One of the Best Dive Sites in Thailand:  Richelieu RockScuba diving Richelieu Rock thailand
Many consider this horseshoe shaped rock near the Surin Islands in the Andaman Sea Thailand's best scuba diving site.  Dive pioneer, Jacques Yves Cousteau, with the aid of local fisherman, discovered this gem sitting about 200 kilometres/124 miles northwest of Phuket and 70 kilometres/43 miles from Khao Lak.

Richelieu Rock's sheer variety of marine life- including whale sharks- attracts divers from around the world. Divers will be entranced by circulating barracuda, large grouper, and thousands of smaller fish circling around the pinnacle. Although the large pinnacle is the primary attraction, divers will also find smaller crests that peak from 3-10 metres/10-33 feet below the surface.  Because the dive site tends to concentrate the area's marine life, Richelieu's Rock is also an excellent place to see larger predators.

Other varieties of marine life that inhabit the corals in this area include, schooling bannerfish, snappers, lionfish, moorish idols, titan triggerfish and shovelnose rays. Divers may also see bearded scorpionfish, stonefish, moray eels, seahorses, pipefish, Sshrimps, crabs, cuttlefish and nudibranchs.

Whether you're a macro enthusiast or a junkie for seeing big stuff underwater, Richelieu Rock has something for you. Because it is so popular, you can easily hop a dayboat or liveaboard out of Khao Lak or Phuket.

Phuket and Southern Thailand
Considered a premier tourist destination, Phuket is the country’s largest island and home to the region’s largest liveaboard fleet. Off of Krabi--a southern province on the Andaman Sea- divers can visit rock formations or head to the Phi Phi islands that comprise Koh Phi Phi Marine National Park.

Further south, around Koh Lanta, divers can enjoy can both enjoy wall dives and swimming among fringing reefs. Hin Daeng and Hin Mouang, both sites to the open ocean, feature encounters with Manta Rays and Whale Sharks.  

Another popular dive site just 25 kilometres/ 16 miles east of Phuket is the Shark Point Marine Sanctuary. With a name like Shark Point, you'd expect to see sharks and you won't be disappointed by the Leopard Sharks resting on the sandy bottom. Visibility ranges from 10-20 metres/33-66 feet and the high density of fish makes the diving a fantastic experience. Barracudas, gorgonian sea fans, Leopard Sharks, and plenty of small fish can be found here. Divers of all levels will enjoy the wreck of the 85-metre/ 279-foot King Cruiser  passenger ferry.
