The park contains more than thirty peaks over in elevation, and two-thirds of the area within the park is above . The elevation difference in the park is , and there are many canyons, cliffs, and valleys. Because of its remote location and entry control, Yushan National Park is not among the most visited national parks in Taiwan. Even so, the park attracted 1,044,994 visitors in 2015. Geology Taiwan, which owes its existence to the power of plate tectonics, remains a place of regular seismic activity. Examples of geological features such as fault lines, joints, and folding can be seen throughout Yushan National Park: Great Precipice (大峭壁) — Great Precipice (23.4683339 120.9396649) is located 1.2 km before Paiyun Lodge (排雲山莊) on the Yushan Trail. A precipitous cliff with fossils of ancient marine species and a few wavy marks in the rock can still remind us of its oceanic past. Scree slope at the foot of Main Peak Fault scarp in Laonong (荖濃) between Main Peak and Batongguan (八通關) Fuzi Cliff (父子斷崖) and Guanshan Cliff (關山斷崖) The Southern Cross-Island Highway and the Yushan Scenic Highway both offer countless opportunities to witness the area's special geological features. Hydrology Yushan is an important watershed of main river systems in central, southern, and eastern Taiwan. It is the water sources of the Zhuoshui River (濁水溪), Kaoping River (高屏溪), and Siouguluan River (秀姑巒溪). The Chenyoulan (陳有蘭溪), Jyunda (郡大溪), Nanzaisian (楠梓仙溪), Laonong (荖濃溪), and Lekuleku (拉庫拉庫溪) rivers are all young rivers from Yushan with V-shaped river beds. 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) cut through land traversed by a fault line, and 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 both visitors and animals precious water from the mountains. However, the ecosystem around
