Koh Mak is one of the largest islands in Trat Province, covering approximately 9,000 rai between Koh Chang and Koh Kut. The island is well known for its distinctive star-like shape and flat terrain, largely covered by coconut and rubber plantations. Unlike many busy tourist destinations, Koh Mak follows a “Low Carbon” concept, preserving its quiet atmosphere, clean environment, and strong local community identity.

The island’s history dates back to 1904 during the French Indochina period, when Khmer Thais and Chinese families migrated from Koh Kong under the leadership of Luang Phromphakdi. Today, their descendants continue traditional agricultural practices, especially coconut and rubber farming. A 27-kilometer ring road circles the island, making it easy to explore by motorbike or bicycle—one of the few Thai islands suitable for cycling due to its flat terrain.
