Similan Dive Sites
Richelieu Rock is one of the most famous dive sites of Thailand. Richelieu Rock is an isolated pinnacle to the east of Surin Islands north of Koh Bon. The site is marked by the top of the pinnacle which is 1 meter above sea level during low tide, and disappears underwater during.
Due to the diversity of small and large creatures, Richelieu Rock is a paradise for underwater photographers. Ghost pipefish, frogfish, harlequin shrimp, seahorses, pipefish are some of the smaller marine life that can be spotted here. Also, divers have often encountered cuttlefish mating. In addition, plenty of anemone fish species, particularly tomato clownfish, are regularly sighted. Different types of moray eels such as giant moray, zebra moray, and white-eyed moray are common.
Pelagic fish swarming around the smaller outcrops include chevron barracuda, rainbow runners, and plenty of bigeye trevally, fusiliers and snappers. In addition, giant groupers resting on the sand floor are a common sight. Lastly, this site is famous in Thailand for being the hotspot for encounters with both whale sharks and manta rays.
Due to the large scale of Richelieu Rock, it is not necessary to explore the whole site in one dive. You should plan at least two dives here. Enter at the southeast mooring line and then keep to the left or right side depending on the current. Ascent with caution. When finishing every dive, use a safety sausage, swim off the pinnacle and surface slowly.
Beware of the boat traffic. Amazement awaits divers in every square meter of Richelieu Rock. Slowing down pace gives you the reward of a chance to meet rare, camouflaged species. Don’t forget to take a look out to the surrounding blue waters from time to time, as a whale shark may wander past. You just never know!
