Koh Doc Mai it's one of the most famous dive location in south Thailand. It's a wall dive site, a rock wall slope down until 32 mt depth , completly covered from spectacular marine life . Loved from underwater photographer for his macro life. It's suitable for advanced / expert divers , cave diver The Island Koh Doc Mai is huge submerged limestone rock. On the West side you can find a gentle slopping reef and on the East side is a sheer wall. It?s sometimes is overlooked by divers because of the occasionally bad visibility and strong currents. However this is not correct, this is one of the best dive sites in Thailand for the avid macro enthusiast. It?s fantastic. Most of the Phuket Diving tends to be focused on the East side of the island. There are two large caverns here one with an entrance of 5 meters. Here you will be able to find some very unusual marine life consisting off, seahorses, frog fish, white eyed moray eels, sea snakes, and pipefish. The island just has it all. Look out for the many species of nudibranch?s around the 5 meter mark, and excellent place to make your safety stop!
