, and is classified as a metamorphic complex area of Dananao on the geological map. Because there are very few coastal cliffs in the world that exhibit such a great elevation drop, the natural landscape of "high cliff valley" makes Qingshui cliff a rare coastal cliff. The coast of the Qingshui Cliff is continually beaten and eroded by the sea water of the Pacific Ocean, and the rock walls on it are subject to natural forces such as earthquakes and typhoons. The beaches below are full of different sizes of marble stones, from giant boulders to grains of sand.

Transportation
