Book A Member Bat Flight

Book A Member Bat Flight

Bracken Cave is the summer home of more than 15 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.

To book a member bat flight, you must be a member of BCI. (see note at bottom of this page for more details). 

Three types of member events are being offered during the 2019 season:
