Millennium Bat Cave Introduction
The rock walls of Bat Cave extend over 200 meters from the upper strata of Swallow Cliff. The rock is composed of layered sandstone and shale, with honeycomb-like openings on the surface. The largest opening is about 50 centimeters wide and 60 centimeters deep, which used to be a habitat for bats, hence the name "Bat Cave." Unfortunately, the bats have long since vanished.
