Koh Lanta Dive Sites

Dive Sites Around Koh Lanta

Koh Lanta is perfectly located close to many of Thailand's best dive sites, including the 6 coral-fringed Koh Haa islands, the beautiful diving paradise at 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 HTMS Kledkaeo Wreck and the submerged pinnacle of Hin Klai, located just east of Koh Phi Phi Leh, both making an excellent addition to the dive sites around Koh Phi Phi and the Bida islands.

All our dive sites range from 30 - 75 minutes by speed boat from Koh Lanta, helping to make Koh Lanta one of the best locations in Thailand for scuba diving, snorkeling, and PADI courses.

Diving Koh Haa

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. The name Koh Haa Yai literally means '5 islands and the big one', with Koh Yai being the largest island (we normally call it Koh Haa Yai) at the west of the archipelago, and the other 5 islands making up the remainder of this divers paradise. Each of the 6 islands are quite different, with most being too big to fully cover in a single dive. This means that we actually have 12+ dive sites/routes around these wonderful islands and we recommend that any diver visiting Koh Lanta should try to make at least two trips to the Koh Haa Islands. When planning dives around these islands is it worth remembering that a dropping tide will generally run north to south, and a rising tide will generally run south to north.

Diving Koh Rok

The two large, coral fringed tropical islands of Koh Rok Nok and Koh Kok Nai are some of the best known islands in the Mu Koh Lanta Marine Park. With white sandy beaches and extensive coral reefs, these beautiful islands are perfect for both divers and snorkelers.

Diving Hin Daeng & Hin Muang

The Hin Daeng and Hin Muang dive sites are two famous rocky pinnacles located in deep water at the far southern fringes of the Mu Koh Lanta Marine National Park. The coral condition at these dive sites is excellent, with a huge abundance and diversity of marine life, and many species not normally found at the other dive sites around Koh Lanta. These dive sites are home to literally millions of fish. Sitting far from mainland Thailand, Hin Daeng and Hin Muang are important cleaning stations for pelagic marine life, including Giant Oceanic Manta Rays and Whale Sharks, which we may see passing by at certain times of year. These dive sites are in open seas and whilst most of the time conditions at these dive sites are great, they are also subject to strong currents, possible rougher surface conditions, and occasional terrible visibility. These dive sites are not suitable for less experienced divers.

Dive Koh Bida

The twin islands of Koh Bida Nok and Koh Bida Nai lie to the south of Koh Phi Phi, and together with Hin Bida, they form The Bida Islands dive sites. Koh Bida Nok is furthest south island in the Phi Phi archipelago, a favourite dive and snorkeling spot for many visiting Koh Phi Phi.

Dive the Phi Phi Islands

The Phi Phi islands are an archipelago of six islands, with the two largest islands of Phi Phi Don and Phi Phi Leh at the center. To the north lie Bamboo and Mosquito Islands, and to the south lie the twin islands of Koh Bida Nok and Koh Bida Nai. The stunning, sheer limestone cliffs topped with untouched tropical jungle, breathtaking turquoise lagoons and a spectacular underwater world have a magical effect on visiting divers.

Dive Shark Point & Anemone Reef

Designated a Marine Sanctuary in 1992, Shark Point (Hin Musang) is located mid way between Koh Phi Phi and Phuket, approximately 50 - 60 minutes from Koh Lanta by speedboat. It is a magnificent dive site made up from three pinnacles running roughly north to south, with the largest pinnacle to the north breaking the surface and supporting a light beacon to warn passing ships of danger.

Dive the HTMS Kledkaeo Wreck

The 382 ton supply ship 861 HTMS Kledkaeo entered service in the Royal Thai Navy in 1956 as a transport support ship until being decommissioned and sunk as an artificial reef close to Koh Phi Phi Leh on 19th March 2014. With a maximum speed of 12 knots, she was laid down as the 47.2m long, 7.7m wide RNoMS Norfrost in 1948 by Pusnes Mechanical Workshop, Arendal, Aust-Agder Norway.

Dive Hin Klai

Just 2 kms east of Koh Phi Phi Leh's Viking Bay lies the submerged and rarely dived Hin Klai (sometimes called Gareng Heng). This gently sloping pinnacle begins at around 6m, dropping to around 13m on the east side and 17m on the west side.

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.
