Sail Rock is without doubt the best dive site in the region. Chumporn Pinnacles is similar but as Sail Rock extends above the surface, it opens up a whole range of options and things to see towards the end of a dive within the 12m - surface zone. Although there is a large variety, it is the sheer volume of marine life that inhabits the main and satellite pinnacles that almost guarantee astounding dives here. Highlights are typically the enormous schools of Bigeye Trevally, Pickhandle and Chevron Barracuda, impressive Brown-Marbled and Malabar Groupers and of course, the occasional nomadic Whale Shark.
