Good to know before you go
Leaving Donsak
Donsak is a small coastal town east of Surat Thani with the car-ferry terminals for Koh Samui and Koh Phangan. Raja Ferry and Seatran run large vehicle ferries roughly every hour in daytime.
Driving a hire car? Raja and Seatran take vehicles. Check your rental terms allow the car on a ferry.
Arriving in 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.
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.
