You depart by crossing the infamous Bridge over the River Kwai and into the Kwai Noi valley, stopping regularly at stations throughout the route. The first stop of note is Tha Kilen, a handy stop for the Khmer temples of Prasat Muang Singh National Park.
The most nerve-wracking section of the track comes 20 minutes after Tha Kilen, at Arrow Hill, also known as Wang Sing. The train barely fits through the 30m-deep solid rock tunnels, whose construction cost the lives of hundreds of Allied POWs in WWII and gave the railway its sinister nickname. Just 6km further up the line, the train slows on approach to the Wang Po viaduct, a 300m-long wooden bridge that clings to the cliff face with the Kwai Noi river below.
The station at the northern end of the bridge is Tham Krasae, named after the cave hollowed out of the rock face beside the bridge. Visible from the train here is the cave’s resident Buddha. The end of the line is Nam Tok, a small town that thrives mainly from tourism.
The train departs three times daily.
Our Spin For the best views of the surrounding countryside, sit or stand on the left hand side of the train when travelling from Kanchanaburi and sit or stand on the right on the journey back. The train is often delayed and running late so don't be too disappointed if you're forced to wait a bit.
