How to Get from Koh Tao to Surat Thani

Leaving the crystalline waters of Koh Tao often feels like waking up from a dream, but the journey back to the mainland at Surat Thani connects the slow island pace with the bustling southern transit hub of Thailand. Whether you are catching a flight at the airport or heading to the railway station for a sleeper train to Bangkok, the crossing of the Gulf of Thailand gives you a final glimpse of the horizon before you return to the rhythm of the road.

Boats from Koh Tao arrive at Donsak Pier on the Surat Thani coast, and the rest of the way to the city is by road. Your choice depends on whether you want a quick morning crossing or a slow overnight drift that saves you the cost of a night's accommodation. You can compare and book these options on GoAsia.cc.

Koh Tao to Surat Thani by Ferry

The Lomprayah catamaran leaves Koh Tao at 09:30 and reaches Donsak Pier in Surat Thani province at 12:45. A ticket costs 750 baht, about $22.^[1] From Donsak you continue by road to Surat Thani town, the railway station or the airport.

Speedboat and Van Combinations

Booking platforms also sell speedboat and van combinations that take you from the pier on to your final destination, which saves you from negotiating with taxi drivers on arrival. Across all boat options on this route, fares run from about $12 to $40 (October 2026).^[2]

Sleeper Boat and Van

The Sleeper Boat is a classic Thai island experience. It leaves in the evening and lets you lie down in a shared cabin, so one ticket covers your transport and a night of sleep. A van takes you from the pier into Surat Thani town in the early morning. The whole journey takes about 12 hours 40 minutes, which makes it the slowest but most economical way to manage your schedule.^[2]

Tips for Traveling from Koh Tao to Surat Thani

• Book in Advance: During peak diving season or around the Full Moon Party on neighboring Koh Phangan, boats out of Koh Tao can sell out days in advance. Book early to avoid being stranded.
• Check the Pier: The Lomprayah catamaran arrives at Donsak Pier, not in the city center. Plan your onward transport to Surat Thani town, the station or the airport before you travel.
• Prepare for Seasickness: The Gulf of Thailand is usually calm, but high winds and rough seas can affect speedboat schedules.^[3] If you are prone to motion sickness, take medication before boarding.
• Luggage: Speedboats have limited luggage space, so keep your valuables in waterproof bags.^[3] Try to keep your gear in one main bag and a small daypack for easy boarding.
• Arrival Time: If you are heading to the airport, choose a boat that arrives several hours before your flight, because weather can delay boats.
