Krabi Province has the largest range of dive sites available in Thailand, offering beautiful diving and snorkeling with plenty of succulent soft coral, limestone outcrops and an enormous diversity of marine life. Although the region was struck badly by the 2004 Tsunami disaster, the area has recovered impressively and divers are coming back in flocks.
The main diving bases for the many sites in the Krabi area are Ao Nang and Railay beaches on the Krabi mainland, Phukets Chalong Bay and the Islands of Phi Phi and Ko Lanta. Ao Nang beach has the highest concentration of Dive centers and accommodation, as it has access to all the sites at Phi Phi, Shark Point marine sanctuary, Hin Daeng and Hin Muang, the Ko Ha Islands and also a group of 10 small island dive sites in Ao Nang Bay.
Phi Phi Island attracts a younger crowd of revellers but offers easier access to the dive sites around it's shores. The island has two remarkable limestone crops divided by a narrow flat isthmus and it is there where most of the visitors stay. Ko Phi Phi has an abundance of succulent coral and colorful schools of fish.
Shark Point Marine Sanctuary, which lies directly between Krabi, Phi Phi and Phuket, is a popular group of 3 dive sites which are usually all dived together in a single trip. The King Cruiser Wreck is the remains of an 85 meter long twin hulled passenger ship which sunk in 1997 after running aground on Anemone reef.
The Anemone reef itself is a unique dive site with a massive limestone pinnacle soaring 30 meters from the seabed to just 4 meters beneath the surface. The site is well-known for its abundance of sea anemones that cling to every surface while attracting enormous schools of fish. Different types of fish to be seen include schooling reef fish, trevally, snappers, groupers and colorful clown fish, along with larger game-fish like tuna and barracuda as well as the occasional leopard shark.
The third site is the site which gives the group it's name -Shark Point. This is a reef that comprises three pinnacles, the largest of which breaks the surface appearing as a barren rock outcropping. The reef is home to a delightful abundance of colorful soft corals and vibrant sea fans that decorate the limestone pinnacles, giving hoe to many Morays, Sea Horses, schooling reef fish and larger pelagics.
In the south of Krabi is Ko Lanta, with many dive shops in and around the main tourist areas of Saladan Town and Klong Dao beach. Although it has limited access to the northern sites in Krabi, it is close to some of the best dive sites in Thailand (ranked in the top ten in the world); the underwater pinnacles of Hin Daeng and Hin Muang, and the Ko Ha group of Islets. Although these sites are reserved for the more experienced diver, with strong currents, the deepest wall dive in Thailand, and large underwater caverns to explore, the rewards are tangible with frequent visits by Whale Sharks and Manta Rays, an enormous variety of fringing reefs, as well as pelagic and reef fishes.
