Diving in Koh Racha

Explore diving in Koh Racha

Two islands make up Koh Racha; Koh Racha Yai (large) and Koh Racha Noi (small). They sit 20km south of Phuket and offer the beautiful white sandy beaches that are synonymous with Thailand.

The waters boast diverse and colorful reefs filled with hard and soft coral. Varieties of anemone fish are plentiful with yellowtail barracuda often schooling above the reef. Keep an eye out in the sand for garden eels and a variety of rays. Deeper outer reefs are formed by collections of large boulders and include some great swim-throughs.

Diving in Koh Racha offers gentle drifts along a sloping rock face, dusted with a variety of coral forests. Large schools of barracuda, octopi and cuttlefish are often be spotted as well the occasional manta ray and whale shark.

When to dive in Koh Racha

The main dive sites are situated on the east side of Koh Racha's large island (Racha Yai) which welcomes most of its divers during May-November. Some of Racha Yai and Racha Noi (the small island) are nicely sheltered, meaning diving in the Racha Islands is possible year-round.

Water temperatures average at 82°F/29°C throughout the seasons and visibility reaches 30m. Head further out from the reefs into the blue to look for leopard sharks, manta rays and whale sharks - present all year to the delight of divers.

Both islands offer an abundance of deep reefs, swim-throughs and wrecks for more experienced scuba divers to enjoy 365 days of the year. Racha Noi welcomes schools of tuna and barracuda. Diving in Koh Racha is pleasant and abundant whatever time you visit.

More Information

Koh Racha is a pair of islands off the southeast coast of Thailand. For diving in Koh Racha, the closest airport is Phuket.

Phuket International Airport is the second busiest airport in Thailand after the Suvarnabhumi Airport in Bangkok. There are two terminals in the airport; T1for international flights, T2 for domestic. The airport is very well-connected to Bangkok (daily connecting flights take an hour). There are direct flights to Phuket from India, Australia, Malaysia, Singapore and Europe.

From Phuket Airport, it’s an hour’s drive to the pier at Chalong - where you will board your ferry to Koh Racha (45m). Koh Racha's larger island (Koh Yao) is where you will stay and the smaller island (Koh Noi) 10km away is uninhabited but great for diving. Speedboats and longtails will take you there.

As one of the furthest islands from Phuket, Koh Racha is delightfully uncrowded and unspoilt. Once there, this small island can be traversed on foot in 50 minutes so getting around is easy.
