Introduction to Bailong Waterfall: Bailong Waterfall is the most spectacular waterfall in Longtangou Scenic Area. In the rainy season, this waterfall is more than 6 meters wide and more than 40 meters high. The sound of the waterfall is like thunder, and water mist surrounds it within a hundred meters. When it first clears up after a rain, a faint rainbow often floats under the stone wall inside the waterfall, like a bunch of colorful yarns swinging in the water, so people often call this waterfall "White Dragon Crouching Rainbow".
