15 minutes from Old Tunnel wildlife area

The Old Tunnel WMA is the smallest Wildlife Management Area in Texas, containing only 16.1 acres of land. Despite its small size, there are a variety of recreational and wildlife-viewing opportunities at Old Tunnel WMA. The abandoned railroad tunnel is home to up to three million Brazilian free-tailed bats and 3,000 Cave myotis from May to October, more mammals than any other WMA. From May to October, visitors come to watch the bats emerge from the tunnel each night, and nightly educational programs provide guests with a better understanding of the life history and ecology of bats.
