It is situated in the Chinese tourist city of Guilin. The largest and most picturesque of karst caves. But the colorful name of this ancient cave - nothing compared to the beauty of its halls. This karst cave goes back 240 meters and the first tourists visited it ... 1300 years ago. The route length is about 500 meters, which in turns provides breathtaking picture of bizarre formations of stalactites and stalagmites, piles of rock formations and stone pillars. The cave was formed as a result of the destruction of quartz rocks with water.
