Take a guided tour for an up-close view of Bracken Cave as millions of bats spiral out on their nightly insect hunt. Bracken Cave is home to the world's largest bat colony and it is believed the Bracken bats represent the largest concentration of mammals on Earth.

This program is newly opened to the public in an effort to raise awareness of these amazing animals
and their importance to our ecosystem.
