The Similan Islands, Koh Bon, Koh Tachai, Richelieu Rock and Surin islands are located to the north-west of Phuket, and to the west of Khao Lak.

The boats leave from either Phuket or Khao Lak, depending on the boat you choose. Of course we will provide a transfer from your hotel to the boat and back.

The main season here runs from October until May, when visibility can be (and normally will be) as good as 30+ meters. But also outside this season you can enjoy diving at the Similans on a liveaboard. Click here if you want more information on this.

Similan Islands are a stunning group of nine islands, north-west of Phuket. The diving here is astonishing; one of the top spots in the world and Asia and together with the other liveaboard destinations the best in Thailand.

Thriving reefs, lush corals, impressive sea fans and an incredible variety of marine life including large pelagics such as manta rays and whale sharks.

The Similans are characterised by gigantic boulders above
and below the water line, creating awesome underwater scenery and exciting swimthroughs for divers to explore. The water is crystal clear and the visibility is fantastic.

The Similans also have exquisite sandy beaches and shallow coral reefs in the bays, which are perfect for snorkeling. Spread among the nine islands are about 20 different dive sites.

Fantasea Reef is one of the favourite divesites, especially for photographers. Thousands of schooling fusiliers and banner fish together with the always present sharks make this an awesome dive.

Christmas Point is another Top Site. This is a good spot for manta rays, nurse sharks and barracudas. It has an impressive variety of hard and soft corals and a wonderful maze of swimthroughs. Shark Fin Reef has beautiful coral and sponge gardens. It is an excellent site to see reef sharks and huge Napoleon wrasse.

Elephant Rock looks from the surface like an elephant head. Below the surface there are many impressive tunnels and swimthroughs. You can find small white tip reef sharks in a rock crevasse at the start of the dive and lots of colourful fish.

Boulder City is another favourite site of the Similans. Due to its exposed location it is possible to see almost anything here including whale sharks and mantas. It is always an exceptional dive. Leopard sharks, spanish dancers and great barracudas have been seen here against a backdrop of huge granite boulders.
