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.

We are monitoring the evolving situation with the COVID-19 outbreak and following the recommendation from the Centers for Disease Control to limit public gatherings.

Therefore, due to the ongoing spread of COVID-19 cases throughout South and Central Texas communities, we have canceled the 2020 bat flight season at Bracken Cave Preserve. Thank you for your understanding.
