Aotai trail is one of the most famous hiking route in China. It's on the ridge line of Mt. Taibai, which lies between north China and south China. Most part of Aotai Trail is extreme challenging alpine trail, 54km(33.5mi) in total, average elevation is about 3000m (10000 ft), elevation gain 4350m (14271ft). The numbers seems not much but the trail condition is really hardcore.
