Big Blue Diving
A village-like compound at the north end of Sairee Beach running one of the island's larger course operations, plus daily fun-dive boats to the pinnacles and reefs. Freediving and tech offshoots exist alongside the recreational school, and the social scene is part of the draw.
Harga: Budget-to-mid band typical of Koh Tao, with room-and-course packages. Verify schedules and current pricing with the shop.
