Although the 16.1-acre Old Tunnel State Park is the smallest state park in Texas, it serves a very important function. There’s no camping and only limited hiking. It’s main function is to protect and preserve the colony of up to 3 million Mexican free-tailed bats and 3,000 cave myotis bats that live in the old railroad tunnel.
