Thailand's most unspoiled island.
No high-rises. No 7-Eleven. No crowds. Just sixteen square kilometres of coconut groves, clear shallow sea, and a pace of life that invites you to slow down.
A small, privately owned island in the Koh Chang archipelago, Trat province in the Gulf of Siam, where development and mass tourism are deliberately limited — coconut plantations, two white-sand bays, and a world away from the rest of Thailand.
Nature, Sports, Serenity
Sixteen square kilometres of rubber plantations, jungle interior and two sweeping white-sand bays — almost entirely undeveloped.
Muay Thai - rumble in the jungle, Tennis with ocean-breath, yoga by the sea, and many other sports facilities on Koh Mak, such as pickleball, scuba diving, basketball, and running.
No clubs, no walking streets, no 7/11, no jet-skis. The loudest things you'll hear are waves, geckos, and the occasional gentle sound of a falling coconut.
