Samran Pinnacle is a dive site in Koh Tao featuring three pinnacles located off Sail Rock. The pinnacles rise to a length of about 30 meters/98 feet and are covered in soft corals and sponges.
Patrolling the area, you will find anything from whale sharks to great barracudas, groupers, shoals of big-eye jacks, and nudibranchs.
The currents are mild to strong and the site can typically be dived only between May and September. Samran Pinnacle is rarely dived since it is not suitable for beginners, but this also means fewer crowds for the experienced who wish to venture here.
