Quick Answer
The best way to get from Koh Tao to Surat Thani Airport (URT) is the Lomprayah Ferry & Shuttle Van combination. Total journey time is approximately 4–5 hours, and the cost is around 1,100 THB (~$31 USD). This door-to-door service departs from Koh Tao's main pier and drops you directly at the airport departure terminal. For a faster but pricier option, choose a speed boat + shuttle (3–4 hours, ~1,500 THB). The cheapest way is a ferry + local bus combination (~700 THB, 5–7 hours).
Key takeaway: Lomprayah's combined ticket is the best balance of speed, cost, and convenience for most travelers.
🚢 Ferry & Shuttle Van – The Most Recommended Way
The ferry + shuttle van combination is the backbone of transport from Koh Tao to Surat Thani Airport. It is used by over 80% of travelers and is the only true door-to-door option that does not require self-transfer between modes. The service is operated mainly by Lomprayah and Seatran, both of which offer combined tickets that include the ferry from Koh Tao to the mainland (Donsak Pier) and a connecting shuttle van directly to Surat Thani Airport.
How It Works – Step by Step
- Check-in at Koh Tao Pier: Arrive at the main pier (Mae Haad Pier) at least 30 minutes before departure. Present your e-ticket or physical ticket.
- Ferry crossing (2 hours): The ferry departs Koh Tao and crosses the Gulf of Thailand to Donsak Pier on the mainland. Seats are comfortable, with air-conditioned indoor cabins and open-air decks.
- Shuttle van transfer (1.5–2 hours): Upon arrival at Donsak Pier, follow the signs for your shuttle company. The van will depart once full (usually within 15–20 minutes) and drive directly to Surat Thani Airport.
- Drop-off at Departures: The shuttle stops right at the airport departure hall. Total time: 4–5 hours.

Why Lomprayah Is the Top Pick
Lomprayah's catamaran is significantly faster and more stable in rough seas, reducing the risk of seasickness. Their shuttle vans are new, air-conditioned, and depart more frequently. According to Tourism Authority of Thailand, Lomprayah maintains the highest safety rating among Koh Tao ferry operators.
Booking Tips
- Book at least 1 day in advance during high season (December–March and July–August) to secure a seat.
- Use 12Go for easy online booking and instant confirmation.
- Check-in luggage is included; excess baggage (over 20 kg) costs around 50–100 THB per extra 5 kg.
⚡ Speed Boat & Shuttle – Fastest but Pricier
For travelers who prioritize speed over cost, a speed boat from Koh Tao to the mainland (usually to Thong Sala Pier on Koh Phangan or directly to Donsak) cuts the sea crossing time by nearly half. Combined with a shuttle van to Surat Thani Airport, the total journey can be as short as 3–3.5 hours.
Speed Boat Options – Key Details
| Company | Sea crossing time | Total time to airport | Price (adult) | Comfort level |
|---|---|---|---|---|
| Lomprayah Speed Boat | 1 hour 15 min | 3–3.5 hours | 1,500 THB (~$42 USD) | ⭐⭐⭐⭐ |
| Seatran Speed Boat | 1 hour 30 min | 3.5–4 hours | 1,350 THB (~$38 USD) | ⭐⭐⭐ |
| Phangan Speed Boat | 1 hour 20 min | 3.5–4 hours | 1,400 THB (~$39 USD) | ⭐⭐⭐ |
Who Should Choose the Speed Boat?
- Travelers with tight flight connections – if your flight departs within 5–6 hours, the speed boat gives you extra buffer.
- Those prone to seasickness – shorter exposure to rough seas.
- Travelers willing to pay ~40% more for 1–1.5 hours saved.
Important: Speed boats have limited luggage space (max 10–12 kg per person). Heavy suitcases may incur an additional fee or be rejected. Always confirm with the operator before booking. Source: Lomprayah speed boat policy.

🧳 Traveler Tips & Experience – What They Don't Tell You
After hundreds of journeys along this route, seasoned travelers share these inside tips to make your trip smoother.
1. Seasickness – Be Prepared
The Gulf of Thailand can be rough, especially from October to January during the monsoon season. Even on a large catamaran, waves of 2–3 meters are common. Take motion sickness medication 30 minutes before departure. The Lomprayah catamaran is more stable than Seatran's standard ferry. Source: Thai Meteorological Department.
2. Luggage – Use Takkyubin (Baggage Delivery) for Heavy Suitcases
If you have large suitcases (over 20 kg), consider using Takkyubin (baggage delivery service) from Koh Tao to Surat Thani Airport. Companies like Thai Express offer door-to-door luggage delivery for ~400–600 THB per bag. Your luggage arrives at the airport within 24–48 hours. This is a game-changer for travelers with heavy gear.
3. Booking Windows – Avoid Peak Season Surprises
- High season (Dec–Mar, Jul–Aug): Book ferry + shuttle at least 2–3 days in advance. Same-day tickets often sell out by 10:00.
- Chinese New Year & Songkran (Apr): Book 1 week ahead – prices can spike 20–30%.
- Low season (May–Jun, Sep–Oct): Walk-up tickets are usually available, but afternoon ferries may be cancelled due to weather.
4. Flight Connection – Minimum Layover Advice
If you are connecting to a flight from Surat Thani Airport, do not book a flight departing less than 5 hours after your ferry departure. Delays of 30–60 minutes are common. For peace of mind, choose a flight departing after 15:00 if you take the 07:00 ferry, or after 18:00 if you take the 12:00 ferry.
5. Food & Drinks on Board
Lomprayah ferries have a small café selling snacks, instant noodles, coffee, and cold drinks. Seatran ferries have a more limited selection. Bring your own water and snacks if you have dietary restrictions. There are no food stops on the shuttle van journey.
6. Phone Signal & Wi-Fi
Mobile signal is strong on both ferries (4G/5G available) but drops in areas far from land. The shuttle vans do not offer Wi-Fi. Download movies or maps before departure. The airport has free Wi-Fi.
7. Toilet Breaks
The ferry has clean toilets (western-style). The shuttle van makes one 10-minute rest stop at a gas station halfway to the airport. Use the toilet on the ferry before disembarking.
❓ Frequently Asked Questions – Koh Tao to Surat Thani Airport
1. Is there a direct ferry from Koh Tao to Surat Thani Airport?
No, there is no direct ferry. All routes require a combination of sea and land transport. The closest you get to "direct" is the Lomprayah or Seatran combined ticket (ferry + shuttle van), which drops you at the airport without any self-transfer. This is the most convenient option.
2. What is the cheapest way to get from Koh Tao to Surat Thani Airport?
The cheapest way is to take a ferry to Donsak Pier (~600 THB) followed by a local bus to Surat Thani Bus Terminal (~80–120 THB) and then a songthaew or local bus to the airport (~30–60 THB). Total cost is about 750 THB (~$21 USD) and takes 5–6 hours. This requires navigating local transport on your own.
3. Can I use the train to get from Koh Tao to Surat Thani Airport?
Yes, but it's a multi-stage journey. Take a ferry from Koh Tao to Chumphon (2 hours), then a train from Chumphon to Surat Thani (2–3 hours), and finally a taxi or bus to the airport (20–30 minutes). Total time is 6–8 hours and costs ~1,000–1,500 THB. It's a scenic option but not recommended if you are in a hurry.
4. How early should I book my ferry + shuttle ticket?
During high season (December–March, July–August), book at least 2–3 days in advance. During low season, 1 day ahead is sufficient. For Chinese New Year and Songkran (April), book 1 week ahead to secure your preferred departure time.
5. What is the best way to travel with a lot of luggage?
If you have heavy or bulky luggage, consider Takkyubin baggage delivery (~400–600 THB per bag) from Koh Tao to Surat Thani Airport. This allows you to travel with just a day bag. Alternatively, choose a private transfer which has no strict weight limits. Lomprayah's combined ticket allows 20 kg check-in luggage per person.
6. Can I make a same-day flight connection from Koh Tao?
Yes, but with caution. If you take the first ferry (07:00) and the Lomprayah shuttle, you arrive at Surat Thani Airport around 11:00–11:30. This allows you to catch flights departing after 13:00 comfortably. For afternoon ferries (12:00), choose flights departing after 17:00. Always allow at least 2 hours between arrival at the airport and flight departure.
7. Is there a night ferry or overnight service from Koh Tao to Surat Thani?
No, there is no night ferry. The last ferry from Koh Tao to the mainland departs at 17:00. There are no overnight ferries on this route. If you have a late-night or early-morning flight, you will need to stay overnight in Surat Thani city or at the airport area and take a morning ferry.
8. What is the best option for families with young children?
For families, the Lomprayah ferry + shuttle is the best balance of comfort, safety, and value. The large catamaran has a stable ride, clean toilets, and indoor seating with air conditioning. Children under 6 usually travel at a 50% discount. If your budget allows, a private transfer offers maximum flexibility with young children (no waiting, door-to-door service, ability to stop for breaks).
