How to visit the River Kwai Bridge from Bangkok and which option to pick

The River Kwai Bridge is at Kanchanaburi, in western Thailand. The SRT timetable calls the station Khwae Yai Bridge (Thai: สะพานแควใหญ่), and it sits 3 km by rail beyond Kanchanaburi station on the Thonburi to Nam Tok line (119 and 116 km from Thonburi in the timetable). The line belonged to the 415 km Thailand-Burma Railway, which the Imperial Japanese Army built during the Second World War using Allied prisoners of war and forced Asian labourers. The Thailand-Burma Railway Centre (TBRC) says more than 13,000 prisoners of war died, along with around 100,000 Asian labourers. By 1957 the Thai government had reopened the section from Nong Pladuk to Nam Tok, and it still runs.

Which option to pick

Distances from DNP and the Hellfire Pass Interpretive Centre: 129 km from Bangkok to Kanchanaburi, then about 70 km to Erawan and about 80 km to Hellfire Pass. Joining the bridge, Hellfire Pass and Erawan in one day by public transport is unrealistic: that is our estimate from the distances and opening hours, as Hellfire Pass closes at 16:00. If you book a tour from a street stall, read our scams guide first.

The train from Bangkok

Thonburi station, also called Bangkok Noi, stands on the west bank of the Chao Phraya in Bangkok Noi district (OpenStreetMap). For these trains the 2026 SRT timetable lists fans and a toilet and no air-conditioning. The times below come from the SRT website on 24 October 2026.

Fares in the timetable: THB 25 to Kanchanaburi and Khwae Yai Bridge, THB 39 to Nam Tok. We did not confirm the price at the ticket office for foreign passengers. The only same-day return to Bangkok is train 258: after train 259 arrives, the timetable has no later return the same day.

On weekends and public holidays the timetable also lists a tourist train. Train 909 leaves Hua Lamphong at 06:30, reaches Kanchanaburi at 09:35 and Nam Tok at 11:30. Train 910 leaves Nam Tok at 14:25 and Kanchanaburi at 16:54 and reaches Hua Lamphong at 19:30. DNP describes it as a special tourist train for a one-day round trip. The timetable gives no fare, and SRT cancelled 909/910 on 3 and 4 October 2026 because of floods.

The closed section

According to Post Today (29 September 2026) and AEC10 News (3 October 2026), both citing SRT, the Tha Kilen to Nam Tok section was closed from 28 September 2026 because of floodwater at the Tham Krasae bridge, and train 257 ran only as far as Tha Kilen while the return trains 258 and 260 started from Tha Kilen. Tha Kilen to Wang Pho reopened on 3 October. We found no news of a full reopening to Nam Tok, and the SRT website timetable still shows the old trains. Kanchanaburi and Khwae Yai Bridge stations lie before Tha Kilen, so a day trip to the bridge is not affected by that section. Before you leave, check your train on TTS-TrainView or call SRT on 1690 (24 hours).

The bus

DNP says regular and air-conditioned buses run from the Southern Bus Terminal to Kanchanaburi every 15 minutes from 04:00 to 20:30, about 2.5 hours. Buses from Mo Chit 2 (floor 1, platform 21) towards Dan Chedi Sam Ong run from 05:00 to 19:00 and also stop at Kanchanaburi bus terminal. From there bus 8170 goes to Erawan every hour from 08:00 to 17:20. The Transport Co booking system lists a Bangkok Southern pick-up and a Kanchanaburi stop, but we did not get a fare from it, so check the price when you book. For ticketing in general see our trains and buses guide.

What to see and how long it takes

• The bridge and Khwae Yai Bridge station. Train 257 stops here at 10:34. Check on a map how to walk from the station to the bridge and back before train 258 leaves at 14:35, which leaves 4 hours
• TBRC museum and the war cemetery. The museum tells the story of the Thailand-Burma Railway and is fully air-conditioned. Its page says it opens daily 09:00-16:00 subject to official Thai closures, with admission THB 160 for adults and THB 80 for children aged 7-12. The page was last modified on 5 December 2022, so check the price. The museum stands by the war cemetery, about 1.5 km west of the town centre, and visitors reach it from the bus station by songtaew, motorbike taxi or samlor
• Hellfire Pass. A free centre run by the Australian Government, open daily 09:00-16:00 and closed on 1 January, 13-15 April, three weeks in May, 5 December, 24-27 December and 31 December. The short trail to the cutting is about 500 m and takes 45-60 minutes; the long trail is 2.6 km, 1.5 hours one way, and you must carry a safety radio that the centre lends free. It is about 80 km from the town, roughly an hour by car or 1.5-2 hours by bus for around THB 60, according to the centre. The nearest train station, Nam Tok, is 20 km away
• Erawan. A national park with the Erawan waterfall cascade. The adult foreign fee is THB 300 in the DNP table (a 2024 file, so check at the gate). The park’s welfare shop is open daily 08:00-16:30, and we found no entry hours. It is about 70 km from the town

When to go

TMD normals for 1991-2020, Kanchanaburi station (p. 49):

Climate normals do not predict the weather on one date: in the 2026 rainy season floodwater was enough to close part of the line. DNP says Erawan lies in a rain shadow and can be visited all year. For the wider picture see when to go in Thailand.

What we could not confirm

• The ticket-office fare for foreign passengers on the ordinary train, and the fare of tourist train 909/910
• The bus fare from Bangkok to Kanchanaburi
• Prices, inclusions and timing of group tours and cars with a driver
• Opening hours and conditions for walking on the bridge itself
• Opening hours of Kanchanaburi War Cemetery (the CWGC site blocks automated reading)
• The date of a full reopening of the Tha Kilen to Nam Tok section
