Sail Rock (Hin Bai)
หินใบ
An isolated giant rock in the sea between Koh Tao and Koh Phangan, one of the best dive sites in the Gulf of Thailand. It is famous for its "chimney" cave and whale sharks.
Sail Rock lies in the open sea about 20 kilometres southeast of Koh Tao and north of Koh Phangan. A giant rock rises from a seabed about 40 metres deep, shaped like a ship's sail. Underwater, a vertical passage called the "Chimney" runs from 18 metres down to 6 metres. Schools of giant barracuda, jacks, and groupers gather around it, and whale sharks can be seen in the right season. Divers with an Open Water certification can join two-dive trips offered by dive shops, costing about 3,000 to 4,500 baht. Equipment is included, with exact pricing set by each shop. The boat ride takes about 1 to 1.5 hours, and trips are cancelled in rough sea conditions.
