Surat Thani to Koh Tao is easy with the right connection. Compare airport, train station and town transfers, ferry routes, journey times, schedules and prices to plan a smooth island getaway.
Travelling from Surat Thani to Koh Tao requires a combination of land transport and a high-speed ferry. There is no direct road connection to the island, so most travellers use a combined bus or minivan and catamaran service.
The simplest option in 2026 is a joint transfer ticket from Surat Thani Airport, Surat Thani Railway Station or Surat Thani town directly to Koh Tao. Boonsiri introduced a new van-and-catamaran service in February 2026, while Lomprayah continues to operate high-speed ferry services from the Surat Thani area.
For most visitors, booking a combined ticket is preferable to arranging every leg separately. It reduces the risk of missing the ferry connection and makes the journey considerably easier, particularly for first-time visitors to southern Thailand.
Surat Thani to Koh Tao at a glance
| Departure point | Recommended route | Approx. journey time | Typical price |
|---|---|---|---|
| Surat Thani Airport | Van/bus + high-speed catamaran | About 5 hours | From THB 950–1,100 |
| Surat Thani Railway Station | Van/bus + high-speed catamaran | About 5½–6 hours | From THB 750–1,000 |
| Surat Thani town | Hotel transfer + catamaran | About 5½–6 hours | From THB 750–1,000 |
| Donsak Pier | High-speed catamaran | About 3 hours | From THB 450–750 |
| Separate transport | Bus/minivan + ferry booked independently | Variable | Depends on each leg |
Prices and journey times vary according to the travel date, operator, departure point and seasonal timetable. The figures above are useful planning ranges rather than guaranteed fares. Boonsiri’s published 2026 timetable lists airport fares to Koh Tao at THB 1,100, railway-station and city fares at THB 1,000, and a Donsak-to-Koh-Tao ferry fare of THB 750.
1. Surat Thani Airport to Koh Tao
For travellers arriving by air, the easiest solution is a combined airport transfer + high-speed catamaran ticket.
The journey generally works as follows:
Surat Thani Airport → minivan or bus → ferry pier → high-speed catamaran → Koh Tao
A major advantage in 2026 is that travellers can book a through service rather than arranging the airport transfer and ferry independently.
Boonsiri airport service
Boonsiri’s current published schedule shows a departure from Surat Thani Airport at 11:30, followed by arrival at Koh Tao’s Mae Haad Pier at approximately 16:25. The published fare is THB 1,100 per adult.
This makes the total scheduled journey approximately 4 hours 55 minutes, although the actual travel time can vary because the service involves both road and sea transportation.
The service was introduced in February 2026 and connects Surat Thani Airport with Koh Samui, Koh Phangan and Koh Tao.
Is the airport transfer suitable for every flight?
No. The important point is the 11:30 departure.
Travellers should allow enough time for:
- Disembarking from the aircraft
- Collecting luggage
- Walking through the airport
- Finding the designated transfer point
- Checking in for the combined service
If the flight arrives too close to the scheduled departure, a same-day connection can become risky.
For a late-afternoon or evening flight, staying overnight in Surat Thani may be more practical than trying to arrange a complicated same-day connection.
2. Surat Thani Railway Station to Koh Tao
The railway station is located in Phunphin, outside central Surat Thani, so travellers should not assume that “Surat Thani train station” and “Surat Thani town” are the same departure point.
A combined ticket is the easiest option:
Surat Thani Railway Station → transfer vehicle → ferry → Koh Tao
Boonsiri’s current 2026 schedule lists a departure from the railway station at approximately 10:30, with arrival at Koh Tao at around 16:25. The published fare is approximately THB 1,000 per adult.
The scheduled journey is therefore roughly 5 hours 55 minutes.
Travelling by overnight train
The overnight train from Bangkok is a popular way to reach Surat Thani before continuing to Koh Tao.
However, train delays are possible, so a tight connection should be avoided when booking separate tickets.
A combined train-station transfer is particularly useful because the land and sea portions are coordinated.
If the train arrives too late for the available ferry connection, spending a night in Surat Thani is usually the safer option.
3. Surat Thani town to Koh Tao
Travellers staying in central Surat Thani can also use a combined transfer.
The typical route is:
Surat Thani hotel → minivan/bus → ferry → Koh Tao
Boonsiri currently lists departures from Surat Thani city hotels at approximately 10:30, with Koh Tao arrival around 16:25. The published fare is approximately THB 1,000.
This is particularly convenient for travellers who have spent a night in Surat Thani before continuing to the islands.
There is little reason to travel from the airport into Surat Thani town solely to begin the journey, however. If the airport transfer is available on the required travel date, going directly from the airport is generally more efficient.
4. Donsak Pier to Koh Tao
Donsak is the main ferry area on the mainland for services connecting Surat Thani with the Gulf islands.
If you are already at Donsak Pier, you can travel by high-speed catamaran without purchasing a land-transfer package.
Boonsiri’s current published timetable shows a 13:15 departure from Donsak, arriving at Koh Tao at approximately 16:25. The published ferry-only fare is THB 750.
The service travels through the Gulf islands, so the ferry journey is longer than a simple point-to-point crossing.
Lomprayah also lists Donsak Pier as one of its Surat Thani-area locations, alongside its Tapee Pier operation.
However, Donsak is not particularly convenient if you are arriving at Surat Thani Airport or Railway Station and have no other reason to visit the pier. In that situation, a combined transfer is usually simpler.
5. Lomprayah vs Boonsiri
Both operators are worth considering when planning a Surat Thani–Koh Tao journey.
Lomprayah
Lomprayah is one of the established high-speed catamaran operators serving the Gulf islands. Its 2026 timetable covers services involving Koh Samui, Koh Phangan and Koh Tao, while its Surat Thani operations include Donsak and Tapee Pier.
Best suited to:
- Travellers who prefer established high-speed ferry services
- Visitors comparing different sailing times
- Travellers already near one of Lomprayah’s Surat Thani departure points
- Island-hopping itineraries involving Koh Samui, Koh Phangan and Koh Tao
Boonsiri
Boonsiri has become particularly relevant for Surat Thani arrivals following the launch of its direct airport, railway-station and city transfer services in 2026.
Best suited to:
- Airport arrivals
- Train passengers
- Travellers staying in Surat Thani
- Visitors who want a single van-and-catamaran journey
The most important point is not simply choosing a ferry company. It is choosing the departure time and combined route that best matches your arrival in Surat Thani.
6. Should you book a combined ticket or separate tickets?
For most travellers, a combined ticket is the better choice.
Combined ticket
Advantages:
- One reservation covers the major parts of the journey
- Easier connection between land transport and ferry
- No need to arrange a separate taxi or minivan
- Particularly convenient for airport and railway-station arrivals
Disadvantages:
- Less flexibility if your flight or train changes
- Usually tied to a specific departure
- Fewer opportunities to change individual parts of the journey
Separate tickets
Booking each leg independently can make sense if you are already staying near the ferry pier or want to build a flexible itinerary.
However, it creates additional risks. If the bus arrives late and you miss the ferry, the ferry operator may not be responsible for the missed connection when the tickets were purchased separately.
For first-time visitors, the convenience of a through ticket generally outweighs the additional flexibility of separate bookings.
7. What is the fastest way to reach Koh Tao?
The fastest practical option depends on where you start.
If you are already at Donsak Pier, the ferry-only journey is the shortest, taking roughly three hours on the current Boonsiri service.
For travellers arriving at Surat Thani Airport, however, there is no advantage in travelling independently to Donsak unless the timing works substantially better.
A direct airport-to-Koh-Tao combination avoids an unnecessary transfer and can provide a similar overall journey time.
8. What is the cheapest option?
Among the currently published combined services, fares vary according to the departure point.
Boonsiri’s 2026 published prices are approximately:
- Surat Thani Railway Station → Koh Tao: THB 1,000
- Surat Thani town → Koh Tao: THB 1,000
- Surat Thani Airport → Koh Tao: THB 1,100
- Donsak Pier → Koh Tao: THB 750
The lower Donsak fare does not necessarily make it the cheapest complete journey. Travellers starting at the airport or railway station would first need to pay for transportation to Donsak if they are not using an included transfer.
For this reason, compare the total door-to-door cost, rather than looking only at the ferry fare.
9. What happens when you arrive in Koh Tao?
Most services arrive at Mae Haad Pier, the main arrival point on Koh Tao.
Mae Haad is close to many of the island’s central services, restaurants, dive shops and accommodation areas.
From the pier, travellers can continue by:
- Hotel pickup
- Songthaew or local taxi
- Private transfer
- Walking, if staying nearby
It is worth checking whether your accommodation provides pier pickup before arriving, particularly if you have heavy luggage or are arriving later in the afternoon.
10. Travel tips for the Surat Thani–Koh Tao route
Check the exact departure point
“Surat Thani” can refer to several different locations, including:
- Surat Thani Airport
- Surat Thani Railway Station
- Surat Thani town
- Donsak Pier
- Tapee Pier
Always check the departure location printed on the ticket.
Allow extra time after flights and trains
Do not book a connection based on the scheduled arrival time alone.
Flights can be delayed, luggage collection can take time, and trains can arrive late. A little extra buffer is particularly important during busy holiday periods.
Keep important belongings with you
Keep passports, cash, phones, medication and other valuables in a small carry-on bag rather than placing them with larger luggage.
Prepare for the ferry
High-speed catamarans can feel uncomfortable when the sea is rough.
Travellers who are sensitive to motion should consider sitting in a more stable part of the vessel and preparing appropriate seasickness medication before departure.
Check the timetable shortly before travelling
Ferry schedules can change because of weather, operational requirements and seasonal demand.
Lomprayah publishes its 2026 timetable, while Boonsiri regularly publishes timetable updates. Check the operator’s official information close to your travel date rather than relying exclusively on an old schedule.
Recommended route by arrival point
| Your situation | Best approach |
| Arriving at Surat Thani Airport in the morning | Book a direct airport-to-Koh-Tao combined service |
| Arriving by overnight train | Use a coordinated railway-station-to-Koh-Tao service |
| Staying overnight in Surat Thani | Use the city-to-Koh-Tao combined service |
| Already at Donsak Pier | Take a direct high-speed catamaran |
| Want maximum flexibility | Consider separate land and ferry arrangements |
| Travelling with a tight flight connection | Allow substantial buffer time or travel the following day |
Is Surat Thani or Koh Samui better as the gateway to Koh Tao?
Surat Thani is often the more practical mainland gateway for travellers arriving from Bangkok or other parts of southern Thailand.
Koh Samui can also be used as an intermediate stop, but routing through Samui adds another stage unless you specifically want to visit the island.
For a straightforward journey to Koh Tao, travelling from Surat Thani Airport or Railway Station directly to Koh Tao is usually the more logical itinerary.
Final recommendation
For most travellers, the best strategy is to book a combined van/bus and high-speed catamaran service that matches your arrival time in Surat Thani.
In 2026, Boonsiri’s direct services make this particularly straightforward. The current published service leaves Surat Thani Airport at 11:30 and reaches Koh Tao at approximately 16:25 for THB 1,100. From Surat Thani Railway Station or city hotels, the published departure is around 10:30, arriving at approximately 16:25 for THB 1,000.
Lomprayah remains an important alternative, particularly for travellers comparing ferry schedules or using its Surat Thani-area piers. Its official 2026 timetable should be checked for the exact sailing available on your travel date.
The key is to compare the complete journey from your arrival point to Mae Haad Pier, rather than comparing ferry prices alone.
Frequently Asked Questions
1. How long does it take to travel from Surat Thani to Koh Tao?

2. How much does it cost from Surat Thani to Koh Tao?
Current published 2026 fares are approximately THB 1,100 from Surat Thani Airport, THB 1,000 from Surat Thani Railway Station or city hotels, and THB 750 from Donsak Pier on Boonsiri’s services.
3. Is there a direct ferry from Surat Thani to Koh Tao?
There is no conventional ferry directly from central Surat Thani to Koh Tao. Travellers normally use a road transfer to a ferry departure point followed by a high-speed catamaran. Some operators sell the entire journey as one combined ticket.
4. Can I travel from Surat Thani Airport directly to Koh Tao?
Yes. A direct combined van-and-catamaran service is available. Boonsiri’s current published schedule shows an 11:30 departure from Surat Thani Airport and arrival at Koh Tao at approximately 16:25.
5. Is it better to travel from Surat Thani Airport or Donsak Pier?
If you are arriving at Surat Thani Airport, travelling directly on a combined airport-to-Koh-Tao service is generally more convenient. Going separately to Donsak adds another transfer and may not reduce the overall journey time.
6. Can I travel from Surat Thani Railway Station to Koh Tao?
Yes. Combined services operate from Phunphin Railway Station. The current Boonsiri timetable lists a departure around 10:30 and arrival at Koh Tao around 16:25, with a published fare of approximately THB 1,000.
7. Should I book the bus and ferry separately?
For most first-time visitors, a combined ticket is preferable because the land transfer and ferry connection are coordinated. Separate tickets can provide greater flexibility but create more risk if the first leg is delayed.
8. Which ferry company is best for Koh Tao?
There is no single best operator for every traveller. Lomprayah is an established high-speed catamaran operator with a 2026 Gulf timetable, while Boonsiri is particularly convenient for travellers starting at Surat Thani Airport, the railway station or city hotels.
9. Where do ferries arrive in Koh Tao?
Most services arrive at Mae Haad Pier, the island’s principal ferry terminal. From there, travellers can continue to their accommodation by local taxi, private transfer or hotel pickup.
10. Should I book in advance for Koh Tao?
Advance booking is advisable during weekends, public holidays and busy travel periods. It is also useful when arriving by flight or train because the number of suitable combined connections can be limited. Always check the latest timetable before finalising your journey.
