Old Tunnel State Park is a railroad tunnel of the Fredericksburg and Northern Railway, which ceased operations in 1942. The property came under the care of Texas Parks and Wildlife Department, and was officially made a state park in 2012. It is located halfway between Fredericksburg and Comfort on Old San Antonio Road. Since the shut down of the railway, the tunnel has become a bat cave, hosting over 3 million Mexican free-tailed bats and 3000 Cave myotis bats. The bats emerge at sunset during the months of May through October, and viewing is open to the public.

  • Great tiny State park. If you go before 5 pm you can walk down the trail past the old railroad tunnel. Pay the $5 per person, cash, exact change and treat yourself to the lower viewing area where a park ranger gives a fascinating talk about the Mexican Freetail Bats. (No small children under 3 allowed in lower viewing area) Viewing times change call the park to free number for updates. Bats in residence approximately late April through October. Take your own water, wear sneakers or hiking boots. We saw 3 million bats last night!
  • Pretty little park. We went at 4pm so we missed the bats, but could still see them flying in the tunnel warming up for their nightly flight. Walked down the trail and got to see 2 armadillos. Very cool.
