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.

(b) Exit from the main road, head to the left and follow the Chonburi bypass that reads Pattaya-Rayong.
(c) Head for Rayong until you see the Ban Bung-Kleng- Chantaburi and the Bang Saen- Pattaya signboards.
(d) Take the Ban Bung-Klaeng- Chantaburi route on your left. You are now on Highway No. 344.

(e) Take the right route at Ban Bung-Klaeng junction and head for Klaeng only until you reach the Chantaburi-Rayong junction. Turn left to Chantaburi but do not enter the town which is on your right. This is again Highway No. 3. Go forward until you reach the Sa Kaew-Trat junction.

(f) Take the right turn to the town of Trat.

(g) Alternatively, you can head directly to the 3 piers without passing through Trat town.  Look for the Laem Ngob signboard at
the Laem Ngob-Trat junction. Notice there is a PTT petrol station on your left just after a police checkpoint followed by another PTT station exactly 1 km away. This is the Laem Ngob-Trat junction. Turn right to Laem Ngob. This is Highway No. 3156 (Laem Ngob-Sahn Tung Road). You will reach Ao Thammachat followed by the Centre Point and Kromluang Chumphon Piers.

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.
