Sukhothai's ruined temples and Koh Chang's rainforest beaches sit at opposite ends of the country, and no public service links them directly. You either fly via Bangkok and Trat, or you book a private car for the whole day.
Sukhothai to Koh Chang by Flight and Ferry
Bangkok Airways flies non-stop from Sukhothai Airport (THS) to Bangkok Suvarnabhumi (BKK) in about 1 hour 10 minutes.[1] From Suvarnabhumi it flies non-stop to Trat Airport (TDX), the closest airport to Koh Chang, in about 1 hour.[2] Leave a generous connection in Bangkok, because the two flights are separate legs.
From Trat Airport a taxi or minivan takes you to Ao Thammachat pier. The ferry to Ao Sapparot on Koh Chang crosses in about 30 minutes and runs roughly every hour from 06:30 to 18:30. You buy your ticket at the pier in cash, and in 2025 a foot passenger paid about 80 baht.[3] Aim to reach the pier well before the last boat.
Sukhothai to Koh Chang by Bus via Bangkok
If you are already in Bangkok, buses to Trat leave from Mo Chit 2 at 07:30 and 08:30 for 334 baht.[4] Another service leaves Ekkamai at 07:45 and arrives in Laem Ngop at 14:30 for 292 baht.[5] From Trat, continue to the Ao Thammachat ferry as above.
Sukhothai to Koh Chang by Private Transfer
A private car takes you from Sukhothai straight to Koh Chang in about 12 hours, so start at dawn. On booking platforms, a Comfort Car for up to 3 passengers or a Luxury VIP Van for up to 9 costs about 13,550 to 15,300 baht (November 2026).[6] Shared among a group, it is the simplest way to avoid every connection.
