Koh Samui and Koh Lanta are on opposite coasts of the Thai peninsula, so there is no direct sea route. These tickets combine a road transfer across the peninsula with a boat, usually via the Donsak or Surat Thani piers for the Gulf islands, and the times shown are for the whole trip door to door. Expect most of a day: the quickest listed takes 7h 30m, and the operator times the van to meet the ferry.

Good to know before you go
Leaving Koh Samui
Koh Samui has its own airport and is the starting point for most trips to Koh Phangan and Koh Tao. It has several piers, and the right one depends on the operator, so check the departure pier on your ticket, not just “Koh Samui”.
Bangrak and Maenam are 10–20 minutes from the airport; Nathon is on the far side of the island. Allow for traffic in Chaweng.
Arriving in Koh Lanta
Koh Lanta is a long island with a string of quiet beaches down its west coast. You can drive here by van using one short car ferry to Koh Lanta Noi and a bridge to Lanta Yai, or arrive by boat at Saladan, the northern village where all passenger ferries and speedboats dock.
From November to April, speedboats from Saladan link Lanta to Koh Ngai, Koh Mook, Koh Kradan and Koh Lipe. In the rainy season most of these stop.
Weather and season
Weather runs to a different clock from the Andaman: the Gulf is usually calmest from February to August. Expect rain and rougher crossings from October to December.
