Koh Chang to Pattaya: bus options (2026)

2 ways to make this trip, from ฿700 one way, and 5h–6h30 on the quickest, direct. Below: what each costs, who runs it, how often it goes and the pier or station it actually leaves from.

Our pick for time

5h–6h30 · ฿700–฿1,050 · Boonsiri High Speed Ferries, Local minivan operators

Our pick for budget

Bus + ferry (one ticket)

฿700–฿1,050 · 5h–6h30 · Boonsiri High Speed Ferries, Local minivan operators

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) · 5h–6h30 · ฿700–฿1,050

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.

Bus + ferry (one ticket) + Bus · 9h25–13h30 · ฿1,025–฿1,450

Koh Chang → Bangkok: 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.

Bangkok → Pattaya: 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.

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.

Pattaya

The closest beach to Bangkok by road, and the jumping-off point for Koh Larn.

Airport UTP: 45 minutes south of the city; used more by charter and low-cost traffic than by connecting domestic passengers.

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