Shuiyuedong is an attraction in the Elephant Trunk Hill Scenic Area in Guilin. Located between the elephant nose and the elephant body. The cave is 12 meters long, about 12 meters high, and 10 meters wide. Because the stone cave and the water reflection are like a moon, one sinks under the water and one floats on the water, it is named Shuiyuedong. There was a natural cool breeze coming into the hole and it felt very comfortable.
