Hushan (Mt. Tiger) is one of the low elevation mountains inside the Sishou Mountain Citizen Forest Area. It is 140 meters above sea level and forms a natural barrier at Taipei City's southeastern section. The terrain is high on the west and low on the east， and on its peak is a sundial for observing the movement of the sun. The path is paved with sandstone and shale. Hushan River passes through the mountain， and forms an excellent natural habitat for the nurturing of fireflies， frogs and diversified life forms， making this trail the best spot for observing a wetland natural habitat. Along the path are also clear indicators and maps. This is an ideal place for both hiking and ecological observation.Sishou Mountain Citizen Forest The Sishou Mountain Trail was renamed Sishou Mountain Citizen Forest after having undergone renovation.
