The trail follows the path of an early 20th-century water pipeline built by the Japanese to transport spring water from Yangmingshan to the Tianmu area.
The distinctive stone steps were laid during the Japanese colonial period to maintain the pipeline infrastructure.
Formosan macaque sightings are frequent, and visitors are warned not to feed them to prevent aggressive behavior.
The trail provides a transition from low-altitude urban foothills to the cloud forest environment of Yangmingshan.
Parts of the old water pipe are still integrated into the trail structure, marking the original engineering route.
The Tianmu Historic Trail, also known as the Shuiguang Historic Trail, serves as a major hiking connection between the Tianmu residential district and the Yangmingshan National Park area. The trail follows an old Japanese-era water pipeline, which remains visible along significant sections of the path. Its most distinctive feature is a grueling stretch of approximately 1,200 steep stone steps that ascend from the lower trailhead. The route traverses through a lush secondary forest canopy that maintains cooler temperatures than the surrounding city. Along the trail, visitors may encounter Formosan macaques and various species of endemic birds. The path links to the Yangming Spring trail network at its upper elevation. It serves as a primary access point for both fitness-focused hikers and those seeking a quick escape into mountain vegetation from Taipei's urban center.
