About Koh Rin

Koh Rin is a military-controlled island that benefits from restricted access — the reef is healthier than anywhere else in the Pattaya area. The island's reef drops to 22m with excellent hard coral coverage and regular hawksbill turtle encounters. Barracuda and large groupers are common on the deeper sections.
