Ko Kut

Ko Kut is a large island in Ko Kut District, Trat Province, in eastern Thailand near the Cambodian border. Known for its undeveloped coastline, clear waters, white-sand beaches and interior forest with waterfalls such as Khlong Chao. The island hosts small fishing villages, coconut plantations and low-density resorts. It is noted for tranquil beaches, snorkeling and kayaking opportunities and remains less developed than nearby Ko Chang.

Visitors can expect a quiet, low-density island with white-sand beaches on the west coast such as Ao Tapao and Ao Phrao, clear turquoise water, and forested interior with waterfalls including Khlong Chao Waterfall. The landscape includes coconut groves, small fishing villages like Ao Salad and Ao Yai, and scattered resorts. Activities center on swimming, snorkeling, kayaking, cycling and boat trips to nearby islets. Infrastructure is limited with few roads, small shops and piers connecting to the mainland by ferry and speedboat.

Ko Kut is part of Trat Province which was under French occupation from 1904 to 1907 and returned to Thailand under the Franco-Siamese Treaty of 1907. King Rama VI visited Khlong Chao Waterfall in 1911. The island has historically been inhabited by fishing communities and coconut plantation workers.

The island maintains small coastal fishing communities at Ao Salad and Ao Yai with traditional livelihoods, local seafood culture and Buddhist temples serving residents and visitors.
