This site is what put the Andaman Sea on the map. Nearly ten miles east of the Surins, this site is widely regarded as world class. The reputation is well deserved, as marine life here compares favorably with the best sites anywhere in the world.

Almost entirely submerged, Richelieu consists of one large rock pinnacle and several smaller ones, sloping steeply up from a surrounding sand bottom at about 33 meters.

Although visibility here is often limited, the abundance and variety of marine life is astounding. Dense colonies of sea anemones cover many of the shallower rock surfaces, providing homes for at least four different species of clownfish. Other invertebrate life includes a wide range of shell fish, a multitude of shrimp, crabs, sea stars and nudibranchs.

Lots of big fish including Snapper, Tuna and Surgeonfish frequent the site. Large Stingrays, Shoveled Nosed Rays, Sand Sharks, Leopard Sharks and the elusive Whale Shark are also commonly sighted here.

Encounters with Whale Sharks is an incredible experience and Richelieu is among the best places in the world to see these animals. Remember, even without a Whale Shark encounter, Richelieu still offers a concentration and divesity of marine life found at few other places; it is a sight not to be missed!
