This is one of the coldest places in Hangzhou during the summer - it's 20 degrees Celsius at the entrance of the cave, about half the urban area's high temperature.Temperatures in the innermost area of the cave drop to 10 degrees, so bring a coat.
The cave is situated in the middle of Yuhuang Mountain. It's not a natural cave but was excavated during the Qing Dynasty (1644-1911) by priests from a nearby Taoist temple as a summer retreat and a place to practice spirituality.
