Quick Answer
The best and most recommended way for most travelers is the direct shuttle bus + ferry combo ticket. Upon arrival at Surat Thani Airport (URT), buy a combined ticket from the Seatran or Raja Ferry counters in the arrivals hall. A shuttle bus will take you directly to Donsak Pier (1-1.5 hours), where you board a waiting ferry to Koh Samui (1.5 hours). Total cost starts at ~300-400 THB, and total travel time from airport to Samui is roughly 3.5 to 5 hours depending on connections.
Option 1: Shuttle Bus & Ferry Combo (The Standard & Recommended Choice)
This integrated service is specifically designed for air passengers and is the most efficient public transport link. Ferry companies operate coordinated shuttle buses that match flight arrivals with ferry departures from Donsak Pier.
Step-by-Step Process:
- Arrive & Find the Counters: After baggage claim at URT, you'll see clear signage for "Ferry to Koh Samui" leading to the Seatran and Raja Ferry ticket counters.
- Purchase Your Combo Ticket: Buy a combined ticket covering the shuttle bus ride to Donsak Pier and the subsequent ferry crossing to Koh Samui. You can choose your preferred ferry company.
- Board the Shuttle Bus: Wait in the designated area outside the terminal. Staff will guide you to the correct air-conditioned minibus or coach when it's ready.
- Journey to Donsak Pier: Enjoy the 1 to 1.5-hour ride through the countryside. Your luggage is stored below.
- Ferry Check-in & Crossing: At Donsak, you may need to switch your ticket for a boarding pass. Then board the large car ferry for the 1.5-hour scenic journey to Koh Samui.
| Operator | Approx. Cost (Bus+Ferry) | Samui Arrival Pier | Pros | Cons |
|---|---|---|---|---|
| Seatran Ferry | 300 - 450 THB | Bangrak Pier (North Samui) | Frequent departures, well-organized. | Bangrak Pier can be busy. |
| Raja Ferry Port | 300 - 450 THB | Lipa Noi Pier (Southwest Samui) | Often slightly cheaper, less crowded pier. | Pier is further from popular tourist areas. |

Who Should Book This?
Almost all travelers: Solo backpackers, couples, families, and small groups. It's cost-effective, hassle-free, and reliable. Booking online in advance is advised during holidays (Thai public holiday calendar) to secure your spot.
Option 2: Taxi or Private Transfer (Door-to-Door Convenience)
Private taxis and pre-booked cars offer a direct, exclusive ride from the airport terminal directly to Donsak Pier. This is the most flexible but also the most expensive option by a large margin.
What to Expect:
- Cost: 1,500 - 2,500 THB for the car (not per person). Price is fixed at the airport taxi desk or agreed upon beforehand with a driver.
- Vehicle: Standard sedan or SUV for up to 3-4 passengers with luggage.
- Journey Time: Approximately 1 hour, potentially faster than the shuttle bus as it makes no stops.
- Booking: Available on arrival at the official airport taxi desk, or pre-book via services like Klook or 12Go Asia.
Who Should Choose a Taxi?
Only consider this if: You are a group of 3-4 people (splitting the cost makes it reasonable), you arrive after the last shuttle bus has departed, you have an extraordinary amount of luggage, or you have mobility issues. For solo travelers or couples, the cost is not justified given the efficiency of the shuttle bus.
Warning: A taxi only gets you to Donsak Pier. You must still purchase a separate ferry ticket there. Unlike the shuttle combo, the timing is your responsibilityâensure you arrive before the last ferry of the day.
Option 3: Local Public Bus (The Budget Adventure)
This is the authentic, ultra-low-cost method involving multiple local transfers. It is not recommended for first-time visitors, those with heavy luggage, or anyone on a tight schedule, but it offers deep cultural immersion at a rock-bottom price.
The Complex Journey:
- Airport to Surat Thani City Bus Station: Take a local songthaew (shared pickup truck taxi) from outside the airport to the city's main bus station. Cost: ~50 THB. Time: 30-45 mins.
- Bus to Donsak: From Surat Thani bus station, board a local bus bound for Donsak. Cost: ~60-80 THB. Time: 1.5-2 hours.
- Walk to Pier & Buy Ferry Ticket: The bus terminates near Donsak Pier. Walk to the ferry terminal and purchase a stand-alone ferry ticket (~150-200 THB).
Total Cost: ~260-330 THB. Total Time: 4+ hours (highly variable).
Who Should Attempt This?
Only extremely budget-conscious backpackers with ample time, very light luggage (a single backpack), and a high tolerance for uncertainty and basic transport. The risk of missed connections and the lack of English signage make it challenging. The minimal savings over the direct shuttle combo (often less than 100 THB) are rarely worth the significant extra hassle and time.

Traveler Experience & Essential Tips
Beyond the schedules and prices, here are the insider tips that will make your transfer smoother.
1. Manage Your Luggage & Comfort
- Pack Light for the Ferry: You'll need to carry your bags on/off the shuttle bus and up/down the ferry ramp. Wheeled suitcases are fine, but oversized items (e.g., golf bags, large dive gear) can be problematic. Declare them when buying your ticket.
- Ferry Amenities: Both Seatran and Raja ferries have basic amenities: indoor/outdoor seating, a small snack bar, and restrooms. The crossing can be windy on deck.
2. Timing is Everything
- Flight Arrival vs. Last Bus: This is the most critical factor. If your flight lands after 5:00 PM, research the last shuttle departure time (often 6:00-7:00 PM). Have a backup plan, which usually involves staying in Surat Thani city for the night.
- Buffer Time: Allow at least 3.5 hours from your flight's scheduled arrival to a reasonable expectation of being on Koh Samui. Delays happen.
3. Onward Travel from Samui Piers
Your journey isn't over when you reach Samui. Both piers have taxi and songthaew services, but they can be expensive. Know your pier:
- Bangrak Pier (Seatran): Close to Bophut and Chaweng. A taxi to Chaweng costs ~300-400 THB.
- Lipa Noi Pier (Raja): Far from major beaches. A taxi to Chaweng can cost 600+ THB.
Consider pre-booking a Samui taxi transfer if your hotel is far from the pier.
FAQs: Your Surat Thani Airport to Pier Questions Answered
Is there a direct bus from Surat Thani Airport to Donsak Pier?
Yes. The direct shuttle bus service operated by Seatran and Raja Ferry is the primary and recommended transfer method. It is not a public city bus but a coordinated transfer for ferry passengers.
How long is the transfer from Surat Thani Airport to Donsak Pier?
The road journey takes 1 to 1.5 hours. The entire process from airport arrival to stepping onto Koh Samui, including waiting, bus ride, ferry boarding, and the 1.5-hour crossing, typically takes 3.5 to 5 hours.
What is the cheapest way to get from URT Airport to Donsak Pier?
The cheapest practical way is the shared shuttle bus + ferry combo ticket (~300-400 THB). The local bus method is slightly cheaper but so inconvenient and time-consuming that the small savings are negligible for most.
Can I book a taxi from Surat Thani Airport to Donsak Pier?
Yes, but it's costly (1500-2500 THB/car). It is not recommended for solo travelers or couples. It is only cost-effective for groups or a necessary choice for very late-night arrivals when shuttles have stopped.
What happens if my flight arrives late at night?
This is a common problem. Your realistic options are: 1) Take an expensive taxi to Donsak (if a ferry is still running), or 2) Stay overnight in Surat Thani town (hotels near the bus station are cheap) and take the first morning shuttle. Always check your flight's arrival time against the last shuttle bus schedule.
Should I buy my bus+ferry ticket online or at the airport?
For peace of mind, book online in advance, especially during peak season (Dec-Jan, July-Aug) or if arriving on a late afternoon flight. Walk-up tickets are usually available but not guaranteed.
Is the shuttle bus comfortable for long-haul travelers with luggage?
The buses are standard, air-conditioned tourist vehicles. They are comfortable for the relatively short ride. Luggage is stored below. If you have exceptionally large or fragile items, contact the operator after booking to confirm they can be accommodated.
Which is better: Seatran Ferry or Raja Ferry from Donsak?
Service quality is comparable. The key difference is the arrival pier on Koh Samui. Choose Seatran if your hotel is in the north/northeast (Bophut, Chaweng). Choose Raja if your hotel is in the southwest or west (Lipa Noi, Taling Ngam). Always cross-check the latest schedules when booking.
