Boat-access limestone wall and slope with macro life.
Boat access, current management, and wall-route choices make local guide support the normal way to dive the site.
Koh Dok Mai is a boat-access limestone wall site east of Phuket where the east side drops into steep vertical faces and the west side eases into a gentler slope. The site is defined by soft corals, sea fans, crevices, and caves that reward careful buoyancy and a slow look for macro life rather than fast reef cruising.

Site Conditions
Safety Notes
Plan for drift-style wall diving, keep buoyancy tight around the caves and overhangs, and dive the current window the guide sets.
Access Restrictions
Boat access is the normal setup, and the caves and wall profile call for guided planning rather than casual exploration.
Legal Notes
Follow guide briefing, respect cave and overhang limits, and stay inside the current plan for the day.
Community notes to help plan your visit.
Scuba Diving
Scuba divers can explore the steep east wall and the gentler west slope.
Freediving
Not a freedive-first site; the wall, caves, and current make it a scuba-led dive.
Snorkeling
Not a casual snorkel site; the best features sit below the surface and suit scuba planning.
