Similan Richelieu Rock Diving Cruise

FROM SIMILAN ISLANDS TO RICHELIEU ROCK DIVING SITES

To help understand the location of all the Similan dive sites, we have separated the areas into two.
 
► SIMILAN ISLANDS which has 9 un-inhabited islands.

► SURIN ARCHIPELAGO which is situated around 30 to 40 miles north of the Similan Islands and is made up of Koh Bon, Koh Tachai, the Surin Islands and the famous Richelieu Rock Diving site.

THE SIMILAN ISLANDS ARCHIPELAGO

The worldwide reputation of the Similan Islands is due to the area having the richest variety of marine life in Thai waters and together with the Hin Daeng and Hin Muang areas, which are situated to the south of Phuket, there are around 500 species of hard and soft corals, and an even higher amount of pelagic and coral fish with sizes that many other sites struggle to match.

The Similan Archipelago is also home to the biggest fish in the world, the whale shark, which together with manta rays, leopard and white tip sharks are regularly encountered during the peak season.

Aside from the aquatic realm, the seabed topography is truly fantastic: huge granite boulders covered with coral lie together all the way from the surface to 40 meters and beyond, providing lots of exciting swim throughs, canyons, archways and caves, some perfect spots for U/W pictures and video effects.

SURIN ARCHIPELAGO & RICHELIEU ROCK DIVING

The Archipelago is composed of the Koh Bon, Koh Tachai, Surin Islands and Richelieu Rock diving sites.

Koh Bon with its breathtaking drop-off where large sting rays are encountered, recently, a manta ray decided to appear here during the lunch break and spent 20minutes swimming in 5 meters of water (true story!!…).

Slightly further north lies Koh Tachai, with its reef in the middle of the sea and depths up to 35 meters, covered with granite boulders, sea fans and large schools of pelagic.

The Surin Islands offer a large number of dive sites with coral gardens, fields of granite boulders and therefore a wide and rich amount of fish and coral species.

Richelieu Rock diving is considered from many divers as the must of Thailand.
The famous Richelieu Rock, the origin of the name is not clear; however some say it was named after the red colour of Cardinal Richelieu‘s robe, due to the red to purple colours of the soft corals on the reef. Others claim it was named after a Danish naval officer who became a Siamese admiral in the Royal Thai Navy. There is enough on show here to justify several dives; Sand sharks, (leopard, nurse) big sting rays and other pelagic such as barracuda, tuna, mackerel, which are a common feature and what about that whale shark waiting for you to take a swim with? Only a few short years ago, two of them where actually “residents” of the islands, don’t miss the chance of this unique experience

We will guide you through the best sites, swim-throughs, coral reefs, drop-offs and pinnacles the Islands have to offer, but we won’t take you to the most crowded!
