Koh Chang is one of the better island trips from Bangkok, but it is not close. Roughly 300 km from central Bangkok to the ferry piers at Ao Thammachat or Centre Point, and figure 5 to 6 hours of driving before you even board the boat. Add traffic leaving the city and it can stretch to seven. Here is how the trip actually works, and what it costs.
The route, plainly
You leave Bangkok on the motorway towards Chonburi, pass Pattaya, continue through Rayong and Chanthaburi, and turn off at Trat. From Trat it is about 20 to 30 minutes to the ferry pier. Ferries run roughly every 45 to 60 minutes from around 06:30 until 19:00. A car plus driver on the ferry is about ฿300 to ฿350; a walk-on passenger ticket is ฿80 to ฿100. The crossing itself is short, 25 to 30 minutes.
The last stretch matters: between the pier and your hotel on the island, roads are steep and hilly. If you rent a car on the island, take the ferry with it. If not, a songthaew from the pier to White Sand Beach or Lonely Beach runs ฿60 to ฿150 depending on distance and your negotiating.
Your options, with real numbers
Government bus. From Ekkamai or Mo Chit to Trat, roughly ฿280 to ฿320, about 5.5 hours. Then a songthaew to the pier, then the ferry. Cheapest, but that is three legs with your luggage, and buses do not connect to ferry times neatly.
Minivan. Around ฿400 to ฿600 per seat from Khao San or Victory Monument. Faster door to pier sometimes, but legroom is a rumour and drivers push the speed limit. Fine if you travel light and alone.
Private transfer. A fixed-price car from Bangkok to the pier runs about ฿3,500 to ฿4,500 for a sedan, more for an SUV or van. The advantage is the door part: hotel lobby to ferry terminal, no transfers, luggage stays in the boot.
That is the model Bangkok Ride uses: fixed price quoted up front, an airport SUV at ฿1,000 all-in for standard runs, city rides at ฿20/km, and no meter anxiety. For the Koh Chang run it means one driver, one vehicle, straight to the pier, and the price you agreed is the price you pay. If you travel with a dog or cat, there are pet-friendly vehicles you can book at /book-pet instead of arguing with a bus conductor.
Timing it right
Leave Bangkok by 07:00 and you can make an early afternoon ferry with room to spare. Leave after 15:00 on a Friday and plan your patience accordingly. The last ferries leave the mainland around 19:00, so do not cut it fine. If your flight lands at Suvarnabhumi in the evening, stay a night in Bangkok or near the pier in Trat rather than racing the schedule.
Quick FAQ
How far in advance should I book a private transfer?
One or two days ahead is usually enough, but book earlier in high season (November to March) and around Thai holidays.
Can the driver drop me directly at the ferry pier?
Yes. Vehicles drop at Ao Thammachat or Centre Point pier. The car does not board unless you have arranged to take it across.
Do I need to buy ferry tickets in advance?
No. Walk-on tickets are sold at the pier, roughly ฿80 to ฿100. Only vehicle tickets matter for planning, and only if you are bringing a car.
