The summit of Jialishan is recognized as one of the 'Small Hundred Peaks' of Taiwan.
The trail connects to the former route of the Jiali Mountain Forestry Railway, which was once utilized for timber extraction.
The trail features a distinct transition from artificial Japanese cedar plantations at the base to natural mixed-hardwood forests at higher elevations.
The route requires ascending approximately 800-900 meters in total elevation gain from the trailhead.
Due to the high elevation and density of the forest, the area experiences frequent 'cloud sea' (yunhai) phenomena.
Jialishan Trail is a renowned mid-altitude mountain hike in Miaoli County, Taiwan, reaching an elevation of 2,220 meters. The trail is noted for its high-altitude cedar forests, misty cloudscapes, and the presence of ancient cypress remnants. It features a technical section near the summit requiring the use of ropes for climbing over rocky terrain. The route follows the path of historical forestry railways used during the Japanese colonial period. Hikers frequently encounter a mix of broad-leaved and coniferous forest ecosystems as they ascend. The summit offers panoramic views of the Hsinchu and Miaoli mountain ranges on clear days.
