Did not know what to call this post, as we stayed in Chaiyaphruek Village, which is also referred to as Nam Tok, as the railway station is called. Sai Yok is the district, with nearby Erawan National Park, and further up to the Hellfire Pass memorial & museum.
It seemed like we were the only people on the train, as this station is the end of the railway line, after passing through Kanchanaburi earlier on the route.
However we found a nice quiet village with a very welcoming family at the guesthouse, we rented a scooter and went around 50km to the national park. The waterfalls at Erawan National Park were very impressive, and there are several as you walk up through the park.
Another place visited was the Hellfire Pass memorial and visitor centre. Here there is a detailed museum explaining the horrors and awful conditions that prisoners of war were subject to when building the railway, during World War II.
It was very moving to visit the memorial, and walk along the historic railway cutting shown below.
