The scenic outing passes by the Xinqiao Waterfall, which is 118 meters away, and opens up trails along the cliffs to find the water curtain cave. The water curtain cave is a natural karst cave of the Three Gorges Underground River in the Gulongshan Grand Canyon. The mouth of the cave is covered by the water curtain. The three cliffs of the mouth are covered by evergreen moss. Silver flowers are connected, and the water smoke is filled.
