Activities on Koh Lanta Island:
Scuba Diving the Andaman Sea

Dive operators on Koh Lanta  have the best access to the great Southern Dive Sites of Koh Phi Phi Ko Ha, Ko Rok, Hin Daeng and Hin Muang.

The 3 main dive sites around Phi Phi Island are Shark Point, Anemone Reef and the King Cruiser Wreck, all in easy reach for dive operators based in Krabi's Koh Lanta

While dive operators in Phuket include the Racha Islands as one of their main daytrip destinations, however, they are too far away from Koh Lanta  and will not be visited by any of the local shops

Any diver that wants to spend quality time visiting Southern Thailands greatest dive sites should base themselves in Koh Lanta.

The map above lables 5 different Dive Areas. These Areas are:

1. Shark Point, Anemone Reef & the King Cruiser
2. The Phi Phi Islands & Ko Bida (Nok & Nai)
3. Ko Ha (or the Five Islands)
4. Ko Rok (Nok & Nai)
5. Hin Daeng / Hin Muang (Red & Purple Rocks)

The map also shows the relationship
between the different resorts in the Krabi Province and the dive destinations.

There are more than 20 dive operators on Koh Lanta and you should choose a reputable dive school. The following ones are the longest existing dive operators on Koh Lanta and offer daytrips and liveaboard dive safaris to destinations described within this website as well as PADI Dive Courses from beginner level all the way through to Instructor Development Courses.

When the conditions are right,
dependent on such factors as weather, tides, thermoclines and the dive tour operators themselves, the diving in Southern Thailand can be truely spectacular so be prepared for some fantastic diving.

The Dive Sites

Bida Nok & Bida Nai

There are two rocks called Bida Nok and Bida Nai that lie south of Phi Phi Island and can be reached within 1.5 hours from Ko Lanta. This is the place to watch for schools of ocean going pelagics like tuna and mackerel and see some leopard and possibly nurse sharks.

Both islands offer a great variety of hard and soft corals and plenty of caverns and swim-throughs where wall and cave dives can be practised. Visibility is between 5 and 25 metres.

Maya Bay

Maya Bay is one of the most beautiful lagoons to imagine and belongs to the south isle of Phi Phi. It is surrounded by rock walls that shelter a white sandy beach.

Under water, hard and soft corals, invertebrates and coral fishes can be found. Visibility is between 5 and 25 metres.



Sharkpoint, Anemone Reef & the Kingcruiser Wreck

Sharkpoint consists of 3 pinnicles jutting out of a fantastic coral garden. Numerous scattered, rock formations give shelter to innumerable tropical fishes and some leopard sharks. Visibility is between 5 and 25 metres. The main feature of the Anemone Reef is in the name already.

Strange rock formations like canyons, overhangs and ravines make it the ideal place for a beautiful dive. Close by to Sharkpoint and Anemone Reef lies the wreck of the King Cruiser, a catamaran passenger ferry with a length of 85 metres.  It sank in 1997 and can be enjoyed at depths of 12 to 30 metres. Visibility here ranges between 5 and 25 metres.

Hin Bida

Hin Bida is an underwater reef about 1 hour west of Ko Lanta by boat.  From November to December leopard sharks can be observed during their mating game, while whale sharks are passing the reef during March and April.

As the dive site is quite shallow, visibility is not always good.

Ko Ha

Ko Ha is a group of five limestone rocks rising out of the water 45 meters deep. They are reached within 1.5 hours from Ko Lanta and offer steep walls dives, small caves, tunnels, canyons and two gigantic caverns.  Where the walls fall down to 30 metres, whale sharks have been observed. Visibility is between 10 and 30 metres.

Ko Waen

Ko Waen fascinates by a variety of rock formations and a real underwater road network. A cave system washed into the rock reminds one of Swiss cheese.

Visibility is between 5 and 25 metres.


Ko Rok Nok & Nai

A journey of 2.5 hours takes you to the twin islands of Rok Nok and Rok Nai. A real underwater coral garden with countless coral fishes, immense barracuda swarms, turtles and lobsters can be found there. The beaches are among the most beautiful South Thailand has to offer. Visibility is between 5 and 25 metres.

Hin Daeng & Hin Muang

Lastly you have the submerged rocks of Hin Daeng and Hin Muang, with depth of up to 70 metres and steep walls, that are overgrown with soft corals and anemones. Undoubtedly one of the best diving spots in Thailand. Grey reef sharks, tuna, mackerel, barracuda and the queen of pelagic fishes, the manta ray, are regularly spotted. Although the whale shark population has declined in recent years, several encounters are recorded every year. Visibility is between 10 and 40 metres.
