The underground stone forest is located in Jiuxiang Scenic Area, Yiliang County, Kunming City, Yunnan Province. It was originally called Bat Cave. It is named because most of the stalactites in the cave hang upside down from the cave ceiling and resemble bats. Also, because the stalactites grow upside down in the cave, they look like an upside-down stone forest. There are also strange rocks leaning out from the side, so it is also called the underground inverted stone forest.
