The crossing is part of the trip: you leave the mainland behind and watch the wooded hills of Koh Samui rise out of the Gulf of Thailand. Most journeys combine a road transfer to a pier with a ferry, so the choice comes down to which ticket bundles both.
Surat Thani to Koh Samui by Car Ferry
Raja Ferry sails from Donsak pier on the mainland to Lipa Noi Pier on Koh Samui every hour from 04:00 to 19:00, and the crossing takes about 1 hour 30 minutes.[1] The fare is 220 THB.[2] You arrange the road transfer from Surat Thani to Donsak separately.
Combined Tickets and Speedboat
Seatran Discovery lists bus and ferry transfers between Surat Thani, Donsak and the Koh Samui piers.[3] On booking platforms a speedboat crossing from Surat Thani to Koh Samui takes about 2 hours and costs about 700 THB (November 2026).[4]
Surat Thani to Koh Samui by Private Transfer
A private transfer takes you from the airport, the train station or your hotel in Surat Thani to the pier and often on to the island. Vans seat 9 to 10 passengers, which suits families and groups, and prices on booking platforms start at about 650 THB (November 2026), depending on the vehicle and the pickup point.[4]
Tips for Traveling from Surat Thani to Koh Samui
- Check the pier: Make sure your ticket names the pier you need on Samui, because the island is large.
- Book ahead in high season for speedboat and combined tickets.
- Allow slack in bad weather: Heavy rain or high winds can delay or cancel crossings, so keep a buffer before a flight.
