Believe your eyes, the Erwang Cave in China is so big that they even have their own weather system! I always thought this legendary cave was fake, but … no, all this actually exists! This huge cave, located in Chongqing, was actually hidden for a long time and was not discovered by the exploration team until recently. There are complete clouds, fog and a complete weather system in the huge cave, which makes it one of the amazing landscapes recently discovered. Besides, you can also observe this huge cave and see the clouds in it. Several caves have been used by nitrate miners in the past, but most of them are still undeveloped. The staircase hall in the cave extends to 12 mu of sky and is covered by clouds about 250 meters high. Like most caves, Erwang Cave has many pools and hidden areas, so explorers must always pay attention to their surroundings when walking, especially in rainy days. Erwang Cave is composed of Ordovician limestone. And its geographical location is very close to another huge cave: the Three Kings Cave.
