Start at the metal gates leading down to the footbridge across Yongding River, just west of Anjia Zhuang 安家庄 on the G109 road. End at the engraved stone at the entrance to Baihua Shan Scenic Area 百花山自然风景区. Don't forget to reach the highest point at c. 2020m (百花山主峰), which marks the end of the ridge line, before turning back about 2km and heading down the main path to the entrance of the Scenic Area.
