潜点: Richelieu Rock

关于 Richelieu Rock

Richelieu Rock, often celebrated as Thailand's premier dive site, is a majestic, isolated pinnacle located within Surin National Park in the northern Andaman Sea. Situated about 18 km east of the Surin archipelago and roughly 70 km northwest of Khao Lak, this unique site emerges above the surface only at low tide. The rock itself forms a distinctive horseshoe shape, featuring a central limestone pinnacle complemented by numerous smaller rock outcrops, all teeming with life. Its topography includes shelves, ledges, cracks, crevices, and small caves, providing a varied and dynamic underwater landscape. Jacques Cousteau reportedly named it after Cardinal Richelieu, inspired by the vibrant purple-red soft corals that adorn the rock, reminiscent of the cardinal's robe. This site boasts exceptional biodiversity, catering to both macro enthusiasts and those seeking pelagic encounters. The rock face is blanketed in an abundance of purple soft corals, vibrant hard coral bommies, and extensive anemone gardens. Divers frequently spot a huge array of smaller marine life such as porcelain crabs, tiger tail seahorses, various pipefish, robust ghost pipefish, mantis shrimps, harlequin shrimp, frogfish, leaf fish, and numerous nudibranchs. The deeper sections feature black coral bushes and gorgonians, offering shelter to an even wider array of creatures. The isolation of Richelieu Rock, coupled with tidal current upwellings, creates a rich feeding ground that attracts large schools of fish and substantial pelagic animals. Visibility here can range from 10-15 meters to an impressive 35 meters on clear days, with lower visibility often indicating higher plankton concentration – a key draw for larger filter feeders. Currents can be strong and changeable, making it an advanced dive despite shallow areas suitable for Open Water certification. It is frequently included in Similan Islands liveaboard itineraries, but day trips from Khao Lak are also popular. The dive experience at Richelieu Rock is multi-level, with depths reaching beyond 30 meters, offering ample opportunity to explore its diverse ecosystems.
