About this activity

Explore Mu Ko Ang Thong National Marine Park, a protected 42-island archipelago in the Gulf of Thailand, on a full-day snorkeling and sightseeing adventure by speedboat. This Ramsar-designated site combines underwater exploration with emerald lagoons, limestone cliffs, and optional jungle hikes—all in one immersive day trip from Koh Samui.

Established as a marine national park in 1980, Mu Ko Ang Thong National Park is an archipelago of 42 islands covering 102 km² at the shore of the Surat Thai Province east of Ko Samui in the Gulf of Thailand. The park is registered as a Ramsar site by Ramsar Convention, an international treaty for recognition of important wetlands. Many sources refer to the islands as "Angthong" which is wrong, "Ang Thong" is the correct spelling and means "golden bassin".
