Gulf Fins Koh Tao

About this school

Gulf Fins is a laidback, eco-conscious dive centre on Koh Tao's Sairee Beach side, beloved by long-term island residents and backpacker divers for its small groups and highly personalised instruction. They specialise in tech diving courses and nitrox fills alongside standard recreational training, and their guides know every macro critter hotspot around the island — from ghost pipefish to blue-ringed octopus. Night dives off Ao Leuk Bay are a house speciality, revealing the reef's dramatic transformation after dark.
