The Kuang Si Falls, sometimes spelled Kuang Xi, is a waterfall about 29 kilometers (18 miles) south of Luang Prabang in Laos. These waterfalls are a favorite side trip for tourists in Luang Prabang. The falls begin in shallow pools atop a steep hillside. These lead to the main fall with a 50m cascade. The water collects in numerous turquoise blue pools as it flows downstream. The many cascades that result are typical of travertine waterfalls.
