Nature

Old Tunnel State Park is the smallest state park in Texas, consisting of only 16.1 acres of land. Despite its small size, there are a variety of recreational and wildlife-viewing opportunities. The abandoned railroad tunnel is home to up to 3 million Brazilian free-tailed bats (Tadarida brasilienses mexicana) and 3,000 cave myotis (Myotis velifer) from May through October.
