Introduction to Jinshui Cave: Located at the foot of the eastern part of Tianti Mountain, it is a typical karst cave in northern my country and is known as the first water cave in North China. Jinshui Cave is more than 1,200 meters deep. There is an underground river flowing in the cave. There are many cave halls, each with its own characteristics. After hundreds of millions of years of erosion, there are various exquisite stalagmites, stone mantles, stone flowers, stone towers, etc., which resemble people and animals, or in the cave. Hanging upside down from the top, or arranged at the bottom of the cave, it is dizzying and breathtaking.
