By Ferry
Ferries run to Ko Lanta from Phuket, Krabi, Ko Phi Phi & Ko Lipe, however only in the high season - from Nov-May.
Ferry tickets can be purchased from the pier, your resort or most travel agents in Phuket, Krabi or Ko Phi Phi. The ferry arrives in Saladan, in the north of Ko Lanta.
If you have already booked a resort, it is normally possible to arrange a pickup from the ferry. Alternatively, it is possible to take a taxi to the south of the island for around 3-400 Baht.
