How to get from Bangkok to Koh Chang

Koh Chang (Ko Chang) lies in the east of Thailand, in Trat province, about 300 km by road from Suvarnabhumi Airport. There is no bridge to the island, so after the mainland you need a ferry. There are three ways: fly to Trat, take a bus or minibus to the pier and then the ferry, or buy one ticket that includes a transfer to your hotel. Below are timetables and fares from the carriers, the airport and the AirAsia MOVE flight listing, checked on 13 November 2026. This is Koh Chang in Trat, not the island of the same name near Ranong.

All options in one table

Bus times and fares come from the carriers’ sites and ticketing systems where they exist, and the rest from the Bangkok Airways blog of 6 May 2026, which names a source for each figure. The 90-baht ferry is paid separately and in cash unless your ticket includes the crossing.

By plane from Suvarnabhumi to Trat

Bangkok Airways flies from Suvarnabhumi to Trat Airport (TDX) in about an hour. In the AirAsia MOVE listing on 13 November 2026 the departures are 08:10, 12:45 and 16:15, not all of them on every date; the Thai Airways flight on 19 November leaves at the same time, 12:45. One-way fares:

• 19 November at 16:15: 2,296-2,328 baht, the lowest in the listing
• 16 December: 3,693 baht
• 28 November: 3,748 baht
• 7 December: 4,665 baht
• 14 November: 5,232-5,258 baht

The listing calendar runs from 14 November 2026 to 21 February 2027, but fares are not shown for every date. The page headline promises “from 1,706 baht” and no flight card shows that fare, so we use 2,296 baht. We could not check fares on the Bangkok Airways site, which blocks automated access (13 November 2026). According to the airline’s blog the ticket includes 20 kg of baggage, meals and drinks.

Trat Airport is 17.4 km from Ao Thammachat Pier, about 23 minutes by road (OSRM). The Bangkok Airways blog says arriving passengers take local songthaews (shared pickup taxis) to the piers; it gives no fare. The 16:15 flight lands at 17:15, which leaves little margin before the last ferry at 18:30.

By bus and minibus to Trat or to the pier

Buses go either to Trat bus station or straight to Ao Thammachat Pier. Check where your ticket ends before you buy.

• Transport Co. (999). From Ekkamai to Ao Thammachat Pier there is one departure, at 07:45: 326 baht on BusOnlineTicket (which sells Transport Co. tickets) and 329 baht per the Bangkok Airways blog. The ride takes 4 h 32 min on the booking site’s timetable and about 5 h 30 min per the blog, 319 km. From Mo Chit 2 the 999 bus leaves at 07:30 for Trat bus station at 324 baht per the blog
• Cherdchai Tour. From Mo Chit 2 at 09:30 and 19:45, from Ekkamai at 11:30, 15:30, 17:30, 19:30 and 23:30 to Trat (timetable on the operator’s site). Its home page shows the Bangkok-Trat route “from 288 baht” and BusOnlineTicket lists 292 baht. The ride takes about 6 hours per the Bangkok Airways blog
• Kohchangbkk Transport. Minibuses from Ekkamai every hour from 12:30 to 18:30 and from Mo Chit 2 from 12:00 to 18:30 to Trat bus station: about 290 baht and 5 h 30 min per the blog, 300 baht on BusOnlineTicket. In the morning, from 06:00 to 11:30 from Ekkamai, there is a version with a songthaew to Ao Thammachat Pier for 370 baht

From Trat bus station you need a taxi or songthaew to the pier, whereas the 999 ticket to the pier saves you that change. Tickets are sold on the carriers’ sites, on BusOnlineTicket and at the terminal ticket offices.

One ticket with the ferry and the ride on the island

• Suvarnabhumi Burapha (SWB). Minibuses leave Suvarnabhumi at 07:00 and 11:00 and Khao San Road at 05:30 (timetable on the company’s site), and return from Koh Chang at 10:00 and 13:00. The Bangkok Airways blog gives 7 h 30 min and 800 baht with the ferry, to the SWB office on the island; the company’s site shows no fare. A van pick-up is possible if you tell them a day ahead
• Boonsiri. In its booking form for 14 November 2026 the bus leaves Khao San at 05:00, 07:00 and 08:30 and arrives at 11:35, 14:35 and 15:35, 900 baht for an adult or a child, with a transfer to your hotel on the beaches from White Sand to Bang Bao. See the booking form for child fares; prices on other dates may differ

The ferry: Ao Thammachat and the closed Centrepoint pier

Ferries run from Ao Thammachat Pier (Tha Thammachat Car Ferry Pier, Laem Ngop district, Trat province) to Ao Sapparot Pier on the north-west of the island. According to the Bangkok Airways blog of 6 May 2026:

• Hours: 06:30 to 18:30, every 30-60 minutes
• Crossing: 30-45 minutes
• Fare: 90 baht adult, 40 baht for a child of 110-150 cm
• Payment: cash only at the pier, no advance tickets

Pattaya Mail reported on 10 April 2026 that the operator revised its fare plan after a meeting of the governor with the authorities and the ferry operators: the adult fare went from 80 to 90 baht and a car from 120 to 200 baht. The operator does not publish fares on its own site, so confirm the price at the booth. Boonsiri’s post of 14 October 2025 says the Centrepoint pier has been suspended since mid-2024, and the Bangkok Airways blog says only Ao Thammachat is in use.

From the pier to your beach

The ferry arrives at Ao Sapparot. From there songthaews and taxis run to the beaches. We found no fixed fares in primary sources, so agree a price before you get in. The Boonsiri ticket at 900 baht goes as far as your hotel, and the SWB minibus as far as its own office on the island. For the choice of beach see the Koh Chang page.

Where you leave from in Bangkok

• Ekkamai. The 999 bus at 07:45, Cherdchai Tour, Kohchangbkk minibuses
• Mo Chit 2. The 999 bus at 07:30, Cherdchai Tour at 09:30 and 19:45, Kohchangbkk minibuses
• Suvarnabhumi (BKK). The SWB minibus at 07:00 and 11:00, flights to Trat
• Khao San Road. SWB at 05:30, Boonsiri at 05:00, 07:00 and 08:30
• Hua Lamphong and Krung Thep Aphiwat. No trains: the SRT station list for 13 November 2026 has no Trat station
• Don Mueang (DMK). The DMK → TDX route page on AirAsia MOVE does not open (a 404 error on 13 November 2026), and the flights in the listing leave from Suvarnabhumi

For getting from the airports to Ekkamai, Mo Chit and Khao San see Bangkok’s airports.

If you land in Bangkok late

The last ferry is around 18:30, so with an evening arrival in Bangkok you cannot reach the island the same day. Workable options:

• The Cherdchai Tour night bus from Ekkamai at 23:30: about 6 hours on the road per the Bangkok Airways blog, so you reach Trat around 05:30 and can make the first ferries at 06:30 if you find a ride to the pier quickly
• A night in Bangkok and an early start: SWB from Khao San at 05:30, Boonsiri at 05:00, the 999 bus at 07:45
• If you do miss the last ferry, stay on the mainland and sail in the morning. We have no prices for rooms near the pier

Season and sea

The rainy season on Koh Chang runs from May to October. You can see it at the mainland TMD station Trat (TRAD, 48 501, normals 1991-2020):

The best time to go is November to February. The station stands on the mainland, so its figures are no substitute for a beach forecast, and TMD says nothing about waves or ferry cancellations. More on the page Koh Chang weather.

Common mistakes

• Buying a ticket “to Koh Chang” without checking where it ends. It may end in Trat, at the pier or at your hotel, and that decides what you still pay for a songthaew and the ferry
• Counting on a ferry after 18:30. The last sailing is around 18:30, and the 16:15 flight leaves little margin
• Heading for Centrepoint. That pier has been suspended since mid-2024, according to two sources in the list below
• Not carrying cash. The ferry takes cash only, and you cannot buy a ticket in advance
• Not comparing the plane and the bus for your date. The flight is 2,296 baht on some days and 5,258 baht on others

What next

If you are coming from Pattaya, the SWB timetable has a minibus from South Pattaya to Koh Chang at 08:00, and the way to Pattaya itself is in Bangkok to Pattaya. Among the neighbouring islands, Koh Samet is closer to the capital, while Koh Tao is a longer trip through Chumphon.
