Went there when I first visited Thailand with my now ex. Stayed at the bamboo House on the River Khwae (Kwai). Visited Hellfire Pass, the Cemetery, museum and waterfall. Good history. Took the slow train from Bangkok, the same train used back then on wooden tracks. You can see it in the Railway Man movie, along with him standing on the bridge, where you can walk to the other side and relive history. Visited Erewan Park also, with the 7 waterfalls.
