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

There is the Similan Islands National Park, which is a set of 11 designated islands; formally known as the Mu Ko Similan National Park. 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.
