Thousand-Year Bat Cave Introduction
The rock walls of the Bat Cave are an extension of the upper geological layers of the Swallow Cliffs, stretching over 200 meters. The rock type is stratified sandstone and shale, with honeycomb-like openings formed on the rock surface. The largest opening is about 50 centimeters wide and 60 centimeters deep, which was once a habitat for bats, hence the name "Bat Cave." Unfortunately, the bats have long since disappeared.
