Quite disappointed that we drove all the way out here, and it is closed for the off season. The restaurant was open, but everything else is not. Nothing on TripAdvisor stated that their season is May-November. That would have helped and saved us a wasted long drive.

Viewed hundreds of thousand bats late in the season on Oct 31. They usually move south to Mexico by now but warm fall delayed migration. The Texas Park's volunteer, Dale (Gig Em), was on site to record activity and he gave us a lesson on bats and the railroad tunnel. Go to website for seasonal activity - I think April... More

A wonderful experience to see (and smell) millions of bats as they emerge for their evening feeding - better viewed during dry cycles when the bats emerge earlier in the evening.

Cannot emphasize enough how much I enjoy coming to this place. The bat colonies in Austin and Houston simply don't compare to the show these bats put on when they leave for their evening activities. You'll be mesmerized watching these guys as they rise like a giant plume into the night sky. The last time we visited the bats came... More

My wife and I happened onto this small but distinctive park enroute to Alamos Springs Cafe just down the road. After our lunch we stopped by and were astounded at what a neat gift of a park this is and that we hadn't heard of it at all before. Being mid-day we opted not to spend the $5 each to... More

The park is very out of the way. The country road is dark and it could be a problem at night. This is a pouplar stop and if you want the prime seating and a $5 cost per seat get their early, at least an hour before sunset. The prime seating is just above the tunnel entry. The tunnel was... More

Pay the five dollars (cash only) to see the bats at the lower level. Call ahead and get the approximate time that the bats come out of the tunnel. We got there early and were able to walk down to the bridge across from the tunnel and saw the bats swirling. I thought that might be all that we would... More

We went twice to see the bats emerge! There is a number you can call for the approximate emgergence time, which can vary. Be there early because the bats might come out earlier than expected. Plus if you are there early a park ranger will be giving an interesting talk (with pictures) about the bats and there is a question... More

make sure you get there in time and I bet the VIP spot is worth the ticket price because there are LOTS of bats that come out
