The quickest way from Bangkok to Kanchanaburi is a minivan or bus from the Southern Bus Terminal (Sai Tai Mai), about two to two and a half hours for around 110 baht. The most atmospheric is the slow third-class train from Thonburi station, which takes about two hours 45 minutes and leaves twice a day, at 07:45 and 13:55.
Kanchanaburi lies west of Bangkok, near the Myanmar border, and is famous for the bridge over the River Kwai and the wartime Death Railway. It is close enough for a long day trip, but most visitors stay at least one night. None of the options requires booking far ahead, except the weekend excursion train.
This page covers only the trip from Bangkok to Kanchanaburi town. The rail journey further west, over the Wang Pho viaduct to Nam Tok, has its own guide: riding the Death Railway. What to do once you arrive is in our Kanchanaburi guide.
Erawan and Sai Yok national parks closed after the September 2026 storms. Erawan National Park closed on 27 September 2026, and Thai press reported damage at the waterfall tiers after a survey on 30 September. On 2 October the Thai National Parks website said Erawan would reopen on 3 October, but we found no notice from the Department of National Parks confirming it. Sai Yok National Park closed its waterfalls and caves from 27 September until further notice, and Srinagarind Dam National Park closed several sites. Check the status before you build your trip around them; our Erawan page explains how.

The train from Thonburi station
The ordinary trains to Kanchanaburi do not use Krung Thep Aphiwat or Hua Lamphong. They start at Thonburi station (formerly called Bangkok Noi) on the west bank of the Chao Phraya. Thonburi is about a nine-minute walk (750 meters) from Bang Khun Non station on the MRT Blue Line. The trains also stop one station out at Jaran Sanitwong, right next to Bang Khun Non MRT, which can be easier to reach.
According to the timetable published by seat61.com (updated October 2026), the departures are:
| Train | Thonburi | Nakhon Pathom | Kanchanaburi | River Kwai Bridge |
|---|---|---|---|---|
| 257 | 07:45 | 08:58 | 10:30 | 10:35 |
| 259 | 13:55 | 15:03 | 16:21 | 16:26 |
Back to Bangkok, trains leave Kanchanaburi at 07:05 and 14:43, reaching Thonburi at 09:35 and 17:40. Seat61 itself prints the afternoon departure as 13:45 in one passage, and another guide gives the morning train as 07:50, so arrive at Thonburi at least 15 minutes early and check the board.
The trains are third class only, with vendors walking through selling snacks and drinks. You cannot reserve a seat; you buy the ticket at the station on the day, and the train cannot sell out. Seat61 reports a fixed fare of 100 baht for foreign visitors, but the State Railway has not confirmed this on its own site, which we could not reach in October 2026.
Take the train if the journey matters to you: rice fields, small stations and a slow approach to the river. Skip it if you are short of time or traveling with heavy luggage, and expect the afternoon train to be hot.
Use the MRT to reach Thonburi station, not a tuk-tuk. Thonburi station is awkward to reach by road from Khao San Road and the old town, and drivers know it. The MRT Blue Line to Bang Khun Non, followed by a short walk or a hop to Jaran Sanitwong, is predictable and cheap. Our page on the BTS and MRT explains how the lines work.
Changing at Nakhon Pathom from the south
If you are coming from Hua Hin, Surat Thani or further south, you do not need to go into Bangkok. Express trains from the south stop at Nakhon Pathom, about 64 kilometers west of Bangkok, and the Kanchanaburi trains call there at 08:58 and 15:03. The actual junction is at Nong Pladuk, but express trains do not stop there, so change at Nakhon Pathom.
The weekend excursion train from Hua Lamphong
On Saturdays, Sundays and public holidays, the State Railway runs a special excursion train from Hua Lamphong, Bangkok's old central station. According to seat61, it leaves at 06:30, stops for 40 minutes at Nakhon Pathom to see the great chedi, reaches Kanchanaburi at about 09:26, pauses at the River Kwai bridge and continues to Nam Tok Sai Yok Noi. The return trip arrives back at Hua Lamphong at about 19:25, with a stop at the war cemetery in Kanchanaburi.
Unlike the daily trains, this one needs a reservation, often sells out, and is sold through the State Railway's D-Ticket system or at stations; our guide to booking Thai trains online explains the system. Seat61 gives the round-trip price as 120 baht in third class or 240 baht in second class, but its pages disagree on which carriages have air-conditioning.
There is a bigger problem in October 2026. The train turns at the Sai Yok Noi waterfall, inside Sai Yok National Park, whose waterfalls and caves have been closed since 27 September 2026. We could not confirm whether the excursion is running or what it does instead, so check with the State Railway (call center 1690) before you book.
Minivans and buses from the Southern Bus Terminal
Road transport leaves from the Southern Bus Terminal, known as Sai Tai Mai, in Taling Chan on the Thonburi side. It is far from Sukhumvit and Silom, so allow time for a taxi or Grab ride there.
The operator Kanchanaburi Express lists minivans from Sai Tai Mai at 07:00 and 16:00, taking about 2 hours 30 minutes and costing 110 baht, and in the other direction from Kanchanaburi Bus Terminal at 08:30 and 16:30 (October 2026). It also runs from the Chatuchak (Mo Chit) new van terminal in the north of the city at 07:00 and 16:00, about three hours, 130 baht, with returns at 08:30 and 15:20. These are the trips shown on its booking site; there may be more on the day.
Large buses also run. The Thai National Parks website lists frequent first-class buses on route 81 from the Southern Bus Terminal throughout the day, taking about two hours. The state bus company's own site was unavailable when we checked, so confirm times at the terminal.
Minivans and buses arrive at Kanchanaburi Bus Terminal in the center of town, not at the River Kwai bridge. Most guesthouses along the river are a short tuk-tuk or Grab ride away. For general advice, see our guides to minivans in Thailand and long-distance buses; a minivan has little room for large suitcases, so take the bus if you carry one.
Taxi, Grab or driving yourself
A taxi or a Grab car from your Bangkok hotel takes you straight to your Kanchanaburi guesthouse, and Grab lists Kanchanaburi among the provinces where it operates. It is the most comfortable choice for families or groups of three or four, who can split the cost. We could not verify a current fare, so compare the Grab quote with the price your hotel can arrange.
Driving a rental car is also straightforward, and it lets you continue west to Hellfire Pass and the Wang Pho viaduct at your own pace. For the full route and road advice, see our sister site's guide to the Kanchanaburi and Death Railway drive.
Which option should you choose?
| You want | Choose | Why |
|---|---|---|
| The fastest and cheapest trip | Minivan or bus from Sai Tai Mai | About 2 to 2.5 hours, around 110 baht |
| The experience of the line | Train from Thonburi | Slow, scenic, cheap; no booking |
| A one-day sightseeing trip on a weekend | Excursion train from Hua Lamphong | Includes stops, but check its status in October 2026 |
| Comfort with luggage or children | Taxi or Grab | Door to door, no transfers |
A good combination is the morning train out, to enjoy the ride, and a minivan back to Bangkok, which is quicker at the end of a long day.
Frequently asked questions
Which Bangkok station do trains to Kanchanaburi leave from?
The daily trains leave from Thonburi station on the west bank of the river, a short walk from MRT Bang Khun Non. Only the weekend excursion train uses Hua Lamphong, and no Kanchanaburi trains use Krung Thep Aphiwat.
How long does it take to get from Bangkok to Kanchanaburi?
About two to two and a half hours by bus or minivan from the Southern Bus Terminal, about three hours from Mo Chit, and about two hours 45 minutes by train from Thonburi, according to operator and seat61 timetables.
Do I need to book the train to Kanchanaburi in advance?
No, not the daily trains: they are third class only and you buy the ticket at the station on the day. The weekend excursion train from Hua Lamphong is different and needs a reservation.
Is Erawan Falls open?
Check on the day. Erawan National Park closed on 27 September 2026 after storm damage. On 2 October the Thai National Parks website announced a reopening on 3 October, but no official Department of National Parks notice confirmed this when we checked, so ask your guesthouse or the park before you go.
