Covering 3% of the landmass of Taiwan, Yushan National Park (玉山國家公園; Yùshān Guójiā Gōngyuán) is in an area that sits on the junction of the colliding Philippine and Eurasian plates. The landscape is strikingly rugged, marked by thick forests, deep valleys, high cliffs and rocky peaks. Among these peaks, 30 are over 3000m, and one, the eponymous Yushan (Jade Mountain), is the highest mountain in Northeast Asia at 3952m and attracts hikers from all over the world.
Yushan National Park covers areas of Chiayi, Nantou, Kaohsiung and Hualien counties. A 20km drive west will take you to the Alishan Forest Recreation Area. From Yuli in the east, you can reach the Nanan section of the park, with its fantastic Walami Trail. The South Cross-Island Hwy, which skirts the southern borders of the park, is no longer passable.
You can visit the park year-round for hiking or sightseeing.
