An exciting railway with 86 km network of narrow gauge railway through the mountains.
The railway, originally constructed for logging, has become a tourist attraction with its unique Z-shaped switchbacks, and over 50 tunnels and 77 wooden bridges. The main line originally ran from the city of Chiayi (elevation 30 m), to Alishan (elevation 2,216 m), but is currently partially closed past Shizilu. The vegetation along the way changes from tropical to temperate and finally alpine. The line features many switchbacks on the way up the mountain
