Bracken Cave Preserve
Jonathan Alonzo

Bracken Cave is the summer home of more than 20 million Mexican free-tailed bats (Tadarida brasiliensis), making it the world’s largest bat colony and one of the largest concentration of mammals on earth. The emergence of these millions of bats, as they spiral out of the cave at dusk for their nightly insect hunt, is an unforgettable sight.

The 2021 Bat Flight season at Bracken Cave Preserve runs from June through September.

The 2021 season includes both virtual and in-person opportunities to experience the wonder of bats at Bracken Cave Preserve.
