Same option twice: on this pair the quickest way is also the cheapest, which is rarer than it sounds — it usually means one operator has the route to itself.

Booking notes

Bus + ferry (one ticket) · 6h40–8h · ฿895–฿1,250

One ticket covers the air-conditioned coach to Ao Thammachat pier in Trat and the crossing to Ao Sapparot on Koh Chang, arriving around 14:00. Check-in closes 45 minutes before departure and the ferry does not wait for a late bus that isn't its own.

Bus + ferry (one ticket) + Bus · 7h45–12h · ฿830–฿1,250

Koh Chang → Pattaya: Skips the Bangkok backtrack if you are already on the eastern seaboard. Departures are morning-only, so an afternoon start means an overnight in Trat.

Pattaya → Bangkok: Ekkamai's Eastern Terminal is on the BTS, which makes this the rare intercity bus you can reach without a taxi. Airport services run direct from Suvarnabhumi.

Speedboat / catamaran + Bus + ferry (one ticket) · 9h45–14h30 · ฿1,620–฿2,370

Koh Chang → Koh Kood: Sailings thin out in the June–September low season and some drop entirely; check the current timetable before planning an island-to-island hop rather than a mainland backtrack.

Koh Kood → Bangkok: Longest of the eastern-island runs and the one most sensitive to a missed connection — the Laem Sok catamarans are twice-daily, not hourly. Book the bus and boat as one ticket so a late coach is the operator's problem.

Both ends of the trip

Koh Chang

Thailand's second-largest island: jungle interior, west-coast beaches, no airport of its own.

Airport TDX: Bangkok Airways only, then a 30-minute road transfer to the ferry pier.

Koh Chang has no weather station of ours; the nearest one we track is driest Nov–Apr and wettest May–Oct.

Bangkok

The arrival point for most trips and the hub every rail and bus line runs back to.

Airport BKK / DMK: Two airports 50km apart on opposite sides of the city; a domestic connection between them needs 3 hours, not 1.

Bangkok is driest Nov–Apr and wettest May–Oct on its own monthly rain-day normals.

Frequently asked questions

How long does it take to get from Koh Chang to Bangkok?

6h40–8h on the quickest option we hold — bus + ferry (one ticket) with Boonsiri High Speed Ferries. The slowest of the 3 options here takes 9h45–14h30, so the spread between them is about 4h48. Times are for the scheduled leg and exclude the transfer at either end.

How much is Koh Chang to Bangkok?

From ฿895–฿1,250 one way by bus + ferry (one ticket), checked 7 September 2026 — and on this pair that is also the quickest way, so there is nothing to trade off. The dearest of the 3 options here runs to ฿1,620–฿2,370. That band comes from a dated route listing rather than a published tariff, so treat it as indicative.

What else runs between Koh Chang and Bangkok?

2 other options. The next one after bus + ferry (one ticket) with Boonsiri High Speed Ferries is bus + ferry (one ticket) + bus with Boonsiri High Speed Ferries at ฿830–฿1,250 and 7h45–12h, changing at Pattaya — cheaper and slower. All of them are in the table above with their operators and frequency.

Does the Koh Chang to Bangkok route run all year?

Not every leg of it. 1 of the legs behind these options carries a season note — Koh Chang to Koh Kood by speedboat / catamaran: Reduced or suspended in the June–September low season. At least one option on this page runs year-round, so the route itself does not close — but the choice narrows in the monsoon.

Where does the Koh Chang to Bangkok service leave from, and how often does it run?

One ticket covers the air-conditioned coach to Ao Thammachat pier in Trat and the crossing to Ao Sapparot on Koh Chang, arriving around 14:00. Check-in closes 45 minutes before departure and the ferry does not wait for a late bus that isn't its own. One combined departure from Khao San at about 07:00.

Going the other way, or further

The return trip is on the Bangkok to Koh Chang page — fares are the same in both directions on almost every leg here, but the timetables are not. To string this hop into a longer trip with a pace check, use the route planner, and see the island comparison for which coast is dry in the month you are travelling.

The Bangkok end of this leg starts at a station or a terminal rather than a hotel door: getting around Bangkok has the BTS, MRT and boat fares for reaching Hua Lamphong, Krung Thep Aphiwat and the two bus terminals, and airport to city covers the Suvarnabhumi and Don Mueang runs if the leg is a flight.
