The Sai Yok Noi (Small waterfall) is a popular trip destination for locals. It is mainly used for bathing and picnicking. As a result the place is crowded on weekends, tourists should visit it on weekdays.
The waterfall is actually a series of small cascades which were created by the deposition of limestone. The limestone rich water of a karst spring deposits the limestone forming rimstone dams. The white dams are filled with turquoise water, the colour is a result of the high amount of limestone. The last cascade is also the highest step, some 10 m high, and goes directly into Kwai Noi river.
The waterfall is located near Nam Tok Sai Yok Noi, a small town which is a stop on the so-called Death Railway linking Thailand with Burma. This railroad was built during World War II and was later closed. In 2004 a 1.4 km part of the abandoned railroad from Nam Tok station to Nam Tok Sai Yok Noi was reopened for the tourists. There are only two trains on this route, on Saturday and Sunday, for the tourists visiting the waterfall.
