About this site
Koh Dok Mai is a wall dive about one hour by boat from Chalong Pier, Phuket, and is described as the only wall diving site around Phuket. The wall is covered in soft corals, which shelter a wide range of marine life.
This is a good site for macro. Divers find nudibranchs, flatworms, and various species of shrimp and crabs. Larger animals include barracuda, snapper and moray eels.
The site is exposed to strong current, and visibility is poor. The maximum depth is about 30 m and the wall dive is rated advanced. Snorkelers stay on the boat for this site because it is exposed to strong current. Divers should expect a wall dive in water that can run murky, so good buoyancy and a plan for the current are worth having.
