Doupmen Trail is a new mountain path for climbing Mount Taowu. In the past, due to military control, this trail has preserved its original natural scenery. The landscape along the trail is open and the ecosystem is rich. The entrance of the ancient trail is at the foot of Mount Taowu near Doupmen, and the destination is the place where Zheng Chenggong once inspected troops and played chess. Although the total length is only about 1 kilometer, it is not easy to walk because it is steep all the way. There is a section of the path carved into the steep granite rocks, which is quite adventurous.
