frame the scene, guiding the view to the calm blue water in the distance.

You’ll also want to be mindful of sandflies. They’re tiny (you won’t even see them), but their bites can leave you itchy for days. They’re usually found in shaded areas along the beach, so make sure to apply repellent (eucalyptus spray or coconut oil works really well) after swimming and before sunset.

Don’t expect to find any 7-Elevens here! Koh Mak does not have any convenience stores or fast food restaurants – which is actually refreshing for a change! Ditch your cheese toasties for a week and swap them for authentic homemade dishes, try a Thai Cooking Class and eat the best seafood you’ll ever try at Koh Mak Seafood! 

There’s really not much you need to do to prepare for a visit to Koh Mak. As long as you’ve got cash, mozzie spray and your transfer boat booked in advance, you’ll be absolutely fine and ready to enjoy one of Thailand’s most peaceful islands.

  • A wooden pier stretches over clear turquoise water to two thatched roof huts, backed by a lush green tropical hillside. The calm sea and bright blue sky create a peaceful island setting with rustic structures perched above the water.
