Jiayang Dashan Mountain is located in the city of Taichung. It includes a 16.1 km long mountain pass that extends outward and backward moderately and parallel to the mountain’s circumference. It is characterized by a flowing river that began to flow thousands of years ago and continues to this day. The nature of the mountain in general is difficult, and not suitable for family climbing trips due to its rugged rocky nature, its thorny plants and huge trees.
