How to Get to Don Sak

Don Sak is the mainland ferry port for the Gulf islands and is reached by road from Surat Thani or by combined bus+ferry tickets from Bangkok. Trains to Surat Thani plus a short transfer are a common route for budget travelers.

Samui Airport (USM): If your destination is Koh Samui you can fly directly into Samui Airport and then use local ferry/taxi connections; Don Sak itself is on the mainland and is mainly accessed via Surat Thani town or airport transfers rather than direct international flights.

By Train & Bus
