Crystal Waves Thailand - a PADI 5 Star IDC Center
Koh Doc Mai

Koh Doc Mai

Koh Doc Mai is a limestone island that rises vertically from the seabed.

Some say it looks like a muffin with the jungle clad top flowing out over the sheer cliffs.


  • Limestone Islands
  • Garden of Hard & Soft Corals
  • Tropicals, Moray Eels, Octopus, Sharks
  • Moderate to Strong Currents
  • 10 to 15 Meters Visibility
  • All Levels of Diver


Although the visibility at this site is generally not as good as others, this dive is noted for the variety of reef fish and as such you might be lucky enough to encounter Leopard Sharks, Moray Eels, Octopus and Turtles. The east-site of the island consists of a vibrant garden of yellow tube corals as well as two small caverns.

Koh Doc Mai is located on the way to Shark Point and offers an interesting alternative to the pinnacle dives as it is one of the best wall dives in the area.
