Koh Doc Mai is not far from Chalong Bay and is a little island with limestone cliffs rising out of the water and underwater cliffs dropping to 25-30m. It is a wall dive often with a current that can make it a great drift dive. There is much to see tucked in the cracks along the wall. From bamboo sharks to ornate ghost pipefish and seahorses. Koh Doc Mai also has one of the best selection of nudibranches.
When diving the wall do keep an eye out
Often used as a dive site on the way to/from the King Cruiser Wreck, Shark Point or Phi Phi, it is considered the best wall dive in the area. The larger east face and smaller north and south
The base of the island meets the sloping bottom at depths of between 18-22m, where the bottom continues out to 30m and 40m in some places. Predominantly a sandy-rubble base on the east, north and south and a soft sandy base with large soft coral covered boulders on the west. This dive site can be prone to strong currents (great for drift diving) and very varied visibility – on a good day it can be stunning, particularly in the current – on a bad day, visibility can be as low as 3-5m.
Koh Doc Mai is well suited for experienced divers who want to see something special or for those on more advanced courses or drift diving courses.
