The Similan Islands are ranked as one of the top dive destinations in the world. Made up of 9 granite islands, located 100 km Northwest of Phuket and 65km offshore from Phang Nga Province in the Andaman Sea, the Similan Islands were declared a National Park in 1982 and offer scuba divers exceptional diving adventures. Similan Island liveaboards will visit dive sites that feature varied landscapes and vibrant marine life.

The East Coast boasts exceptional visibility and weak to moderate currents while the West Coast waters are deeper with stronger currents. With such varied dive sites, the best way to enjoy the Similan Islands is on a premier dive liveaboard.

Similan Islands Underwater

The landscape of the Similan Islands is a feast for the eyes both above and underwater. From the tropical white sandy beaches and clear blue waters to the granite boulders on land and underwater, it is a paradise difficult to surpass and understandably one of the most popular dive locations in the world. It is becoming ever more popular to take a dive safari on a liveaboard due to easy access to these remote islands. An abundant marine life roams the subterranean landscape of these islands. It is common to see leopard sharks, guitar rays, whitetip sharks, blue-spotted stingrays, clown triggerfish, rabbitfish, scorpionfish, snappers, emperor fish, giant trevally and angelfish. Turtles and giant bump head parrotfish make their appearances and the sharp-eyed diver may find tiny ghost pipefish, mantis shrimps, porcelain crabs or cleaner shrimp. To dive amongst the boulder formations and see their impressive size underwater is truly wondrous.

With an average depth of 15-20 meters, the reef is decorated with hard corals, keep an eye out for shy garden eels on the sandy bottom.

Christmas Point, true to its name, is one of the most colourful, scenic dives in the islands on the far west side of Similan Island 9. This outcropping is home to several giant archways which provide superb topography and forms some of the best swim-throughs in the Similans.

Other dive sites include: Three Trees, Beacon Point, Breakfast Bend, Chinese Wall, Coral Reef, Deep Six, Hideaway, Deep six, North Point and Stonehenge.

Top Tips For Divers

Thailand liveaboard trips to the Similan Islands run from November through to May. The Islands are closed for the rest of the year. The end of February often sees an increase in currents attracting the larger marine creatures like whale sharks and manta rays. Visibility ranges from 25-40m during this period and water temperatures range between 26-29c. You may not need more than a 3mm neoprene shorty or full body wetsuit bearing in mind after a 3 or more dives a day, you may get cold. If you are bringing your own equipment, consider bringing a DIN adapter (if you have DIN regulators) as Thailand uses the standard yoke system.
