Yuanwangkeng Riverside Park is a linear green space situated along the Yuanwangkeng Stream in the Gongliao District of New Taipei City. It functions as a primary trailhead and staging area for the historic Caoling Old Trail, a Qing Dynasty-era mountain path connecting Gongliao to Yilan. The park features manicured grassy areas, wooden pavilions, and pedestrian footpaths following the natural curvature of the stream. Its terrain is relatively flat, making it an accessible staging point for hikers before tackling the steeper elevation gain of the trail. The park includes a small stone-paved square and irrigation-related infrastructure showcasing local rural agricultural history. Water from the stream is notably clear, supporting local riverine ecosystems. The site is frequently used by families for light picnics before beginning the mountain trek.
The stone bridge crossing the stream provides a clear view of the park's lush valley backdrop and the mountain ascent.
Bring a portable sun umbrella or sunblock, as the park features wide-open spaces with limited natural shade.
Check your footwear before starting your hike, as the riverside gravel paths transition into uneven mountain terrain on the main trail.
Bring your own drinking water, as facilities within the park area are limited.
Do not attempt to swim in the Yuanwangkeng Stream, as the currents can be unpredictable and the water is protected for environmental conservation.
Practice 'Leave No Trace' principles by taking all waste with you, as there are no trash disposal bins on site.
