My family loved this experience. Get there on time so that you get a ticket for the bottom viewing area which offers a much closer and interesting experience. You can take light snacks down there but people didn't seem to have patience with wrapper or plastic bottle sounds so you may want to make sure you take something that doesn't... More

If you are expecting a well manicured park skip it. If you want to see Mexican free tailed bats, in native (well, man made but never used )habitat, by the millions fly out of the tunnel at sunset then you will like this park. Always call ahead to find out what time the bats have been leaving and arrive an... More

If you want to visit Old Tunnel State Park to watch the bats, make sure you call ahead for updated information. We went in late July and only saw a few flying around, not the mass exit. We were told the bats would not come out until after dark because it was too hot, in the high 90s. Best time... More

The bat cave was great. Went with friends and got there an hour before dusk and that was a little to late for a good seat. Had to sit in the middle area, it's an area reserved for handicapped people but there were none that night so they let us sit there. Bottom deck was full even an hour early.... More

This very small state park is primarily visited to observe the bats that emerge from the old abandoned railroad tunnel at dusk. There are stands set up at various levels, with a small charge for the lowest level closest to the tunnel entrance. During the daytime, you can look into the tunnel and see the bats milling about. You cannot... More

Insider tip.....are you listening?? Do your research, but I'll help y'all out here, lower deck ticket sales ($5 a ticket) start at 5:30 pm and is limited, first come first serve. Buy early and go grab a bite over at the Alamo Cafe (in another review) or bring a picnic. Bring exact $ because they can't make change. In the... More

Last week (7/22) we drove out mid afternoon after leaving Luckenbach but didn't want to drive back that night to see the bats so we thought we walked around & read the posted boards with the bat information. We found the gate open & unlocked so we walked down to the tunnel opening. It's about 1,500 ft down & the... More

Pay the $5 to view from the lower deck. The ranger presentation was awesome... She really provided a very informative and entertaining talk. Bats came out at 8:52 and even had several flying through the crowd. Awesome experience that can't be described without being there.

This is a really cool spot in central Texas were you can get close to the bats. The park is the smallest park in Texas so there is no camping and really nothing to do but see the bats. We went out at around 6 to get our tickets, which are five dollars cash only, and then came back at... More

Guests are only allowed down to the lower viewing bowl on Thurs-Sun night only. We went on a Wed and it was too hard to see the bats. Other than that, the place had nice views and the park rangers shared some good bat info.
