Swallow Grotto Introduction
The width of the cliff at Yanzicrack is approximately 40 meters, with the upper part featuring wavy parallel lines and the lower part displaying a concave wall about 2 meters high. A large protruding sheer wall is formed by wind erosion, displaying distinctly visible horizontal grooves and densely packed small holes, believed to have been a nesting place for swallows in the past. There is a mountain path that passes beneath the cliff, and during the rainy season, water cascades down from the cliff, creating an experience reminiscent of walking in a curtain of water.
