Getting to the Terminal and Understanding the Gates
When you arrive at the Donsak ferry terminal near Surat Thani, you’ll see three lanes/gates:
- Green: Foot passengers (no vehicle)
- Blue: Cars without tickets (buy at the gate)
- Red: Cars with pre‑purchased tickets
If you’ve booked ahead, head straight for the red lane. At the check‑in booth, staff will record your license plate and hand you a boarding ticket. If you haven’t booked, use the blue lane to purchase a ticket on the spot.
Only the driver may stay with the vehicle during loading. All other passengers must disembark and enter via the passenger terminal for safety and efficiency.
Ticket Options and Prices
- Foot passenger: 170 THB per person (children discounted; infants often free)
- Standard car (driver included): 550 THB one way
- Membership (optional): 200 THB for Seatran Member access to the lounge and other perks
You can buy tickets online, at the terminal counters, or from automated machines. If you’re travelling in a group with a vehicle, remember: the driver stays with the car to board, while everyone else walks through the passenger terminal.
Should You Book Seatran Ferry in Advance?
Many travellers wonder whether they need to pre-book the Seatran Ferry from Surat Thani to Koh Samui or if they can simply buy tickets at Donsak Pier. In low season, you can usually purchase tickets at the terminal without any issues, especially as a foot passenger. Ferries run frequently throughout the day, and space is rarely a problem outside major holiday periods.
However, during high season (roughly December to April), Thai public holidays, and long weekends, ferries can fill up—particularly for vehicles. If you’re travelling with a car or motorcycle, it’s strongly recommended to book in advance to secure your preferred departure time and avoid waiting for the next available sailing. Pre-booking also adds peace of mind if you’re connecting from a flight or on a tight schedule.
In short, walk-on passengers in low season can usually buy tickets on arrival, but anyone travelling with a vehicle or during peak travel periods should reserve ahead.

Boarding with a Car on the Seatran Ferry
- Join the designated vehicle lane and wait for boarding instructions.
- Show the ticket issued at the entrance booth—staff will collect it as you proceed.
- Follow the crew’s directions to park on the vehicle deck. Motorcycles and trucks also board efficiently.
- Once parked, the driver should lock the car and head to the passenger decks.
The loading process is organised and quick, designed to keep turnaround times short and departures punctual.

Boarding as a Foot Passenger on the Seatran Ferry
Head into the terminal building where you can:
- Buy tickets (if not pre‑purchased) at counters or kiosks
- Ask for assistance from service staff
- Browse shops for gifts and souvenirs
- Enjoy the restaurant area with Thai dishes, hot/cold options, semi‑Western bites (including fried chicken), and ice creams
There’s a comfortable seating area if you arrive early.

Seatran Ferry Onboard Experience and Amenities
Most Seatran ferries share a similar layout:
- Vehicle deck (lowest level)
- Main passenger deck (air‑conditioned with ample seating)

Onboard you’ll find:
- A large kiosk with snacks, drinks, coffee, tea, and small souvenirs
