Scuba diving in Similan Island
The Similan Islands are a chain of 9 tiny islands in the Andaman Sea, about 100km/62mi northwest of Phuket. The islands are blessed with some of the world’s finest beaches and are surrounded by some of the area's richest waters. The Similan Islands achieved national marine park status in 1982. The national park is closed from May 16 to October 15. In general, the east-coast sites are hard coral reef dives with some soft corals, and a huge variety of marine life. The west-coast sites are slightly more challenging due to their depths and the variable currents around the huge granite boulders, swim-throughs and giant fan corals. The dive sites are suitable for all diver levels. The Similan Islands are very popular for underwater photography--it is a paradise for muck/macro diving. Most popular dive sites The most famous sites are Elephant Head Rock, East of Eden, Richelieu Rock, and Christmas Point. Christmas Point is a site filled with huge granite boulders, arches, and swim-throughs that make a fantastic playground for divers (depth of 10-25m/32-82ft). Whitetip and blacktip reef sharks, Napoleon wrasses, and big schools of barracudas can be easily seen there. Other worth visiting sites, located further up north are Koh Tachai and Koh Bon.
