Locals call it "Plo Nam" Rumor has it: discovered by Jaque Cousteu.
The best dive site in Thailand, but the viz is not excellent (Especially at large plankton blooms) (generally around 10m). Sealife is exceptional, large fish shoals Barracuda, Snapper, Trevally, also invertebrates...
Richelieu Rock has everything- Micro and macro. Porcelain crabs, Tiger Tail Sea Horses, Pipefish, Nudis, Harlequin Shrimp....
very little predator sharks
You can expect to see whale sharks (from february to may)
Whaleshark and Mantas both frequent the area. Best times are beginning and end of dive season when plankton blooms are highest.

Thailand's best dive site! - Richelieu Rock is the best dive site in Thailand. A horseshoe-shaped reef that just breaks the surface at low tide, and always full of fish! If there's current, you can always find shelter. Possible to dive 4 times in one day (but no night dive) without getting bored!

Great site - Although each site in Andaman sea has its own uniqueness, there is no doubt this is the best, with great variety and concentraion of small creatures and many fish shoals. Requires at least few dives

new to daily discover - with MV Zcubatech, operated by Signscuba. Best divesite Thailand has to offer. A bit exposed, can be a bit rough eventually. On calm days, sunlit, a dream! Mainly high season between october and may,.
