The trail was originally constructed to maintain a giant pipeline supplying water from the Yangmingshan mountains to the Tianmu area.
Local Formosan macaques are frequently spotted along the path and are known to habituate near human visitors.
The path includes a specific section known as the 'Love Lane' due to its popularity among local couples.
Portions of the trail pass through a subtropical rainforest zone, resulting in significantly cooler temperatures than the Taipei basin floor.
The stone stairs are uneven and date back to earlier logistical trail-building efforts in the region.
The Tianmu Historic Trail, also known as the Yulu Historic Trail, is a former water pipe path that provided the primary connection between Tianmu and Shilin for early residents. The trail is characterized by a steep initial ascent comprised of approximately 1,300 stone steps. It features a historic black cast-iron water pipe that runs parallel to the path, remnants of the area's early twentieth-century water supply infrastructure. The route traverses lush forest environments and serves as a natural habitat for Formosan macaque populations. The trail segments eventually connect to the Yangmingshan National Park network, allowing for extended hiking beyond the base trail. It functions as a popular urban-to-mountain transition point in Northern Taipei.
