Similan Islands National Park

Similan Islands National Park is made up of 9 different islands located in the Andaman sea, about 90 km North West from Phuket and 60 km West from Khao Lak. The area is reachable on 1-day diving trips from Khao Lak and by 4-5 day diving liveboards. In addition, a wide range of non-diving daytrips are conducted around the these magnificent islands that involve sightseeing, jungle walks and snorkeling.

The Similan Islands are classified as one of the best diving areas in the world and it was one of the favourites of the pioneer Jaques Costeau and his team. The gigantic gorgorian fans, colourful soft corals and huge rocky boulders with swim-throughs makes the scenery very attractive. There is an endless variety of fish species and Manta Rays and Whale Sharks are common sightings in the region.

Similan Islands National Park is closed during off season from May until October.
