There are dozens of islands off the Krabi coast. Of these, 15 make up the Mu Koh Lanta Marine National Park, which covers about 135 sq km across four main island groups – Koh Lanta Yai and Koh Lanta Noi, Koh Muk, Koh Rok Nok and Koh Rok Nai, and the Koh Ha group of islands.
The most tourist facilities are found on Koh Lanta Yai; there are numerous bungalow resorts and even a couple of luxury spa and resorts, and even more on the way.
The island is around 25km long, with a hilly central section and a string of superb sandy beaches along its western coastline. The main hub of activity on the island remains at the northern port of Saladan. Here you will find a post office, clinic and banking facilities. There is also a nice selection of restaurants and, of course, a number of the island’s dive operators.
The west coast of the island is where all the beaches are
The diving to the south of Koh Lanta and the adjacent islands is exceptionally good. This is regarded as one of the best areas in Thailand. There’s a great variety of walls, fringing reefs, caves and a wreck to explore around the offshore islands, islets and rocks.
Marine life is abundant, with a healthy cross-section of reef species and pelagics. Only the local operators and a few from Krabi, Koh Phi Phi and Phuket currently utilise these sites, so they remain uncrowded.
