Shei-Pa National Park is located some 100 km north of the Tropic of Cancer. The park covers a wide range of ecosystems between 760 meters at the lowest point, the Da-an River Valley (大安溪) and 3,886 meters elevation at the highest point, the top of Xueshan (雪山主峰). Xueshan is the second tallest mountain in Taiwan. The Xueshan Range is located along the northern end of Taiwan's Central Range. Like most of the mountains of Taiwan, the Xueshan Range mountains are an uplifted metamorphic belt that makes up the spine of the country. Notable geologic features of the park include the box fold of Pintian Mountain as well as many glacial cirques.
