Tianyun Mountain Scenic Area is located in Xinchengzi Township, Miyun County. The main peak is 1149 meters above sea level. Standing at the top of Tianyun Mountain, we can see the snow cover in June in Wuling Mountain (see Wuling Mountain Nature Reserve), overlooking the North China Plain in the south, standing in the clouds of enemy buildings of Simatai Great Wall in the west, and looking at the Wanli Peaks outside the fortress in the north. The ancient Great Wall winds over the mountains on both sides of the East and west. The Great Wall stretches eastward from the west to form a urn city. In the city, birch forests, "Shenlu Stone", "Mandarin Duck Stone", "Stone Monkey Welcome" and other foreign stones and "Baishifeng", "Mituo Peak", "Wo Xie Peak", "Zhongyun Tower", "Lock Wu Tower", "Point Jianglou" constitute a natural park.
