No town in Thailand is complete without a night market where you can gorge yourself silly on incredible local food at rock bottom prices, and Kanchanaburi is no exception. You’ll find the night market near to the main train station, with all the tasty food you can eat, as well as clothing, movies and so on.
There is a lot more to do in the Kanchanaburi area beyond that above, and you could easily spend a heap of time relaxing and exploring here. I’d recommend giving it more than a passing glance – you won’t regret it.
