Whether you've never breathed underwater or you're logging dive number 500, Koh Tao's schools run trips every day. Beginners start with a Try Dive: a briefing, a shallow skills session, then a real guided reef dive with an instructor beside you. Certified divers take the morning boat to the island's best sites, granite pinnacles wrapped in barracuda, turtle bays, and in season the slow shadow of a whale shark. You book directly with the island's dive centres.
