Koh Mak is a small island of Trat Province, Thailand. The island is named after the Areca nut.
The first settler on the island was Chao Sua Seng, a Chinese Affairs Officer during the reign of King Rama V, who established a coconut plantation. He then sold the plantation to Luang Prompakdii, also a Chinese Affairs Officer whose descendants still own the land to this day. Luang Prompakdii and his children are known to have established more coconut and rubber plantations, effectively covering most of the arable land in these two sought after exports at the time.
The first attempt at attracting a tourism market was in 1974, when bungalows were built at Ban Ao Nid on the east of the island. Infrastructure, specifically transport and telecommunications were in their early stages and as a result, the tourism industry on Koh Mak took some time to become established. By 1987 certain beaches and land were cleared and the first resorts were built.
The island of Koh Mak is situated in the East of the Gulf of Thailand, 35 kilometers from the mainland, and is the third largest island in Trat Province, after Koh Chang and Koh Kut. With an area of 16 square kilometers Koh Mak has 27 km of coastline, many long sandy beaches, and a few hills. The island is home to approximately 800 locals and renowned for its beautiful beaches, having been included in the U.K’s Sunday Times 10 most beautiful beaches list in 2006. Koh Mak has a temple, a primary school, 3 fishing villages, a market and a health center.
