Similan Islands Phuket Tour Guide 2026: Tickets, Activities, Best Time & Travel Tips

The Similan Islands National Park consists of 11 designated islands, formally known as Mu Ko Similan National Park (including Ko Bon and Ko Tachai, added in 1998). The park, which was established in 1982, is well-maintained in order to conserve the delicate ecosystems of marine life and tropical life forms.

The naming system of the Similan Islands is named after the Malay sembilan, which means nine, and it was originally the first nine islands. Islands 1-11 are now under protection, with the key areas being Islands 4 and 8, where visitors can explore.

The underwater visibility, the healthy coral systems, sighting of the whale sharks, manta rays and the colourful reef fish have helped Similan Islands to be ranked among the top 10 snorkelling and diving spots in the world.
