Chumphon Pinnacle

Chumphon Pinnacle is one of Koh Tao's most celebrated dive sites, drawing underwater enthusiasts with its dramatic submerged rock formations, dense coral ecosystems, and reliable sightings of large pelagic species — including whale sharks. Located approximately 45 minutes by boat from Koh Tao pier, the pinnacle rises from considerable depth and offers a layered underwater landscape that rewards exploration at multiple levels. Divers can expect large schools of tropical fish, vibrant hard and soft corals, and strong biodiversity throughout the site. Visibility is generally good under favourable conditions, and the varied topography creates distinct zones to explore across a single dive. The sheer scale and life concentrated around the pinnacle make it a standout experience, with reviews from visitors describing it as among the finest dive sites they have encountered anywhere in the world. The site is best suited to Advanced Open Water divers or above, as its deeper sections require greater depth certification and comfort with open-water conditions. Beginners and Open Water divers may still experience shallower sections of the pinnacle, but should discuss options with their dive operator beforehand. The most favourable diving conditions around Koh Tao generally fall between February and October, when seas are calmer and visibility is at its peak. Booking through a reputable local dive shop in Koh Tao is strongly recommended, as operators provide transport, equipment, guides, and up-to-date conditions reports for the site.
