Koh Mak
Koh Mak is a small, flat island in the Trat archipelago that has earned the distinction of being Thailand's first 'Low Carbon Destination.' With no jet skis, no big parties, and limited development, this coconut-plantation-covered island offers a genuinely peaceful escape. The island is only 16 kmΒ² with around 400 permanent residents, mostly descended from the five families who originally settled here. Koh Mak is perfect for travelers who want to unplug, cycle through palm groves, and enjoy uncrowded beaches.
Beaches on Koh Mak
Ao Kao Beach
The most popular beach on Koh Mak, a beautiful crescent of white sand on the southwest coast with crystal-clear shallow water perfect for swimming. Most of the island's resorts line this beach, yet it never feels crowded.
Ao Suan Yai Beach
A long, quiet beach on the northwest coast with stunning sunset views over Koh Chang and Koh Kham. The shallow water stretches far out, making it safe for children. A few beach restaurants serve fresh seafood.
Ao Khao Beach
A secluded beach on the south coast with a more rugged feel, flanked by mangroves and coconut palms. Less developed than the main beaches, offering a true castaway experience. The snorkeling off the rocks is decent.
