Tunaba'ana Ecological Trail Introduction
Located in Chashan Village, opposite Kaiyuan Farm. This asphalt industrial road is quite wide and flat, with an irrigation ditch beside it. It takes about 30 minutes to walk from here to Jiayama River Waterfall. The path gradually transitions from farmland to dense forest. Along the way, to the left, Jiayama Creek flows by. The park features a loop-shaped walking path, allowing visitors to walk up to the ridge of Xiyang Pavilion and then proceed to the waterfall. The famous "Water and Fire Coexist" underground biogas spring area in Chashan is also nearby, making it an exciting spot for nighttime observation. There are as many as 15 species of frogs, which account for half of Taiwan’s frog species. Additionally, there are 6 or 7 species of fireflies. Furthermore, the trail next to Jiayama Waterfall leads to the Big Stone Wall and Bat Cave, with a journey time of about one and a half hours.
