Located at 71.5K of County Road 166, near the Rui-li No. 1 Bridge. The park has clear water quality and a serene natural environment, where you can spot wild birds, butterflies, beetles, fireflies, frogs, etc. It is an eco-recreational green trail. The trails in the park are mainly made of wooden boardwalks and stone walls. In addition to the wooden boardwalks, the trails around the mountain also feature imitation wooden staircases that are flat and easy to walk on, offering excellent scenery. The Yuan潭 Stream, which flows through the park, is located in a stratum of alternating sand and shale. Due to well-developed joints, the park features multi-tiered waterfalls and pot holes, towering cliffs, narrow gorges, steep slopes, and other unique features, making it an ideal spot to observe mid-altitude valley landscapes. Moreover, the park's environment is characterized by abundant water vapor and high humidity, making it suitable for the growth of epiphytes that thrive in humid conditions. Common trees in the park include large-leafed plants like Machilus, Benzoin, and Taiwan Zelkova. Epiphytes such as Huperzia and Asplenium thrive here. The unique terrain and environmental conditions have woven an incredibly rich ecosystem in this park.
