Quick Answer
The best overall way to get from Surat Thani Airport to Koh Samui is by pre-booking a combined minivan + ferry ticket (often called a “joint ticket” or “bus-ferry combo”). The journey takes approximately 3.5 to 4.5 hours total and costs between ฿600 to ฿900 ($17-$26 USD). The key transfer point is Donsak Pier, where you switch from road transport to the ferry bound for Koh Samui. For the cheapest option, take a local bus from Surat Thani town (reached by airport shuttle) to Donsak, then a public ferry.
Option 1: Private Minivan or Shared Transfer (Most Convenient)
This is the most popular and hassle-free method for tourists. You book a single ticket that covers your journey from the airport arrival hall directly to your destination on Koh Samui, involving a minivan ride to Donsak Pier and a ferry crossing.
How It Works: Step-by-Step
- Booking: Book online in advance (highly recommended) via platforms like 12Go.Asia or directly with operators like Lomprayah or Seatran.
- At Surat Thani Airport (URT): Look for the operator's desk or a representative holding a sign with your name. They will direct you to your minivan.
- Minivan to Donsak Pier (~1.5-2 hours): A comfortable, air-conditioned van will drive you directly to the pier. Some services use larger buses.
- At Donsak Pier: The staff will often handle your ferry ticket. You may need to wait (usually not long) before boarding.
- Ferry to Koh Samui (~1.5-2 hours): Board the car ferry or high-speed catamaran (depending on operator).
- Arrival on Samui: Disembark at either Nathon Pier (main town) or Maenam Pier. From there, shared songthaews (pick-up truck taxis) or private taxis will take you to your final hotel.
Operator Comparison & What to Expect
| Operator | Vehicle Type | Ferry Type | Samui Arrival Pier | Approx. Total Duration | Price Range (THB) |
|---|---|---|---|---|---|
| Lomprayah | Luxury Bus / Minivan | High-Speed Catamaran | Maenam Pier | ~3.5 hours | 800 - 950 |
| Seatran Discovery | Minivan / Bus | Car Ferry / Speedboat | Nathon Pier | ~4 - 4.5 hours | 600 - 800 |
| Raja Ferry | Minivan | Large Car Ferry | Lipa Noi Pier | ~4.5 - 5 hours | 550 - 700 |
Pros: Door-to-door service, minimal thinking required, tickets often include pier transfers, reliable timing. Cons: Slightly more expensive than piecing it together yourself, you are on a fixed schedule, can be crowded in high season.
Option 2: Public Bus & Airport Bus (Most Economical)
For budget travelers, this is the cheapest way to reach Koh Samui. It requires more steps and local knowledge but can cost less than ฿400.
Two Main Bus Options:
A) Direct Airport Bus to Donsak Pier (Shared Minivan)
Some shared minivan services operate directly from the airport to Donsak Pier without a pre-booked joint ticket. Look for counters inside the airport arrivals hall. This is more expensive than local buses but easier. Expect to pay ฿250-฿400 for the van ride, plus you must buy the ferry ticket separately at the pier (฿150-฿250).
B) Local Public Bus (The True Budget Route)
- Airport to Surat Thani Town: Take the airport shuttle bus (฿100) or a local songthaew (฿50-80) to Surat Thani Bus Terminal (Talad Kaset 2).
- Bus to Donsak Pier: From the bus terminal, board a local bus bound for Donsak. These depart frequently, take about 1.5 hours, and cost ฿70-฿100. Confirm with the driver "Donsak Pier?"
- Ferry Ticket: At Donsak, buy your ferry ticket at the Raja Ferry or Seatran counter.
- Onward Transport on Samui: From Nathon Pier, take a public songthaew to your beach area (฿50-150 per person).
Total Cost: ~฿270 - ฿550. Total Time: 5+ hours (variable).
Pros: Extremely cheap, authentic local experience. Cons: Time-consuming, multiple changes, potential language barrier, not suitable with lots of luggage, no air-conditioning on some local buses.
Option 3: Taxi or Private Car (Most Expensive, For Flexibility)
This option is generally not recommended for most travelers due to its high cost, but it suits specific situations.
Costs & Practicalities
- Metered Taxi: Rarely available at the airport. If found, the meter to Donsak (100km+) would be exorbitant.
- Private Hire Car/Van: You can negotiate with drivers at the airport or book via Grab (app works in Surat Thani). Expect a fixed price of ฿2,500 to ฿4,000+ for the car (not per person) to Donsak Pier, depending on vehicle size and negotiation skills.
- Journey: The driver takes you directly to Donsak. You must then buy and board the ferry as a foot passenger (car ferries allow this).
When Does This Make Sense?
- Late-Night/Early-Morning Arrivals: When bus/transfer services are not operating.
- Small Groups (4+ people): The cost can be split, potentially making it competitive with private transfers.
- Travelers with Mobility Issues or Excessive Luggage: Direct, door-to-pier service.
- Urgent Travel: You leave immediately without waiting for other passengers.
Warning: Always agree on a firm, all-inclusive price before getting in the vehicle.

Traveler Experience & Essential Tips for 2024
Pro Tips for a Smooth Journey
- Book Ahead in Peak Season: December-January, Songkran (April), Chinese New Year. Joint tickets sell out days in advance.
- Manage Your Luggage: Keep it minimal. You'll be loading/unloading from van to ferry and possibly walking on piers. Consider sending large bags via Thai luggage delivery services (e.g., Samui Tour) if you have excess.
- Time Your Flight: Ideally, land before 3:00 PM to catch the last popular ferry connections (often around 5:00-6:00 PM from Donsak).
- Bring Supplies: Water, snacks, a jacket (for strong A/C on vans/ferries), and entertainment for the ~4-hour journey.
- Cash is King: Have Thai Baht for incidental purchases, tips, or local transport on Samui. Some pier shops/counters may not accept cards.
- Beware of “Too-Good-To-Be-True” Offers: Touts at the airport may offer very cheap tickets to unrelated piers or slower services. Stick to official counters or your pre-booked ticket.
What If My Flight is Delayed?
If you have a pre-booked joint ticket, contact the operator immediately via the phone number on your voucher. Reputable companies like Lomprayah often put you on the next available departure if space permits, but this is not guaranteed. This is another reason to book with a major, reliable operator.
FAQs: Getting from Surat Thani Airport to Koh Samui
Is there a direct bus from Surat Thani Airport to Koh Samui?
No. There is no single vehicle that goes directly from the airport to the island. All options require a transfer to a ferry at Donsak Pier. The “direct” services refer to through-ticketed minivan+ferry combinations.
What's the fastest way from Surat Thani Airport to Koh Samui?
The fastest way is a pre-booked joint ticket using Lomprayah's high-speed catamaran service, with a total travel time of around 3.5 hours from airport to Maenam Pier.
What's the cheapest way from the airport to Samui?
The absolute cheapest way is using local public transport: airport shuttle to Surat Thani town (~฿100), local bus to Donsak (~฿70), and public ferry (~฿150). Total can be under ฿350.
Can I book tickets on arrival at the airport?
Yes, but it's risky during high season (Dec-Feb, holidays). Departures can be full, forcing you to wait several hours. Booking online at least a few days in advance is strongly recommended.
What if my flight arrives late at night?
Most ferry services from Donsak end by 7:00 PM. If you land after ~4:00 PM, your safe options are: 1) Pre-book a private taxi to Donsak for the last ferry (check times!), 2) Stay overnight in Surat Thani town and travel the next morning (most economical and stress-free).
Is it easy to travel with children or a lot of luggage?
It's manageable but not easy. The pre-booked minivan+ferry combo is the best choice as staff often help with luggage. For large groups/families with lots of bags, consider a private van charter or splitting the cost of a private taxi.
Which pier on Koh Samui is best to arrive at?
It depends on your final destination:
- Nathon Pier (Seatran): Best for the west coast (Nathon, Lipa Noi) and central access to all beaches.
- Maenam Pier (Lomprayah): Best for the north coast (Maenam, Bophut, Choeng Mon).
- Lipa Noi Pier (Raja): Best for the southwest coast (Lipa Noi, Taling Ngam).
Are there any luggage restrictions on the buses or ferries?
Generally, no strict weight limits for foot passengers, but space is limited. One large suitcase + one carry-on per person is standard. Oversized or excessive luggage may incur an extra charge or be refused on crowded minivans.
