About this site

Koh Doc Mai sits in Phangnga province, Thailand, near the popular dive grounds around Phi Phi and the Andaman Sea approaches to Krabi, known locally for a steep wall dropping along one side of the small island. The site reaches a maximum depth of around 30 metres over a reef bottom, with good visibility and light current, and is generally rated a beginner dive. Ghost pipefish, nudibranchs, and seahorses are common finds along the wall. Divers have also reported barracuda, jacks and amberjack, leopard and zebra sharks, lionfish, moray eels, ornate ghost pipefish, parrotfish, pufferfish, scorpionfish, sea turtles, snapper, squid, stingrays, and tuna. Some have noted caverns and cave-like sections that call for proper training to explore, along with stronger currents at times and the presence of white banded sea snakes.
