Highlights: A section running about four kilometers along the river is the Four Caves Valley Scenic Area. Four waterfalls are arranged at roughly equal distances, named the Water Curtain Cave, the Moon Pool, the Flying Frog Cliff and the White Dragon Pool, each with its own unique style. There are also cultural landscapes in the scenic area such as Zheng's Stone Arch, “Calun Paper Mill” and several Danxia landforms, including the magical Shixiang Mountain and Duxian Bridge.
