Diving Koh Lanta means to experience some of the most spectacular diving in Thailand. The warm waters, great visibility, vivid colours and range of dive sites mean that whether you want to learn to dive, or are a certified scuba diver already, you’re sure to find plenty to enjoy on every dive you make.
The island is perfectly located to reach some of the best dive sites in Thailand and is the closest departure point for world-class dive sites Hin Daeng & Hin Muang. The most popular dive sites include Koh Haa, Koh Phi Phi (in particular the Bidah Islands), Shark Point, Anemone Reef, King Cruiser Wreck, Hin Daeng & Hin Muang. Some dive centres also visit Koh Rok and the Southern Islands (Koh Kradan, Koh Mook, Koh Wean, Koh Cheuak and Koh Ngai).
Koh Haa In Thai means ‘5 Islands’ and there is good diving around each island. There are about 12 dive sites here. The central lagoon area is perfect for snorkelers and divers alike and provides great macro and juvenile marine life. More advanced divers can explore the underwater caverns and chimneys at the other islands. Koh Haa has better year-round visibility than other dive sites closer to the mainland. Max depth 50m, visibility 15-35m. Island 3 has a white sandy beach and you can even climb to the top for some cliff jumping off the other side. After you’ve jumped, climb back up through the secret lagoon.
Koh Phi Phi
There are close to 30 dive sites around Ko Phi Phi, the best being the Bidah Islands just south of Phi Phi Ley. The huge towering cliffs make this an atmospheric place to visit and there is a huge diversity of coral and marine life at these sites. Phi Phi dive sites are famous for spotting leopard sharks and huge gorgonian sea fans. Max depth 30m, visibility 3-25m.
Named after the leopard sharks that are often seen resting on the sandy bottom, Shark Point is a group of underwater pinnacles about half way between Phi Phi and Phuket. This site has some of the most abundant soft corals in Thailand and is home to literally thousands of fish and other marine species. Max depth 28m, visibility 3-25m.
Anemone Reef is located about 600m from Shark Point. This shallow pinnacle is completely covered in anemones and is home to a huge variety of macro life. Look for many different species of moray eel, ghost pipefish and seahorses. Max depth 25m, visibility 3-20m.
King Cruiser Wreck
A passenger ferry sank in 1997 close to Shark Point and Anemone Reef. The steel wreck has now evolved into a fantastic natural reef and is home to a huge variety of marine life. The wreck is 85 m long by 35 m wide, and has four decks with large walkways and windows. The wreck is completely covered in scorpionfish (be careful where you put your fingers!) and lionfish, and is home to enormous schools of trevally, batfish, pufferfish and snappers. There is a huge turtle that lives inside – you can often spot him as he comes towards the surface to breathe. The depth, together with the frequent strong currents, makes the diving here unsuitable for beginners. Max depth 33m, visibility 3-15m.
Hin Daeng / Hin Muang
These two submerged pinnacles are the deepest dive spots in the area. They’re quite some distance from Koh Lanta, but well worth the journey as they are world-class dive sites and offer some of the best opportunities to look for manta rays and whale sharks. Even if the big stuff doesn’t make an appearance, there’s a huge variety of life to see. You need some dive experience before taking a trip out to these dive sites as the currents can be quite strong. Max depth 60m, visibility 5-40m
