Nestled in the Andaman Sea off the west coast of Thailand, approximately 60 kilometers northwest of Phuket, you will find Koh Similan and Surin Islands, Mu national parks, some of the best diving destinations in the country.
Founded in 1982, Mu Koh, meaning “group of islands,” National Park Similan Islands includes an archipelago of 11 islands. Thailand established the five islands of the archipelago of Surin, the ocean border of Myanmar, as a national park in 1981.
While 90% of corals are dead here after water changes the temperature in 1998 and 2010, marine life is back to these islands. The Similans offer exceptionally diverse, ranging from nudibranchs and pipefish to manta rays and whale sharks.

The best way to see these dive sites is by diving cruise “liveaboard” although day trips are available. Here, in no particular order, five of the best diving in the Similan and Surin National Parks.
