Koh Doc Mai Phuket

Koh Doc Mai lies about 15km east of Phuket and can be reached by day trip dive boat in about an hour. It's a small limestone island that juts from the turquoise blue sea, elegantly providing a great opportunity for some wall diving. Currents and visibility can vary here, but when the visibility is spot on it's a marvellous site that offers aquatic life even to rival the Similan Islands. Leopard Sharks rest on the sand or swim lazily, while smaller creatures like Seahorses and Frogfish, can be found camouflaged amongst the corals and fans sprouting from the sheer limestone walls.

Morays protrude from the many holes and cracks that permeate the wall and Cleaner Shrimps dance in their mouths seemingly unconcerned, picking the scraps of food and parasites from their hosts razor sharp teeth. Depending on the wind direction and sea conditions, one side of Koh Doc Mai should always be relatively calm, making for easy boat entries and exits. Even if the vis here is having an off day, don't get disheartened - there's still plenty of macro life to look for in the nooks and crannies.

For day trip diving to the King Cruiser, Anemone Reef, or Shark Point Phuket, this site - Koh Doc Mai is usually a stop on the itinerary. Lionfish feed on the vast numbers of Glassfish, which inhabit the small coral heads at the bottom of the wall. Eerie caves beg divers to fin closer, wide eyed as they peer into the black holes, waiting for their retinas to adjust to the inky darkness. Safety stops can be done close to the wall where divers can continue to look for critters at 5 metres. As with all dives, make sure the guide uses a surface marker buoy, as there can be a fair amount of boat traffic here.
