Schedule a Bracken Visit


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 concentrations 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.

Visitation is generally reserved for Bat Conservation International Members. Members have many opportunities during the season (mid May - Mid Sep) to attend member-only events.

If you are NOT already a member, join here. A registration access code will be emailed to you approximately 2 weeks before registration opens. If you join after the initial registration access code is emailed, this code will be included in your confirmation letter.

If you are already a member – a registration access code will be emailed to you on June 1.  If you lost your code, please email This email address is being protected from spambots. You need JavaScript enabled to view it. .

Members supporting BCI with a $45 annual membership and those who have added an annual membership to an adopt-a-bat may bring up to 3 guests. Members supporting BCI monthly or with a $60 or more annual membership may bring up to 5 guests. These members will also have earlier access to register for a Bat Flight. Members may attend one Member Bat Flight at Bracken each season (1 Membership = 1 Member Bat Flight per year).
