The Bats of Bracken Cave

It may not be Transylvania, but that isn’t stopping Bracken Cave from hosting the world’s largest bat colony!

Bracken Cave

This rocky cave near San Antonio, Texas is home to more than 15 million Mexican free-tailed bats. Once wild land, Bracken Cave was purchased by Bat Conservation International in 1991 to prevent urbanization threatening to take over the area. The organization now owns nearly 1,500 acres of land around the cave, ensuring a safe habitat for these tiny winged mammals.

The Inhabitants

Each year, expecting bat mothers return from wintering in Mexico to give birth in the safety of Bracken Cave. When the pups are born in late June, Bracken Cave’s bat population nearly doubles in size. In fact, it’s estimated that there are 500 bats per square foot gathered on the cave walls during this period.

While the mothers go out hunting, the infants are left in a nursery-type setting. Amazingly, each bat mother is able to locate her child among the millions of others using her incredible sense of hearing.

Visiting Bracken Cave

To protect the bats, visits to Bracken Cave are available only to members of Bat Conservation International. Membership costs $45 for an individual to bring a group of up to four people (including the member), while $60 and up memberships allow up to six people per group.

For those lucky members, they can visit once per season between May and September, with the best months being July and August. These visits include a 2-3 hour guided tour with amazing views of the bats exiting the cave at sunset.

Special member tours are also offered, including Camp Overs and Morning Return tours.
