If you’ve come this far, this is a MUST.
The Hellfire Pass Interpretive Centre is about 100km from Kanchanaburi. We hired a car for the trip there and back for 2200 Thai Baht. Yes, it was expensive, but the car was air conditioned on a very hot and humid day and the trip direct. The road is a divided four lane road for about half the journey. It takes a little over an hour. There are turning lanes and a few traffic lights in the main villages/towns along the way. Other options include the three times daily train and connecting local bus (basically all day) for a fraction of the price, or local tours that include Hellfire Pass and other attractions such as the Erawan waterfall and other nearby attractions. We based ourselves in Kanchanaburi, but very long day tours are available daily from Bangkok.
The Interpretive Centre is modern, and includes toilets, car parking, and vending machines for drinks and snacks. The main part consists of backlit screens of text in English and Thai accompanying photos and sketches made by the POWs recounting the horrors of the building of the railway. There is a 10 minute film screened on a loop that is worth watching. The real benefit is visiting the track of the railway, a few hundred steps down from the Centre. A short walk (40-45 minutes return) or a longer track (3 hours) is available. The short walk takes you to the Australian Government official War Graves Commission Memorial. A US Memorial Plaque is set to be unveiled on 23 October 2023. The audio guide for the walk, with a 200 Baht deposit, is worth listening to, with POW survivors recounting their first-hand experiences. If you’ve come this far, you should visit the Interpretive Centre.
