The beautiful Similian Islands are a group of nine islands, and lay claim to being one of the top dive destinations in the world.

To the north, the Surin Marine National Park consists of five granite islands covered in lush forest with idyllic beaches and beautifully clear water.

Immerse yourself in thriving reefs, lush corals, impressive sea fans and an incredible variety of marine life including large pelagics such as manta rays and whale sharks. Gigantic boulders, above and below the water line create awesome underwater scenery and exciting swim throughs.

Although some sites can be reached from resorts in Kao Lak, it is best to visit this region by liveaboard. A visit to Richelieu Rock is a must, most famous for sightings of whale sharks and manta rays. This submerged rock is surrounded by a series of underwater pinnacles covered in corals and sea fans and is incredibly rich in marine life, making this a spectacular wall dive.
