Peony Peak Natural Reserve is located in the northwest end of the Laoyeling Mountains, connecting Taiping Mountain in the east and next to Zhangguangcai Mountain in the west. It is a fantastic natural spot for primitive zoology and also stands as a national nature reserve with a total area of 400 square kilometers.
Peony Peak was once a lake with clean, active waves. About 9 million years ago, the volcano body was formed after a volcanic eruption, mostly being basalt. The volcano body was later continually eroded by floodwaters, along with the descending and ascending of the earth’s crust, which also formed the features of the superposed mountains and interlaced ravines. The highest point of Peony Peak can be found 1,111 meters above sea level.
