There are 5 major waterfalls and numerous smaller waterfalls throughout the park. The Nuo Ri Lang Waterfall is the widest travertine topped waterfall in the world. All of Jiuzhai Valley’s scenic sites were formed as a result of the build up of snow during the Quaternary period which led to the development of Jiuzhai Valley’s glaciers. These glaciers subsequently cut and carved out the valley sides and floors creating Jiuzhai Valley as we know it today.
