Jinshuiyan is not far from Moon Mountain, and is also in the Shili Gallery Scenic Area. It is a huge underground river cave. You can get there by taking the battery car of Shili Gallery, and the traffic is very convenient. Similar to many large caves everywhere, there are also many natural formations of stalactites, stalagmites and underground rivers in the cave. I especially like to see the stone fins hanging from the top of the cave, which are large and regular wavy curves. Although it is stone, it feels very thin and light, like the fabric of the ripples are formed by the wind. There is an underground river in the cave, you can take a boat to cross the current, unlike the experience of walking in the cave, you can try. You can also take the glass plank road by the underground riverside. Sometimes the river surface will be higher than the ground of the plank road. Through the glass on both sides of the plank road, you can see the water scene. There is also a mud bath in the hole, but the lights are dim and I don't dare to try it. The humidity inside the hole is very high, very humid, the ground is also very slippery, walk carefully.
