Sail Rock Divers
Sail Rock Divers takes its name from the dive site it's best known for getting people to β Sail Rock, a submerged pinnacle out in the Gulf of Thailand that's widely rated as the best single dive site in this part of Thailand, with a famous vertical chimney swim-through and a real chance of spotting whale sharks in season.
As a 5 Star PADI resort based in Chaloklum, it runs the full training pathway alongside the trips, and the Sail Rock focus in its name is a fair signal of where its expertise is strongest. Being in Chaloklum puts it alongside a cluster of other dive operators in the same village, so there's no shortage of comparison shopping if you want to check a few shops before booking.
For divers whose whole trip is built around that one bucket-list site, this is one of the names that comes up first.
