Its name translates to "nine" in Malay, which refers to the number of islands in the chain. Of these nine isles, seven are totally uninhabited, and the remaining two house national park offices.

The Similan Islands were named a national park in 1982 and are characterized by the enormous boulders that line the shores of its beaches.

What brings visitors flocking to the group of islands is the park's diverse sea life. You can snorkel or dive while in the national park and expect to see a plethora of creatures. There are countless fish species roaming the waters of the Similan Islands, including snappers, surgeonfish, giant groupers and butterflyfish.

Octopuses, leopard sharks, whale sharks and manta rays are among the larger beasts you may catch a glimpse of as you move through the seas. Large pods of dolphins reside in the waters nearby to the isles and are most active at dawn or dusk.

Out of the water, you'll find palm civets and flying lemurs, as well as over 20 species of amphibians. The skies above the Similan Islands are also colored with tropical birds, including collared kingfishers and brahminy kites, which you can see on a Similan Islands day tour.
