About Old Tunnel State Park

Old Tunnel State Park is a small Texas Parks and Wildlife property in Kendall County, on Old San Antonio Road between Fredericksburg and Comfort. It is the state's smallest state park. From May through October, a large colony of Mexican free-tailed bats and a smaller group of cave myotis roost in an old railroad tunnel, and visitors can watch them leave at dusk during ranger-led programs. Bat-viewing tickets must be bought in advance, since the park opens to ticket holders after 5 p.m. during bat season. Outside those hours, a short nature trail offers wildlife watching, birding, and railroad and bat history signs. Visitors must bring their own drinking water, and camping, pets, and smoking are not allowed.
