Koh Haa (Haa Islands)

A tiny group of five islets and a central lagoon between Koh Lanta and Koh Rok, famous for clear water, caves and spectacular snorkeling and diving.

A natural lagoon in the open sea

Koh Haa (literally “Five Islands”) is a compact archipelago that feels like a private playground in the middle of the Andaman Sea. The central lagoon is formed by a ring of steep limestone islets, creating calm, pool-like water that is perfect for swimming and paddleboarding.

Beneath the surface, you’ll find caves, caverns and sloping reefs, making Koh Haa one of the most interesting snorkeling and diving spots on Thailand’s west coast.
