An easy 2-km, 45-min walk from the park office at Lushui to Heliu. Winds around short cliffs above the main road. Does pass through one dark tunnel, so bring a flashlight.
九曲洞
水簾洞
An easy 2.1-km trail, 2-hr round trip. Named for the cave at the end of the trail, where water literally pours down in sheets from the roof. Pack a poncho or use one discarded by other considerate hikers (or inconsiderate, depending on your point of view). Hiking to this point on the Baiyang Waterfall Trail takes you through many very long, completely unlit tunnels — an experience in and of itself. Be sure to take a torch/flashlight, or you'll be walking in pitch black darkness. The first part of the trail is wheelchair-accessible.
5.5 km, 5 hr.
Yanzikou Trail
1.37 km, 20 min. The Swallow Grotto is a short easy walk along very nice views of the gorge, finishing under the impressive Zhuliu cliffs. Kiosk with restrooms available halfway. Closed as of December 2019.
