Surin Islands Liveaboards – Richelieu Rock and Northern Andaman
The Surin Islands are the northern end of a Thai liveaboard route, close to the border with Myanmar in Thailand. The park includes shallow fringing reefs around the islands and Richelieu Rock, the best-known dive in the Andaman Sea. Longer Similan & Surin trips give you more time up here.
