About this site

Angthong Marine Park is a cluster of islands in the Gulf of Thailand off the coast of Surat Thani province, near Koh Samui and Koh Phangan. The park consists of dozens of limestone islands with steep karst cliffs, hidden lagoons, and surrounding fringing reefs, and it is reached by boat trips from Samui or the mainland pier at Don Sak.
