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 Surat Thani
Surat Thani is the mainland transport hub for the Gulf islands, with an airport, a railway station at Phun Phin and bus links to Krabi and Bangkok. Most island tickets combine a bus to Donsak pier with the ferry, and a slow night boat leaves from the town pier.
Combined bus + boat tickets from the airport or train station are the simplest option: the bus waits for the ferry connection.
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.
