The Baiyang Waterfall Trail is characterized by the number of tunnels. Beginning with the entrance tunnel of 380 meters (by the Central Cross-Island Highway 900 meters west of Tianxiang) to the last tunnel before Water Curtain, you will pass through seven tunnels along the 2 kilometer trail ( the 4 km round trip will take about one hour and a half).
Some of the tunnels are as straight as a pencil and you can see the light at the end. Others however are curved such that you will be enveloped in pitch-black darkness for a short time unless you take along a flashlight, which is advisable. Looking out of the tunnels from within, the lovely green mountain view is like a painting by a master. The trail was originally built by Taiwan Power Company in 1984 during the early stages of their plans (approved for construction in 1979) to develop hydroelectric power in the area, plans that included damming many parts of the gorge. The hydroelectric project for this area was eventually cancelled. Taroko survived and a road left that makes it easier for us to get into this once remote area.
The ground rock after Water Curtain (Shui-lian-dong) is loose and there is danger of a collapse so as present visitors are only allowed to the entrance of the first Water Curtain. Water curtain is a special scene created by spring water falling from the tunnel roof. Unfortunately, the danger of roof collapse means that the other water curtains are out of bounds.
