Guadun

　　    Guadun is a world-famous site for type specimens of biological species. Here alone, there are over 50 types of vertebrate specimens, and several species are even named after Guadun, such as the Guadun parrotbill (an endemic species of Wuyi Mountain), Guadun horned toad, and Guadun scale fern. The British Natural History Museum in London houses many biological specimens collected from Guadun, China.

　　    Guadun not only boasts a rich diversity of biological species but also features enchanting scenery. The Guadun Waterfall is 40 meters high and 6 meters wide, cascading down steep cliffs. It hangs like a curtain, breaks like mist, floats like snow, and plunges directly into a deep pool with a deafening roar, while the flying spray wets your clothes. The entire Guadun area stretches 3.5 kilometers, with winding, steep, and serene ancient paths lined with towering ancient trees and lush foliage that form a natural canopy. In the past, Guadun had three residential areas, divided into Upper Guadun, Middle Guadun, and Lower Guadun based on their elevation. At Middle Guadun, there are also the ruins of an old church built by a French priest in 1872. The French priest not only preached here but also conducted biological scientific research. Later, the church was relocated to Sangang Village’s Sankou.

　　    Here, colorful butterflies flutter, birds chirp melodiously, and insects buzz softly. Along the stream, many rare and endangered plants grow naturally, such as the fragrant fruit tree, Huangshan magnolia, tulip tree (shaped like a mandarin jacket, commonly known as "mandarin jacket tree"), and silverleaf tree. The area retains a complete set of three-level erosion surfaces, making it a sacred mountain and blessed land cherished by biologists and admired by visitors.
