Diving the Similan Islands


The Similan Islands in Thailand are thought to have inherited their name from the Malaysian word sembelan, which means nine, as the Similans consist of a grouping of nine granite boulder Islands arranged in a South to North access. All the Islands have Thai names but even your Captain will refer to them by number, starting with Island #1 in the South and finishing ten nautical miles in the North with Island #9. Above the water topography is stunning, lush vegetation topping the Islands gives way to granite boulders or white sandy beaches, surrounded by clear blue water. But it is what lies beneath the water that allows the Similans to lay claim to being one of Thailand and Asia's top scuba diving liveaboard destinations.

    Similans Inquiry

Eastward sites

Eastward sites

Sites on the eastern side of the islands tend to be sand covered fringing reefs predominantly made up of hard coral. The reef plateau’s are around 5-10 metres deep and from here you have gentle slopes heading down to the reef edge at around 20-25m. The Eastern sides of the Similans also tend to have more gentle currents. This makes the Eastern dive sites ideal for both divers of all levels and snorkelers too. On Eastern sites you can expect to see a huge variety of coral reef fish. On sand passes look out for garden eels, blue-spot mask rays and the endemic blue-spot jaw fish. Specials include harlequin and robust ghost pipefish, short pouch pygmy pipehorses and hawksbill turtles.


Westward Sites

Westward sites

Sites on the west side of the islands are a little different. Here giant granite boulders tumble to the sea bed easily reaching depths of 40m. The more exposed side of the Similans can be prone to stronger and more unpredictable currents. The currents have kept the boulders free from a build up of sand, leading to boulder dive sites with a variety of canyons, tunnels, swimthroughs, archways and caverns. It can be more challenging diving but hopefully the increased chance of larger pelagics makes up for that. Also keep an eye out for andaman sweetlips, dogtooth tuna and anglerfish.
