Literally, Guniujiang means in Chinese an ox descending from the sky. It is so named because a big rock on the peak resembles a big ox that has just landed from the sky. Straddling Qimen and Shitai Counties, the reserve covers an area of 30 square kilometers, with the Guniujiang Peak, which is the highest peak, rising 1727.6 meters high. It is one of the nature reserves of forest and wild life in China as well as an ideal place for making expedition trips. The reserve is of complex geological structure, with numerous cliffs, peaks, rocks of grotesque shapes, waterfalls, brooks and lakes. Sometimes, Buddhist halo with rainbow colors appears around the peaks, adding to the fascination of the mountain view. The natural vegetation is well preserved here, with distinct vertical distribution of plants. At the mountain top is growth of grass. Half way up the mountain are deciduous leaf trees and evergreen broadleaf trees.
