The alpine climbs are inside the natural reservation areas declared by Yushan National Park. People who enter Yushan National Park reservation areas need to apply for Yushan National Park entrance permission. The permission is granted only for limited number of persons daily. Sadly, in some climbing seasons (especially some Febraries in recent years, the best times for alpine climbing), the park official would reject any application for entrance permission, even if you specifically apply for alpine climbing in this area.
