Koh Lanta dive sites
Koh Lanta Diving | Koh Lanta diving tours and dive trips
The dive sites around Koh Lanta vary in characteristic. Koh Lanta's rich waters offer sandy coves, coral reefs, limestone rock outcrops, rock reefs, seamounts and pinnacles, undersea caverns and tunnels and sunken ships.
Hin Daeng and Hin Muang
The twin peaks of Hin Daeng and Hin Muang are rated in almost the world top 10 lists of dive sites. Situated just 20 km from Koh Rok, the pinnacles offer steep walls covered with pink, purple and red coral and house an incredible variety of marine life.
Being the lone coral outcrop in deep open sea, the site attracts large numbers of pelagics, and very large Jacks, Fusiliers, Tuna and Barracuda can be seen. Schools of Grey Reef Sharks can be curious and will often approach divers for a closer look. The dive site has one of the world's highest incidences of whale shark sightings.
Koh Ha is a group of five islands separated by deep water channels. This dive site with easy access from Koh Lanta offers six different places to dive, with good visibility.
Marine life here is plentiful with all the regular visitors including morays and nudibranchs with the bigger tuna, jacks and trevally hunting in the deeper waters.
There is a series of caves at the largest island, Koh Hah Yai, where natural light filters into a large underwater chamber. The entrance is at about 12 meters and you can actually surface inside to view some spectacular overhanging stalagtites.
Koh Rok actually consists of two islands Koh Rok Nai (inside) and Koh Rok Nork (outside).
The two uninhabited islands have some of the most stunning beaches in Thailand and are popular with day tripping snorkelers. Diving here is also very shallow but this results in good visibility, and an abundance in colorful marine life.
Koh Kradan Wreck
Koh Kradan is a small island to the southeast of the southern tip of Koh Lanta.
A Japanese destroyer sunk just off the coast in 1944 following an air raid. She now lies broken in two below a thermocline in around 25 meters of water.
Visibility is dramatically reduced below this thermocline at 15 meters or so and the wreck is still draped with fishing nets so a dive light and knife are essential. Seahorses are often spotted hiding in crevaces along the wreck.
