Twelve Longtan Waterfall is one of the main attractions of Beichen Mountain. It is a five hundred-meter-high stone cliff from the clear spring outside the water sky cave. It falls down layers, through different heights of crack steps and stone caves, and accumulates into twelve clear water pools with visible bottoms. Because the waterfall is not much, like a silver bead string. Looking up at the waterfall in the "bottle table", it is shaped like ginseng, so it is also known as the "ginseng waterfall". The size, shape and depth of the pool vary, but they are all clear and clear. The fifth pool is the largest, with a surface diameter of more than 3 meters and a depth of about 2 meters. Standing between the eighth and Jiutan, looking up at the gap, the waterfall is connected to the sky and the mountains and rocks. The water seems to be falling from the sky, and the scenery is very magnificent! There are often people who love outdoor activities, and they go to the stream to play, both viewing and fitness. By the way, the eight immortals of Beichen Mountain are also very beautiful.
