Getting to Koh Chang by road
They do have road signs in Thailand and usually they are pretty easy to follow. Getting from Bangkok to Koh Chang by either your own vehicle or by rental car is pretty simple. Driving time from Bangkok Airport to the mainland pier is around 3 and a half to four hours. From the centre of Bangkok add on another 30-45 minutes.
Briefly, all you have to do is follow the motorway out of Bangkok until you see Highway 344. Stay on the 344, looking out for police checkpoints as they like to stop drivers for no reason on this stretch of road. Join Highway 3 again near Klaeng and then, about 23km outside Trat, turn left at the T-junction with 3156, signposted to Laem Ngop. 20 mins later you’ll be at the first of the ferry piers – ‘Koh Chang Ferry’. This is the better of the two car ferry companies, with a shorter crossing time and sailings every 45 minutes from 0800 (or earlier) – 1900 daily. To reach the cheapest ferry, Centrepoint, continue approx 5km further on the 3156.
( If you follow signs marked to the ferry pier which require you to turn off the 3156 before you pass the airport, you are going the wrong way. These signs were put up by Centrepoint ferry and take you on an 18km ‘shortcut’ to a point close to their pier, avoiding driving past the Koh Chang Ferry pier.)
This video shows the route from Bangkok Airport to Koh Chang. if you were coming out of the centre of Bangkok, follow signs for the airport and then the route shown is the same as the Googlemap.
Ticket prices for the 30 minute crossing from Ao Thammachat, on the mainland, to Ao Sapporot, on Koh Chang by Koh Chang Ferry are as of late 2012:
Passengers: 80 Baht one way ( Adults ) 30 Baht for kids
Cars: 120 Baht one way
There is another ferry – Centrepoint – which is cheaper but takes an age and if you’re travelling at very low tide it isn’t uncommon that ferries get stuck on a sandbar. I haven’t used it for years.
