Koh Mook is a pristine island crisscrossed by narrow dirt roads, leading to breathtaking water caves and secluded beaches that offer some of the most stunning sunsets in Thailand.

Despite its beauty, Koh Mook retains its authentic local charm and is relatively untouched by mass tourism.

Meals can be enjoyed for under 100 THB (around USD 3), and the island’s village lifestyle remains unspoiled.

Koh Mook is situated just 15 minutes off the Thai mainland in Trang Province. It is one of the many islands in the Andaman Sea, boasting crystal-clear waters perfect for snorkeling or simply relaxing with a fruit shake by the beach.

Things to Do on Koh Mook
