The Sai Thong waterfall is 80 metres (260 ft) wide and 5 metres (16 ft) high, and is at peak flow during the rainy season. A large pool upstream feeds the falls and provides a swimming area. At the front of the waterfall is a large basin for swimmers called Wang Sai. Also, above the waterfall is a deep body of water called Wang Ngueak whose water runs along the crooked and steep stone plateau towards Namtok Sai Thong for a distance of 150 metres.
