Nan'en Waterfall is located in Ailao Mountain National Forest Park, Gasa Town, Xinping Yi Autonomous County, Yuxi City, Yunnan Province. Nan'en Waterfall originates from Ailao Mountain and is called Nan'en River. The Nan'en Waterfall has a turbulent river and fierce water. Many waterfalls have formed in the mountains, of which the most famous is Nan'en Waterfall. The waterfall spans up to 100 meters, like a jade belt inlaid in the Ailao Mountain. The waterfall is surrounded by cliffs and strange rocks. When you walk into the waterfall, the water rushing down from the mountain is huge. A snow-white waterfall flows down from the top of the mountain, as if it came out of the sky, with waves flying straight down, and the waterfall falling thousands of feet from the cloud peak. The sound of the valley is like thunder in spring, which is very spectacular.
