Top Dive Sites
Richelieu Rock: Thailand’s best dive site, bar none. A stunning array of soft corals and spectacular stampeding marine life.
Koh Bon: Thailand’s manta ray hotspot, with plenty of other things to see if the mantas don’t show up.
Koh Bon Pinnacle: is a deep dive site that feels utterly remote – and where anything could show up out of the blue.
Koh Tachai: is one of the Similan Islands’ best dive sites but also one of the most volatile. Massive fans, huge schools of fish, maybe manta rays – it’s all to play for.
West Of Eden: A big boulder site with spectacular outsize fan corals, beautiful soft corals and the promise of full fish activity, West Of Eden is an archetypal Similan Islands dive site.
Ao Suthep, Surin Islands: is beautiful hard coral garden in the Surin Islands, often visited by Similan island diving liveaboards and accessible by snorkellers visiting the Surin Islands too.
Boulder City: A dramatic deep water Similan dive site, Boulder City needs the right conditions to explore as it’s exposed to wind and wave from all sides.
Shark’s Fin Reef: A dramatic block of rock rising out of the sand, Shark’s Fin Reef is one of the Similan Islands’ most exciting sites.
Hideaway Bay: Two Similan Islands dive sites in one location, Hideaway Bay and Tuna Wreck can be experienced in a single dive.
North Point: is another of the Similans’ signature big boulder sites, with huge great rocks rising out of the white sand.
Three Trees: named after the three trees directly above the dive site on Similan Island 9, is a big wide white sand channel with some awesome corals and fish encounters.
Christmas Point: One of the signature Similan Islands big boulder dive sites, Christmas Point’s huge rocks have been shaped by the tides over hundreds of years.

Useful information
Similan Islands
Best time for diving
Mid-October - May is the optimum diving season on the Andaman coast (west coast). From early December until late April you can usually expect clear skies nearly every day. On average, you can expect 20 meters of visibility at The Similan Islands throughout the diving season.
Due to the likelihood of extreme weather during the monsoon months, the local authorities close the marine parks from May 16th until October 14th every year. Therefore the Similan diving season is from October 15th to May 15th.
About temperatures
Air: throughout the year, temperatures range from 25°C to 34°C with April through May being the hottest month and January the coldest
Sea: between 27°C - 29°C all year round, there are times when it drops to the mid or even low 20s, but in general these are rare or temporary occasions.
Wetsuit Recommendation
We recommend a 3 mm wetsuit year-round.
Diver requirement
Suitable for all levels. You can find out more information about diving in Similan Islands here : Similan Islands
