Gulf of Thailand: Samui and Koh Tao

The only route on Thailand’s east coast — in the Gulf of Thailand, near Samui and Koh Tao Islands. The region offers diverse dive sites with hard and soft coral reefs, granite pinnacles, and rich marine fauna. Whale sharks regularly appear in Koh Tao waters.

Chumphon Pinnacle — the route’s main site, a granite peak at 10–30 meters depth with soft corals and schools of barracuda. Southwest Pinnacle and Hin Wong — two more underwater granite peaks with gorgonians. Shark Island and White Rock offer coral gardens with tropical fish. Koh Nang Yuan — a scenic island with recreational shallow diving. Laem Thian — caves and rock passages. The route suits divers of all levels and operates in the alternative season compared to the Andaman Sea.
