Crab Island is just a few hundred meters from the shore of Koh Phuket. The dive site is very shallow with a maximum depth of 10 m. The spot is perfect for dive training, underwater macro photography, and night dives in Phuket. It is also a great spot for Snorkellers. You can spot Turtles, blue spotted Stingrays and all the usual reef fishes of the Andaman Sea. If you are on the look-out for macro critters, here you can find various species of nudibranch, frogfish and Scoprionfish.
You can dive Crab Island all year long. Access: Boat. See the map of Crab Island on the right for the exact location.
