The canal system is composed of three separate channels: the Upper, Middle, and Lower Pingding Canals, which were built sequentially to expand irrigation capacity.
Construction was initiated by the local Wang, Xu, and Rong families to resolve water shortages for the valley's rice paddies.
The water is sourced from the clean, high-altitude streams of the Neishuangxi River via a diversion weir.
The canal remains a functional irrigation source for the local crops of Shilin, including seasonal flowers and vegetables.
The stone path along the canal was historically used by farmers to maintain the waterway and transport harvested goods.
The Pingding Ancient Canal is a historic irrigation system located in the Shilin District of Taipei, spanning approximately three kilometers within Yangmingshan National Park. Originally constructed during the Qing Dynasty in the 1830s, the canal was designed to divert water from the Neishuangxi River to irrigate terraced fields in the Pingding area. The trail follows the stone-lined water channel, providing a rare look at traditional hydraulic engineering still in use today. Hikers walk along the flat, narrow banks of the canal, which passes through lush forest, bamboo groves, and active agricultural landscapes. The path connects the lower and upper sections of the canal, offering a glimpse into the agricultural heritage of the Taipei basin. It serves as both a functional waterway for local farmers and a recreational trail for hikers interested in history and nature.
The section where the canal runs adjacent to traditional stone-walled terraced fields and bamboo forests.
Wear footwear with strong grip, as the stone paths alongside the canal can be slippery due to constant moisture.
Bring an umbrella or raincoat, as the Shilin mountain region experiences frequent, sudden rainfall.
Carry a light snack or water, as there are no shops or vending machines along the actual canal trail.
Do not attempt to walk the trail during or immediately after heavy rain due to the high risk of landslides on the steep mountain slopes.
Stay on the designated paths to avoid damaging the irrigation walls and respect the local farmers' crops.
