Yacht Destination

Koh Muk

Koh Muk is a quiet island in Trang Province, best known for its hidden Emerald Cave and relaxed village atmosphere.

A hidden gem with an emerald secret

Koh Muk (also written Koh Mook) feels like a step back in time compared to busier islands. Fishing boats line the shore, local villages dot the coast, and long, sandy beaches are still pleasantly uncrowded.

The island’s star attraction, Emerald Cave (Tham Morakot), is accessed by swimming or kayaking through a narrow sea tunnel into a hidden, circular beach surrounded by cliffs – an unforgettable highlight on any private yacht charter.
