Nestled in the Marine National Park of the eastern Gulf of Thailand, Koh Mak is a small tropical island in Trat province.
Situated just 20 kilometers south of Koh Chang, this quiet haven is just 16 km2, which makes small enough to explore by foot and easy enough to travel across by bike or moped.
In recent years, this once well-kept secret has attracted an increasing amount of tourists and local holidaymakers, but the the laid-back atmosphere and beauty still remains.
While not as popular as Koh Samui or Phi Phi, Koh Mak is regarded as Thailand’s family island, as it makes for the perfect family getaway.
As with many other Thai islands, Koh Mak boasts clear blue waters and white sand, but what really sets it apart is its community vibe and lack of development.
Compared with the likes of Phuket, Koh Phangan, and Samui, Koh Mak is still relatively unknown, and the growth of this spectacular island has been slow compared to nearby Koh Chang.
Development is limited to a relatively small number of resorts, guesthouses, and small restaurants. Pleasingly, the island isn't overrun with touts and tour packages, and at times you may find you have an entire beach to yourself.
In this post I'll give you my insider tips on the best beaches, the best places to stay, and cover the best things to do on Koh Mak.
6 Best Beaches on Koh Mak
Koh Mak has two main beaches, Ao Kao and Suan Yai, but a little exploration will uncover a handful of others that most visitors miss.
Probably the best thing about each, aside from their pristine waters and white sand, is that they are rarely busy.
All year-round, Koh Mak beaches treat you to a peaceful holiday – yes, even during peak season.
Additionally, since the island is shaped like a star, you can enjoy the sunset in a different location each night.
1. Ao Kao
Of all the beaches on this beautiful island, Ao Kao is the most active and lively – and even that's not very busy at all.
The sand here is lush; as soft as a baby's bottom.
Here you'll find the majority of accommodation, including Ao Kao Resort, Baan Koh Mak, Koh Mak Cottage, Lazy Day Resort, Makathanee Resort, Monkey Island, and Palm Beach.
Aside from the resorts, numerous small restaurants and shops dwell along the main road offering all the usual Thai food and souvenirs.
Ao Kao is simply delightful, but there's more treats in store.
2. Ao Suan Yai
Found on the island’s northwest shore, Ao Suan Yai is the other “main” beach on Koh Mak.
Ao Suan offers a long stretch of white powdery sand and a stunning view of Koh Kham.
Koh Mak Resort and Seavana Resort occupy half of the beach, and the other half is home to a more budget resort, Suchanaree Resort, and an almost century-old wooden house of one of the families that founded Koh Mak.
Ao Suan Yai is also the entry and exit point for boats from other islands and the mainland.
3. Ao Pra
Ao Pra is usually deserted, except for a few locals casting their fishing rods.
The eastern point of Ao Suan Yai extends to Ao Pra and it takes approximately 10 minutes to walk from Ao Suan Yai.
This beach is a shallow bay of clear blue waters, making it perfect for afternoon wading. You can eat there too, at the one small restaurant that adorns the shoreline.
Ao Pra also houses Mira Montra Resort, one of Koh Mak’s newest boutique resorts.
4. Ao Tao Khai
Extending from the northern side of Ao Suan Yai is a small beach called Ao Tao Khai. This beach is a former nesting site for sea turtles.
From Ao Suan Yai, you can reach Aao Tao Khai by walking through the coconut trees or riding your moped or bike along the dirt tracks through coconut fields and rubber plantations.

5. Ao Kra Tueng
This stretch of sand found on the southwest shore of Koh Mak is home to a number of resorts, including Big Easy Resort, Kham Nature Resort, Koh Mak Holiday Beach Resort, and Sky Beach Resort.
A typical tropical beach with all the trimmings, the low tide stretches out the shallows and makes it perfect for paddling. There's also a jetty in the middle of the beach, which can be used as a vantage point for taking pictures.
6. Ao Tan and Ao Talong
On the northeastern shore of the island you'll find two beaches – Ao Tan and Ao Talong.
The sand here is darker and the shore is lined with more mangroves than the other beaches, making it a little less desirable than other parts of the island.
That said, there are a couple of resorts here, namely Green View Resort with simple huts, and Cinnamon Art Resort for more luxury accommodation.
Bear in mind that the island is small, so if you find cheaper accommodation near one of the not-so-amazing beaches you will easily be able to travel to another.

How to Get to Koh Mak
Koh Mak is approximately 300 kilometers away from Bangkok and 40 kilometers from Trat mainland.
To get to the island from the mainland, you will need to take a speedboat from Krom Luang Pier in Laem Ngop.
Several boat operators offer service between the mainland and Koh Mak, but not all of them use the same piers – so always check the pier closest to your accommodation. Just ask the hotel you book with.
A one-way ticket costs 450 Baht for what is usually a 45-minute trip, and travel times are usually 10:30 AM to 4 PM, daily.
Making a reservation is recommended, as seats are limited.

How to Get Around
Getting around Koh Mak is easy.
Rent a bike or moped (ask your accommodation if they offer rentals) and you are already halfway to exploring the whole island.
A motorbike usually costs 250 Baht for an entire day.
Taxis are available on the island for 50 Baht per person, but unfortunately the places they can go are limited due to lack of road access. Please note that public transport is not available.
Other Important Tips
Here's some tips on facilities and other important things to note.
- Don’t rely on the ATM: There is one ATM on the island and it has been known to be out of cash or offline – so bring enough cash with you for your stay. You can exchange foreign cash in some big resorts.
- No 7/11s and supermarkets: There are some small shops that offer basics like sunblock, toothpaste, and snacks, but no 7/11 or big supermarket.
- Be aware of jellyfish: Warmer waters are ideal for jellyfish so just be aware that it is a possibility. Resorts and locals usually warn tourists if one has been spotted, particularly the box jellyfish. Always carry a small bottle of vinegar with you when going to the beach in case of a sting.
- Watch out for sandflies: Another problem on tropical islands such as Koh Mak is sandflies. These nasty insects bite the skin, leaving itchy marks that can last for four days or more. If you are bitten, immediately apply tiger balm on the area.
- Riding around the island: Getting about is easy because the island is mostly flat. However it always pays to carry a map and compass, or both on your phone.
10 Best Things to Do On Koh Mak
Koh Mak is a small island but there are a number of things to do. Here's 10!
1. Paddle in glass-bottom kayaks
What’s more fun than kayaking? Kayaking with glass-bottom kayaks!
Enjoy the clear waters of Koh Mak as you paddle along with the sunrise or sunset as your backdrop. Ask your resort or accommodation if they have kayaks for rent.
2. Visit the white-sand beaches
Obvious, maybe, but many visitors stick to Ao Kao and miss the glory of the others. It's best to rent a moped and do a beach or two a day, depending on how long you're there for.
3. Learn to dive
Koh Mak offers diving lessons for relatively extra affordable rates. You can enrol at any of its three diving schools, BB Divers, Koh Mak Divers, and Paradise Divers and become a PADI-certified diver. These schools also offer snorkeling services.
4. Go snorkeling
If diving is a bit too involved, snorkeling is a less complicated option. You can either join a snorkeling tour or bring your own snorkel set with you.
Kayaking and snorkeling is a fun combo; just ask your accommodation or the locals where the best snorkeling spots are.
5. Enjoy sunset at Banana Sunset Bar
True to its name, Banana Sunset Bar has one of the best views of the sun setting over the sea.
Grab a drink and some snacks and indulge in the peaceful atmosphere of the bar as you marvel at nature’s wonders.
6. Hit some walking trails
Nature lovers will love Koh Mak's forests and coastlines.
By following bicycle paths and walking trails, you can visit several places, such as the oldest house and the original fishing communities Laem Son, and Laem Tookata.
Koh Mak doesn't do traffic, so make the most of it!
7. Take a cooking class
Smile Koh Mak Cooking School offers cooking classes for small groups (maximum of 4 persons). Thai food is awesome, so why not learn how to cook your favorites so you can make them when you go back home.
8. Visit the Buddhist temple
Overlooking Ao Nid Bay and occupied bt several monks, the small Buddhist temple on the island is the central point for the community.
You might notice that the golden statue of Buddha has a more feminine touch. This is because the wife of the island’s founder supported the temple’s construction.
9. Visit The Kingdom of Somchai’s Affection
The Kingdom of Somchai’s Affection is not your typical garden of statues. The style of art on display here is quite unique to the artist, Khun Somchai. Take a stroll around the garden and see (or gasp!) at the erotic statues.
This exhibition is suggested for those 18 years +.
10. Muay Thai training
The Hongthong Muay Thai Gym, popular in Bangkok and Chiang Mai, also has a branch on Koh Mak. It's located beside Coco Café at the top of Ao Kao Resort road.
Depending on the package you want, prices range from as low as 400 Baht to 24,000 Baht.
