Ko Mak

Ko Mak is a small low-lying island in Ko Kut District, Trat Province, in eastern Thailand near the Cambodian border. Part of the Mu Ko Chang National Park archipelago, it lies between Ko Chang and Ko Kut. Known for its flat terrain, coconut and rubber plantations, clear water beaches and quiet atmosphere, it has limited development, family-owned land, and a focus on low-impact tourism with cycling and snorkeling as main draws.

Visitors can expect a quiet, flat island with long sandy beaches, clear shallow water, coconut groves and rubber plantations inland. The island is small enough to explore by bicycle or motorbike on paved roads. Beaches such as Ao Suan Yai and Ao Kao offer swimming and sunset views. Small piers, resorts, restaurants and dive shops are scattered around the coast, with snorkeling trips to nearby islets and a relaxed, low-density resort environment.

Ko Mak was historically covered with coconut and rubber plantations. In the early 20th century land was granted to the family of Luang Prompakdee, and much of the island remains privately owned by descendants. Development has been intentionally kept low-density compared to neighboring islands.

The island is known for its small local community, fishing heritage, and community-based low-impact tourism approach. Local lifestyle centers on fishing, agriculture and small-scale tourism services.
