This was my first trip to Fredericksburg, Texas and we stayed in a B & B on Main Street. We got a map of the area and this was on it so we wanted to check it out. We arrived at the park, parked in the lot and walked over to the viewing area. We each paid $5 (WELL WORTH IT!) and walked down to the lower viewing area that is open on certain dates. We went on a Sunday night. When we took our seats, a park ranger or someone that worked at the park, went through a whole tutorial with photos on bats and a bat emergence. It was so cool, I've never really thought about bats or cared to learn about them, but I loved the intro they gave! We sat there for about 10 minutes while she talked, and then the bats started emerging around 8:51 pm. We were BLOWN away there were SO many bats! It was one of the coolest things we've ever seen.The emergence took about 15-20 minutes and we were able to see them on the lower level. It got a little dark but we still got an awesome video!!! You have to do this if you are in the area!!!!

“Lots of Bats!”
Reviewed July 14, 2013

Had been wanting to go here for several years and finally got to and was not disappointed. Nice roomy parking, nominal fee if you want to sit close to bat emergence and volunteer park staff give you lots of info on the bats and tunnel history. It is a sloped walk down and you sit on rock steps but not bad. Lots and lots of bats and a site to see. Located off the beaten path but there are some really neat cabins, Walnut Canyon Cabins, to stay at close by. The staff is friendly and informative.

“Couldn't see anything”
Reviewed July 11, 2013 via mobile

So...we arrived here around 7:20pm as advised by reviews (current viewing time when we were there projected to be around 8:52pm) and the Lower seating area was already sold out. Apparently there are 70 spots available and I would suggest you get there very early to get access to the Lower area. We ended up leaving because we were told by the park ranger that unless you get Lower seats, can't see much from the Upper seating area because it gets dark. Lower area is $5, Upper is free.

With that said, we visited on Saturday after July 4th...so weekend and holiday probably makes this place very busy.

Also, there is a bar/grill located within walking distance of this place so if you get here early grab food or beer.

Also, sign posted no pets. We brought our dog because we weren't aware of that restriction (didn't see it anywhere online).

I may edit the rating once I'm actually able to visit and see something but until then, this is it.

“Not the same as Congress Street Bridge”
Reviewed July 6, 2013

I enjoyed the scenery. It was a nice night and enjoyable to be out. We viewed from the upper viewing site. I never saw the bats. My husband said he could see them. I guess I expected the same spectacular show you get at Congress Street Bridge in Austin and I definitely didn't get that! I will revisit and next time I'll sit in the lower viewing area. I'm sure that will provide a better view.

“Great place to see the bats”
Reviewed June 25, 2013 via mobile

Some reviewers have complained about the smell, the price or the time that the bats emerge. Get over it! You should be honored to have the opportunity to see such a spectacle of nature. The money is well spent on bat conservation which benefits all of us. If your are upset about the time that the bats emerge, well, you'll have to talk to the bats about that. And they'll poop all over you in the process so that you will smell just like them.

Seriously - look up Old Tunnel's web site, call the number on the webpage to get the most recent bat emergence info and LISTEN TO THE ENTIRE MESSAGE for helpful info (like they can't offer chance for the admission fee).
