Tunabana Ecological Trail Introduction
Located in Chashan Village, opposite to Kaiyuan Farm. This asphalt industrial road is quite wide and flat, with an irrigation ditch alongside. It takes about 30 minutes to walk from here to Jiayama Waterfall. The journey gradually transitions from farmland to dense forest. Along the way, the Jiayama Creek flows on the left side. The park features an O-shaped walking trail that allows you to circle the Sunset Pavilion, walk along the mountain ridge, and then proceed to the waterfall. The famous "Water and Fire Coexist" underground biogas spring area in Chashan is also nearby. In the evening, it becomes an exciting spot for night observations. There are as many as 15 species of frogs, accounting for half of Taiwan's frog species. Fireflies are also present in 6 to 7 species. Additionally, a small path next to Jiayama Waterfall leads to Dashi Wall and Bat Cave, with a journey time of about one and a half hours.
