Bracken Cave is home to the largest bat colony in the world. Each year, between 15 and 20 million bats find sanctuary in its depths, making it one of the most vital roosting sites on the planet. These bats are primarily Mexican free-tailed bats, who journey thousands of miles from Latin America to raise their young in the safety of the cave.
