Koh Lanta Dive Sites

Some of Thailand's Best Diving

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

All of these dive sites are surrounded by extensive coral reefs and are home to a huge variety of marine life.

The dive sites around Koh Lanta also include Koh Bida Nok and Koh Bida Nai, 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.

Check out some of Thailand's best diving below:

Koh Haa One

The Koh Haa Yai Islands are an archipelago of 6 islands lying around 25 km to the south west of Dive & Relax on Koh Lanta. Due to the usually good visibility, wide range of underwater geology, extensive coral reefs and diverse marine life, these 6 islands are one of the most popular dive destinations in Krabi Province.

Koh Haa Lagoon

Due to the usually good visibility, wide range of underwater geology, extensive coral reefs and diverse marine life, these 6 islands are one of the most popular dive destinations in Krabi Province.

Koh Haa Yai

Koh Haa Yai is the largest of the 6 islands, and also home to The Cathedral, a huge cavern with spectacular stalactite formations and several swim-throughs.

Koh Rok - Lak Siam

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

Koh Rok - Hin Ngam

Hin Ngam is located at the south west part of Koh Rok Noi and is a rocky dive site with an abundance of hard and soft corals.

Koh Rok - Pak Rong

Pak Rong is the channel between the two Koh Rok islands, with the rocky bottom providing a home to hundreds of hard and soft corals.

Hin Daeng

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

Hin Muang

Dive Hin Muang by speedboat from Koh Lanta, with a chance to see whale sharks and giant oceanic manta rays at one of Thailand's best dive sites.

Koh Bida Nok

Of all the islands around Phi Phi, Koh Bida Nok and has by far the most extensive corals and marine life diversity.

Koh Bida Nai

Lying just to the north of Koh Bida Nok is the little sister, Koh Bida Nai. Another favourite of divers visiting the area.

Hin Bida

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

Phi Phi - Palong

Palong Bay is just north of the famous Maya Bay on Phi Phi Leh, where we hope to spot black tip reef sharks and hawksbill turtles.

Phi Phi - Viking Bay

To the north east of Phi Phi Leh is Viking Bay, together with the two dive sites Table Coral City and Artificial Reef which are often combined to a single dive due to their close proximity.

HTMS Kledkaeo Wreck

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

Hin Klai

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

Shark Point as a spectacular Marine Sanctuary comprising three pinnacles running roughly north to south, located between Phi Phi and Phuket.

Anemone Reef

Covered with countless anemones feeding on the currents, Anemone Reef begins around 4m, sloping down onto the sandy seabed at around 26m.

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.

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.
