Introduction to Longtan Waterfall: The forest is dense and the valley is deep. The Yujia River is winding and ups and downs, and the ratio increases, forming a series of waterfalls. Among them, the largest first-level drop is 10m. The waterfall falls and forms a deep pool. The sound of the water is like thunder. The boulders on both sides are rugged and the cliffs are steep. It is deep and quiet. It is a good place to escape the heat in summer.
