Introducing Nenggao (Neng-gao/Nengkao) Cross-Island Trail
This 200-year-old high-mountain trail (Nénggāo Yuèlǐng Guójiā Bùdào) was first used by the Taiya to help them ply their trade between Puli and Hualien. During the Japanese occupation it was expanded and used, ironically, to police aboriginal tribes. During the later half of the 20th century, the path was expanded further by Taipower, which used it when laying high-voltage power lines.
For strong hikers, it is possible to hike from Nenggao to Hehuanshan. Usually three to five days are required.
