The ULTIMATE Similan Liveaboard Adventure…

The above water scenery will provide stunningly beautiful white sandy beaches with small forested areas. Dive some of the following sites; Boulder City, Sharkfin Reef, Anita’s Reef, and Three Trees.

Under the surface, you may see Leopard (zebra) shark, blue spotted stingrays, clown triggerfish, rabbit fish, scorpion fish, snappers, emperor fish, giant trevally and angelfish. The coral gardens, bommies, and boulder formations are wonderful to dive.

Elephant Head Rock, visible from the surface, is the biggest pinnacle in the Similans and has some fantastic swim-throughs. Whitetip reef sharks, batfish, trevally and barracuda can often be seen on the perimeter of the boulders. If you look closely in the cracks and in the rubble you can see smashing mantis shrimp, porcelain crab, moray eels and cleaner shrimp.

There are also sites dominated by huge granite boulders such as Deep Six, Christmas Point, and North Point where you can see white tip reef sharks, schooling giant trevally, and schools of neon fusiliers.

This is generally the most likely place to see manta rays on our Similans itinerary. You are also likely to see Napoleon wrasse, sweetlips, octopus, bluefin trevally, giant moray eels, great barracudas, fire dart goby, spiny lobster, and nudibranchs of many types. The dive sites vary from wall diving to gently sloping reefs and from submerged boulders to coral gardens.

Diving on the West Ridge can be an adrenaline-filled drift, with amazing views, while the North Reef is a gentler experience over a hard coral garden.

This island is famous for its pinnacle dive site, known by many as Twin Peaks, as well as more relaxed reef diving on the North Reef and South Reef. Normally, turtles, barracuda, pipefish, and nudibranchs can be found here. There is also a chance to see bigger species in this area like manta rays and whale sharks, especially from late January until April.

The topside scenery of Koh Surin, with evergreen forests, mangroves, and small beaches, surpasses even that of the picturesque Similan Islands.Underwater the reefs of Surin offer some of the greatest hard coral diversity in Thailand.

Across sites like Torinla Pinnacle, Hin Kong, and Turtle Ledges you are likely to see Napoleon wrasse, yellow-masked angelfish, bumphead parrotfish, tomato anemonefish and barramundi, as well as lots of turtles that still come ashore in this area to lay their eggs.

Due to the remoteness, not many liveaboard boats visit these islands and you will be able to enjoy the dive sites without sharing them with tourist hordes.

This limestone pinnacle was named after former Danish Naval Officer, Andreas Richelieu, who eventually became the only foreign born commander-in-chief of the Royal Thai Navy to date, appointed by King Chulalongkorn. One of Richelieu’s tasks was to modernise the outdated Navy charts, and as he had become such an influential and important figure, this potentially hazardous-to-ships rock that poked out from sea at low tide, east of the Surin Islands, was eventually named after him.

Barely breaking the surface at low tide, this horseshoe-shaped outcropping slopes steeply to a sandy bottom at 18 to 35 meters (60-120 Ft). This site offers great diversity for such a small and isolated spot. It also offers excellent multi-level diving and, because it’s a high-profile reef, there are always sheltered areas to hide from the current.

The marine life is prolific and includes amongst, many other things; pharaoh cuttlefish, large octopuses, all 5 varieties of anemone fish of the Andaman Sea, a variety of moray eels, ornate ghost pipefish, smashing mantis shrimps, harlequin shrimps, tigertail seahorses, Spanish mackerel, frogfish, many schooling snappers and occasional sightings of manta rays and whale sharks.
