Ko Lanta Yai is the largest inhabited island of the Ko Lanta island group in Krabi province, southern Thailand, and is a well-known tourist destination for beach stays and island access. It combines low-density resort areas, long beaches and local fishing villages.
Main visitor facilities cluster around the northern settlement of Saladan, which functions as the ferry port and service centre, while the southern end of the island is part of the Mu Ko Lanta National Park, protecting beaches and reef areas. The island is popular for relaxed beach tourism, snorkeling trips and as a base for exploring nearby islets.
Historically the island developed from fishing and local trade into a tourism destination from the late 20th century, with gradual expansion of accommodations and infrastructure tailored to international visitors. Conservation measures at the national park and local planning influence development along the coast.
Ko Lanta Yai lies off the Andaman coast of southern Thailand in Krabi province; the island is reachable by ferry from the mainland and other islands and features a mix of sandy shores, coastal roads and low-lying interior.
- Transport and size: The island is the largest of the Lanta group in Krabi province and is served by regular ferries and road links that make it a popular base for multi-day stays and island-hopping trips.
What to See #
- Saladan (main town): Saladan is the main settlement and ferry port at the northern tip of the island, providing accommodation, restaurants and connections to the mainland and other islands.
- Mu Ko Lanta National Park: Mu Ko Lanta National Park occupies the southern tip of the island and adjacent islets, protecting beaches, reefs and a lighthouse area popular with visitors.
How to Get to Ko Lanta Yai #
Ko Lanta Yai is reached by road and short ferry crossings from the mainland in Krabi Province. From Krabi Town or Krabi Airport you can take regular minibuses, local buses or drive south on Highway 4 toward Saladan/Ko Lanta; the journey typically takes around 2-3 hours including the short car ferry crossing that links the island with the mainland. Most services terminate at Saladan Pier (the island’s main town); from there the island’s beaches and villages are reachable by taxi, motorbike or local songthaews (short rides of a few kilometres).
Tips for Visiting Ko Lanta Yai #
- Use Saladan as your arrival point and base - it's the island's main pier and services hub, which makes onward transfers, rentals and early-morning departures easiest to arrange.
- Visit quieter beaches and the national park at the southern tip (Lanta Old Town and Mu Ko Lanta National Park) in the late afternoon for sunset and far fewer day-trippers than the central beaches see during the day.
- Rent a scooter or arrange a driver for a half-day to explore inland and the island's viewpoint lighthouses; many visitors stick to the north coast and miss scenic outlooks and the old wooden houses of Lanta Old Town.
