Jinmentong cliffs (金門峒斷崖) is a unique landmark along the Chenyoulan River (陳有蘭溪). It was formed when Chenyoulan River (陳有蘭溪) cuts through land traversed by a fault line, it showcases one of the best examples of headway erosion. Jinmentong cliffs (金門峒斷崖), Yunlong Waterfall (雲龍瀑布) and Yinyu Waterfall (乙女瀑布; also known as 七絲瀑布) are some popular scenic points in the park.
Alpine lakes such as Dashueiku (大水窟), Tafen Pond (塔芬池), Jiaming Lake (嘉明湖), and Tienchih (天池) are formed from rain and melting snows in the shadows of surrounding mountain peaks. These lakes provide animals including visitors precious water from the mountains. However, the ecosystem around them is fragile and need further protection.
