Koh Doc Mai

Koh Doc Mai, meaning Flower Island, is a small, limestone island, covered in vegetation and situated one hour southeast of Phuket. This dive site has plenty to make it really worth a visit – its vertical cliffs offer a stunning wall dive, and it is ideal for drifts since the waters around the island can experience moderate to strong currents.

Koh Doc Mai Information

  • Time to dive site: 1.0 hour by dive boat
  • Diver level: Intermediate to advanced
  • Currents: Mild to strong
  • Depth: 5 – 28m


Depth ranges from 5m – 28m, and there is an abundance of cracks, rocky overhangs and ledges to investigate, whatever your depth. On the east side of the island you’ll find two caves, one large cave at 18m, and one smaller at 22m, so take a torch! Whilst the larger of the two caves is easy to swim in and around, the smaller one is certainly cosier, therefore only recommended for sufficiently experienced divers.

A wide variety of special, smaller sea life can be sighted at Koh Doc Mai, so plan a gentle, multilevel dive and take your time exploring the wall to see ghost pipefish, many species of nudibranchs, lots of different types of eels, spiny lobster, dancing shrimp, sea fans, and even seahorses. Look out for some of the bigger fish at this dive site too – barracuda are frequently spotted, and it has even been known to host the occasional Whale Shark.
