Xi Ding at the elevation of 1,250m is around 54k of Alishan Highway and is the nearest spot (54-56K) on Alishan Highway to watch fog. It is also an ideal place to watch the sunrise, thus earning the name of “Xi Ding” (top of sunshine). Because the highway ascends along the mountain on the way from Long Mei to Xi Ding and the airflow of Ba Zhang Stream and upper Zeng Wen Stream meet here, the unique cloudfall scenery is formed. Tourists can experience the dynamic cloudfall from Er Yang Ping Shan Pathway. Moreover, whenever the first snow falls on Mt. Jade, the beautiful snowy mountain can be seen at one glance from Xi Ding and Long Tou.

Alishan National Scenic Area establishes Er Yang Ping Shan Pathway, Cha Wu Zhi Dao and Xi Ding Zhi Xing Pathway, making Xi Ding an important resting spot on Alishan Highway for travelers.
