This was great, our first experience with witnessing a Bat Emergence. Be sure to take the lower level and pay the modest entrance fee. The bats took a while to emerge but we witnessed over 2 million bats swirling around us before going on there evening hunt for food.

We stayed at a B&B close to Old Tunnel. One night we decided to check out the bats. We did not pay $5 to go down to the viewing area, but stayed up at the top where one of the guides explained some things about bats. We were a little out of earshot, so I couldn't hear what he said. It started to get darker and finally the bats came out. We only knew they were flying out because a kid nearby pointed it out. It was really hard to see them since we were kind of far away. It probably would have been better if we paid $5 for the better viewing area.

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!!!!

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.

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.
