This is not a dive site for inexperienced divers! Years of extensive training in Technical Diving and Cave Diving are mandatory if you want to dive this site. However, if you have the required expertise this is one of the most spectacular cave diving sites worldwide. Naturally, no diving facilities are available on-site -- you will need to bring all of your own equipment.
Chumphon and Sail Rock are the best diving spots I've ever seen. The water is clear, you can see so many different fish and creatures! It can get kinda crowded underwater meaning you pass by other groups of divers but everyone has enough space for themselves.
