Tuna Banas Ecological Trail Introduction
Located in Chashan Village, opposite of Kaiyuan Farm, this wide and flat asphalt industrial road is accompanied by an irrigation water channel. It takes about 30 minutes to walk from here to Jiayama Waterfall. The path gradually transitions from farmland to dense forest. Along the way, the Jiayama Stream runs on the left side. The park features an O-shaped trail that allows visitors to hike up to the ridge at Sunset Pavilion and then proceed to the waterfall. Nearby is Chashan's famous "Water and Fire Coexistence" underground biogas spring area, which is also an excellent location for night observation. There are as many as 15 species of frogs here, which account for half of Taiwan's frog species. Additionally, there are about 6 to 7 species of fireflies. Furthermore, a small path next to Jiayama Waterfall leads to the Great Stone Wall and Bat Cave, with a journey time of approximately one and a half hours.
