Why go

Racha Yai is a small island south of Phuket with white beaches and very clear water, popular for snorkelling and diving.

Racha Noi, nearby, is a well-known dive site.

Siam Bay and Patok Bay are the main bays.

Racha Yai's Siam Bay has calm water and soft sand. Patok Bay is quieter.

Divers love Racha Noi for manta rays in some seasons.

Racha Yai is shaped like a horseshoe, with Siam Bay (often called Ao Bungalow) at its heart. The beach slopes gently into water so clear you can see fish from the sand. A short walk across the island leads to quieter coves and rocky snorkel spots.

Because it's a little further than Coral Island, it attracts fewer large groups, and in the late afternoon, after the tour boats leave, it's genuinely peaceful.

The story

The Racha islands are a favourite of Phuket dive schools.

The island has a small resort and little else.

Racha islands have been a quiet escape since early tourism.

Dive schools teach many first-time divers here.

Diving instructors around Phuket often call Racha Yai their classroom: calm, clear bays where first-time divers learn to breathe underwater. Racha Noi, smaller and wilder, is for more experienced divers, with deeper walls and strong currents, and it's known as a place where manta rays and whale sharks are occasionally seen in season.

The islands were sparsely inhabited for most of their history, used by fishermen as a stopover and later by a handful of coconut farmers before tourism arrived.

Getting there

Speedboats leave from Chalong pier.
