Similan Island

The Similan Islands National Marine Park (Mu Ko Similan) is probably the most famous and offers some of the best diving in Thailand. It is officially part of Phang Nga province and is situated on the south-west coast of Thailand, out in the Andaman Sea. There are nine main islands in a north-south line which make up what most people know as the Similan Islands. A little way north, there are also a couple of other remote and uninhabited islands officially in the National Marine Park, but listed here separately as Koh Bon & Koh Tachai. Diving at the Similan Islands is something that anyone who enjoys diving should try at least once in their lives. The turquoise waters are crystal clear and often allow divers to descend to 50 metres or more. Most of the islands' diving sites are made of granite boulders and offer lots of exciting diving opportunities and interesting marine life. Whale Sharks and Manta Rays are seen regularly, as well as predatory sharks and other rays. The sea conditions, such as visibility and currents are ideal for wonderful, but occasionally challenging scuba diving.
