Another Full Day Trip to the Gulf of Thailand’s best dive site Hin Bai! More famously known as Sail Rock. It’s a big granite pinnacle that breaks the surface half way between Koh Tao and Koh Phangan and as there are no other rocks around it acts as a congregation point for all the fish in the surrounding area.
Hin Bai dive site
The pinnacle drops down to 30 metres in the sand and is typically dived in a circular route around the rock, spiraling slowly shallower. If currents are strong however, divemasters will guide customers around the sheltered areas, avoiding hard finning in the currents. There are other outer rocks a little deeper that can be seen from the main pinnacle and are home to reef sharks. On a clear day, with light filtering down into the crystal blue water, the granite boulder looks stunning. Enormous schools of trevally are all over the dive site and they energetically harass the smaller fish which bunch together and move as one for protection from these darting raids. Sail Rock is best known for its chimney, a large swim-through that is entered at around 20 metres and can be exited in 2 places, first at around 10 metres or shallower at around 5 metres deep. The chimney’s cavern-like area is a haven for all sorts of fish life like schools of glassfish that appear to block your exit, only to part at the last second to reveal the holes. Truely the best dive site in the Gulf of Thailand!
