The waterfall is located within the area of the sai yok National Park at Km.46 on 323Rd. It is one of the most spectacular waterfalls in Kanchanaburi with natural green surrounding. A steam locomotive from WWII is displayed within the area as a construction memorial of the Death Railway through the waterfall via Burma.
The local people use the waterfall for having a picnic and a rest.
The highlight is that the Sai Yok Noi waterfall is once where that Death Railway was passing. So you can travel to the waterfall by the train from the bridge over the River Kwai.
