By Car

The best way to get to Koh Chang requires a 4 to 4 1/2 hours trip to Trat province. Once you are in Trat, ferry services are available at three main piers to go to the island.
Route 1 : Bangna-Chonburi-Ban Bung-Klaeng-Chantaburi-Trat. Distance: 315 km.
Route 2 : (Motorway Route): Rama IX or Srinakarin-Ban Bung-Klaeng-Chantaburi-Trat.

The motorway is another alternative. Start from Rama IX Road or Srinakarin Road, then exit after paying the second toll that leads to Ban Bung, Klaeng, Chantaburi and finally Trat. The total toll fee is 60 Baht.

Route 3 : Bangna-Chonburi- Rayong-Chantaburi-Trat; Distance-385 km.

This is the other route using Highway No.3 but it takes longer as you need to pass through Chonburi and Rayong provinces.
