There are three routes leading to Huashan's North Peak (1,614 m (5,295 ft)), the lowest of the mountain's five major peaks. The most popular is the traditional route in Hua Shan Yu (Hua Shan Gorge), first developed in the 3rd to 4th century A.D. and with successive expansion, mostly during the Tang Dynasty. It winds for 6 km from Huashan village to the north peak. A new route in Huang Pu Yu (Huang Pu Gorge, named after the hermit Huang Lu Zi who lived in this gorge in 8th century BC) follows the cable car to the North Peak, and is actually the ancient trail used prior to the Tang Dynasty, which has since fallen into disrepair. It had only been known to local villagers living nearby at the gorges since 1949, when a group of seven People's Liberation Army soldiers with a local guide used this route to climb to the North Peak and captured over 100 Kuomintang soldiers stationed on the North Peak and along the path of the traditional route. This trail is now known as "The Intelligent Take-over Route of Hua Shan", and was reinforced in early 2000. The Cable Car System stations are built next to the beginning and ends of this trail. A second cable car line, to the West Peak, was opened in 2013.
