The Yulong River (Chinese: 遇龙河; pinyin: Yùlóng Hé) is a small tributary of the larger Li River in Southeastern Guangxi Zhuang Autonomous Region that runs through the major city of Guilin to Yangshuo. The Yulong starts in Northern Yangshuo County near Litang and runs for over 35 kilometres (22 mi) through small villages of the Yulong River Valley, including Litang, Chaolong, Yima and Gaotian town, before emptying into the Li around the town of Ping Le. The Yulong is a shallow river of around 5 meters (16 ft) maximum depth and an average of 25 meters (82 ft) across. As it is not located near any industrial areas, it is clean enough for swimming, though some brownish surface foam is visible in eddys, probably the result of phosphate runoff from local villages.
