Koh Lanta Dive Sites

Explore the Andaman Sea

Koh Lanta is perfectly located close to many of Thailand's best dive sites, including the 6 coral-fringed islands at Koh Haa, the beautiful Koh Rok islands, and Thailand's deepest wall dive, the two pinnacles at Hin Daeng & Hin Muang.

The dive sites around Koh Lanta are home to extensive, healthy, coral reefs and a huge variety and abundance of tropical marine life.

Koh Lanta's dive sites also include Bida Nok & Bida Nai, the submerged pinnacle at Hin Bida, the famous Koh Phi Phi, and the further away Shark Point & Anemone Reef.

We also love diving the super-fishy HTMS Kledkaeo Wreck and the pristine submerged pinnacle of Hin Klai (sometimes called Garan Heng), located just east of Koh Phi Phi Leh, and easily reached from Koh Lanta in just 35 - 40 minutes.

Koh Haa

The 12+ dive sites at Koh Haa are home to extensive coral reefs, a huge variety and abundance of marine life, and often excellent visibility.

We're more likely to see endangered hawksbill turtles diving Koh Rok than any other dive site in the Lanta or Phi Phi marine parks.

Hin Daeng and Hin Muang are possibly two of the most famous dive sites in Thailand, two rocky pinnacles located in deep water at the far southern edge of the Mu Koh Lanta Marine National Park.

Of all the islands and dive sites around Phi Phi, Bida Nok and Bida Nai have some of the most extensive corals and marine life diversity, especially Bida Nok

With the best chance to see leopard sharks, the submerged pinnacle of Hin Bida is one of our favorite dive sites.

Diving @ Phi Phi Palong with Dive & Relax

There are several excellent dive sites around Koh Phi phi Leh, just a 40 minute speedboat trip from Koh Lanta.

Diving @ HTMS Kled Kaeo Wreck with Dive & Relax

The supply ship HTMS Kled Kaeo entered service in the Royal Thai Navy in 1956, and was sunk as an artificial reef off Phi Phi in March 2014.

The rarely dived Hin Klai is a pristine dive site located just 2 km from Phi Phi, a gently sloping submerged pinnacle to around 18m.

Shark Point & Anemone Reef form a spectacular Marine Sanctuary located between Phi Phi and Phuket, teeming with wildlife and healthy corals.

Why Diving from Koh Lanta?

Koh Lanta is fast becoming a diving mecca, possibly one of the best island bases for diving the Andaman Sea.

With a far greater variety and abundance of marine life, the dive sites around Koh Lanta are more healthy, more diverse, and more extensive than any dive sites you'll find in the Gulf of Thailand.

Diving Hin Daeng from Koh Lanta with Dive & Relax

The dive sites around Koh Lanta are easily comparable to the Similan Islands, and in many cases, have better coral condition and more abundant marine life.
