Richelieu Rock Diving Adventure Package on a High-Speed Catamaran

The horseshoe-shaped reef discovered by Jacques-Yves Cousteau on his way to the Similan Islands is known for its purple corals (it reminded Jacques Cousteau of Cardinal Richelieu´s purple robe) as well as diverse marine life ranging from small fish and harlequin shrimp to large pelagics like whale shark, manta ray, barracuda and grouper. The pinnacle falls steeply to the surrounding sand bottom at a maximum depth of 35 metres. The south side is a bay with a slope that gently falls to the deep, while the rest comprises sheer walls, groups of rocks and numerous small caves that are home to various marine life.

The majority of corals are colourful soft corals jostling against the wall, accompanied by huge sea fans, hard corals and sea anemones. Covered with colourful soft corals and sea fans, the group of rocks to the northwest host some spectacular species.

Due to the large scale of Richelieu Rock, it is not possible to explore the whole site in one dive. You should plan at least two dives here. Enter at the southeast mooring line and then take the left or right side depending on the current. Ascend with caution, when finishing every dive use a surface marker, swim away from the pinnacle and surface slowly, looking for boat traffic all the time.

Amazement awaits divers in every square metre of Richelieu Rock. Slowing down your pace gives you the reward of a chance to meet rare, camouflaged species. Always keep an eye over your shoulder in case of passing Whale Shark.

Without doubt this is ¨The Highlight¨ during any of our liveaboard trips with The Manta Queen Fleet.
