Baiyang Trail was built by the Taiwan Power Company as construction road, and now has been rebuilt to be a flat and wide trail. It is about 2 km from the entrance to Shui Lian Dong (Water Curtain Cave), passing through 7 tunnels and takes about 3 hours for a round trip. Walking along the trail, you see unique cliffs and waterfalls. Near the third tunnel, where water runs into Tacijili River, is the most magnificent section of the canyon landscape.After passing Baiyang Bridge, you see Baiyang Waterfall rushing down from the cliff and flowing down to the lower valley. This breathtaking scenery can be view perfectly from the viewing platform.
