The largest colony of bats in the world makes it home a mere 45 minutes away from downtown San Antonio at the Bracken Cave. Each year from March to October, the 15–20 million Mexican free-tailed bats emerge from the cave for three to four hours of feeding. The insects they eat keep crop pest populations low, which helps local farmers.
Bat emergences like at the Bracken Cave can be seen at 10 different locations around Texas including Stuart Bat Cave at Kickapoo Cavern State Park, Devil’s Sinkhole State Natural Area, and Old Tunnel State Park, to name a few.
Two years ago the Bracken Cave preserve was being threatened by a 1,500-acre housing development. Bat advocacy organization Bat Conservation International teamed up with the Texas Nature Conservancy, the City of San Antonio, and Bexar County to purchase the land, so it is now indefinitely protected.
If you’re a Bat Conservation International member you can visit the Bracken Cave on special member nights from now until the end of October.
