Dreamy Richelieu Rock

---

Richelieu Rock is widely regarded as the best dive site in Thailand, and for many divers, it represents the highlight of any Andaman Sea itinerary. Located far from the mainland, this iconic, horseshoe-shaped rock rises dramatically from the open ocean. However, its rocky tip is visible only during low tide, offering little hint of the extraordinary underwater world hidden below the surface.

As shown in the video above, Richelieu Rock truly stands apart from other dive sites. From the moment you descend, the site begins to reveal its complex and colorful underwater landscape. In particular, the rock is covered in soft corals, sea fans, and anemones, which together create a vibrant backdrop for an incredible variety of marine life. Moreover, strong currents bring nutrient-rich waters to the area. As a result, both small and large species thrive here throughout the year.

Because of this unique underwater topography, Richelieu Rock provides shelter for an extensive range of marine creatures. For macro enthusiasts, entire dives can be spent searching for harlequin shrimps, ghost pipefish, seahorses, and nudibranchs. At the same time, wide-angle divers are rewarded with swirling schools of fish, including trevallies and barracudas. Most famously, Richelieu Rock is known for sightings of manta rays and the ever-graceful whale shark. Consequently, every dive feels full of anticipation.
