This collection of islands is even more enchanting below the surface than it is above. White beaches and crystalline waters give way to countless species of marine life (yellow boxfish, sea turtles, blue surgeonfish, manta rays), which are frequently seen by snorkelers and divers. Birds abound, too, with olive-backed sunbirds, yellow-rumped flycatchers and white-breasted water hen inhabiting the environs.
The Similan Islands is a cluster of eleven islands that are actually part of the Mu Ko Similan National Park, located off the coast of Phang Nga bay. The waters around these islands are home to a plethora of diverse marine ecosystem which provides some excellent diving and snorkeling spots.
