Water Curtain Cave sits to the north of Zhangtang Ravine. There is a small waterfall which flows from the top of Xiabin Cliff, which has become known as Small Water Curtain Cave. As you carry on up the river, you reach Water Curtain Cave. The roof of the cave is slanted dangerously, with the cave being deepest at its waist. The opening of the cave is skewed widely and the ceiling of the cave offers shade and coolness. Two strands of water flow from above over the hundred meter high overlying rock top, as if two dragons were spraying saliva, the water drifting between the mountains.
