In the amphitheater at the Natural Cave Entrance (off a short trail from main parking lot) a ranger discusses the park's batty residents before the creatures begin their sundown exodus. The bats aren't on any predictable schedule, so times are a little iffy. Ideally, viewers will first hear the bats preparing to exit, courtesy of an amplified frequency calibrated to human ears, followed by a vortex of black specks swirling out of the cave mouth in search of dinner against
the darkening sky. When conditions are favorable, hundreds of thousands of bats will soar off over the span of half an hour or longer.
