KohMook is a large island comparing with nearby islands but little smaller than KohLibong. It is well known as the owner of Morakot Cave. KohMuk is virtually more interesting for its beautiful beaches of fertile natural surroundings. It is the island of ancient communities mostly Muslim. Villagers normally use long-tailed boats to travel between the island and Kuan Tung Ku Pier taking only about 15 minutes.
Most tourists prefer to use the package tour service which includes the tour program of other nearby islands.
