About this place

Located 8km north of Koh Tao, this limestone pinnacle rises from 40m depth to just below the surface, creating a unique ecosystem that attracts large pelagic species. The site features a distinctive swim-through chimney and is considered one of the best places in the world to encounter whale sharks, especially between March and September. Book early morning dives for the best visibility and whale shark encounters.
