Escape the Crowds. Thailand's Sporty Island Paradise
 Koh Mak 

Unspoiled. No 7-Eleven by choice. No crowds. Just sixteen square kilometres of coconut groves, clear shallow sea, and a pace of life that invites you to slow down. And because of some locals' passion for health & sports, you find a high number of sports facilities in this secluded destination, such as Muay Thai, tennis, yoga, basketball & more.

An introduction

Koh Mak is a small Thai island in the Gulf of Thailand — quieter than Koh Chang, wilder and with more community and sports than Koh Kood, and still largely off the map. Peaceful and chilled.

The beaches on Koh Mak are long, uncrowded, and clean. No jet skis. No beach touts. Two main strips — Ao Kao and Ao Suan Yai — plus a handful of hidden coves most visitors never find.

The best hotels and resorts on Koh Mak stay small by design. The families who own this island have kept developers out for decades. That's why it still feels like Thailand used to. And people fall in love with the island, or leave the next day when they do not find the kind of bars they were looking for. 

Getting to Koh Mak is straightforward — speedboat from Laem Ngop pier in Trat, about 50 minutes. Fly Bangkok to Trat, or take a bus. The ferry and boat schedules run year-round, with more frequency in high season. Once you land, see how to get around Koh Mak.

Things to do on Koh Mak go deeper than the average island. There's Muay Thai training, tennis, pickleball, yoga, kayaking, and one of the best diving and snorkelling zones in the eastern Gulf. The nearby marine park around Koh Rang is world-class.

Comparing Koh Mak vs Koh Chang? Koh Chang has more — more nightlife, more roads, many more 7/11, more tourists, more gogo-bars, more everything. Koh Mak has less, on purpose. That's the point.

For food and restaurants on Koh Mak, kitchens are small, local, and good. Seafood straight off the boat. No tourist menus. No scam, no crime. Planning a longer trip? Check practical info and Thailand visa options

One island. No crowds. Evolving to Thailand's recognised sports hub.
