September 2020— Enchanted Rock advises me to go here when my reservation wasn’t found. If you are not in the area and aren’t going that way, you may not find it worth your whole. It does not compare to enchanted rock trails. There is one short trail. Beautiful views but it’s not going to be a day in nature. More like an hour or two. There is a beautiful trail and view. They have tours but not when I was there. I also think pets may not be permitted but I’m unsure.

It was a nice little drive through the countryside. The staff were very courteous and informative. They put safety first, including asking if we were comfortable with the guide having his mask off outside while standing several feet away.Of course seeing the bats leaving the tunnel was the best part. They put on a beautiful show.

Small park with a short hike and an interesting local history. Great for spending an hour or so outside after breakfast, lunch or before dinner. Kid friendly hike as long as they are steady on their feet. Would recommend for a short outing. Unfortunately werent here at the right time of year to see the bats exiting the tunnel.

Hidden gem. The state park is free and is very well maintained. They have information on the history and nature of the place.Its a short trail, you can go through it relatively quickly. There were many bats you could see inside the tunnel and they have bat watching events later on the day when they come out.Beautiful view.

Place was fairly empty. Like other reviews state...its a small trail. No bats when we visited but it was nice.

It has a nice trail to walk which has alot of shade. We were there during the day so we didnt get to watch the bats come out. Its a nice walk if youre in the area.

Great small park with short trials and lots of shade. The bats make for an interesting smell.

Really neat, lots of bats @ dusk. Limited tickets obtain early. Otherwise watch the bats and have a great hamburger @ the best hamburger in Texas 100 feet from the entrance.

Even though we couldnt get reservations for the bat viewing (severely limited due to Covid), it was a lovely way to spend a few hours during the afternoon. Its a tiny park and unstaffed, but has some nice shaded trails. Looking through the tunnel we could see some bats flying around, evening in the middle of the day.

Awesome little park with a short hiking trail. Really cool to catch the bats flying in right at sunrise.

We went during the day to check out the tunnel. It was a bit on the stinky side, but pretty neat to look at. The overlook was pretty even for winter time. The stairs are on the steep wide side, but it was still a nice walk and another way to enjoy the outdoors.

Nice little park, off the beaten path. Wasnt there for the bats, but nice picnic area with good views and a steady breeze.

A short hike from the parking lot...a little steep with loose gravel...and worth every step. Its a quiet and lovely spot. Visited during Covid-19, there were not many in the park.

Got to see the Mexican bats fly out. The state park ranger told us that they usually fly away from where we were, but a gust of wind came in right before they started flying out, and they were flying really close to us. It was a great time spent.

Trails to walk down along the railroad. Pretty steep descent. Once at the bottom, there is a bridge where you can look through the 923 foot tunnel from about 50 yards away and see a few bats flitting between the tunnel walls. Trail closes at 5 pm, after which you must have an online reservation to be in the viewing area for the evening emergence of the bats.

Amazing! To be able to see millions of bats come out of the tunnel is impressive! Be sure to watch for deer on the way, we saw over 200 in 12 miles!

A good, free state park if you are passing through or staying close by. As of June 2020 there is some construction going on in the parking lot but everything is still accessible.It is a great place to get out, walk around, and get some fresh air. They have a wonderful nature trail down a hill with some information on local plants and birds to look for. It is not a hard walk at all. But make sure you have water in the summer. There is also a garden and some picnic benches at the entrance.There are multiple areas where bar watching is available for a fee. We did not come for the bat emergence as we came during the day time. If you call the number for the park you will get an automated message with information on bar emergence time and cost.

Went for a discovery drive down 290 wonderin a bit about this bat cave. Already knew tickets for the whole weekend were sold out, but wanted to see what the area had in store. Found a beautiful hike along the trails in the park. Free to do that and oh, how beautiful it is! Got quite the workout as it turns out and how we needed it. Not crowded at all and the few people who were there were indeed glad to see other people. Will definitely come back to view the bats at night in the near future.More to follow...

Watch millions of Free-Tail Mexican bats rise into the evening in a bat-nado. Its a peaceful and exiting experience all at once.

You can see the bats flying around inside tbe tunnel anytime. You cant see them up close or outside the tunnel until eveni g. The trails are short and doable.

Went with my family to watch the bats emerge from the old train tunnel. It did not disappoint! The bats were coming out early because the juveniles were ready to fly which was increasing competition for bugs. They started around 7:45.If you go, make sure you pre-register. They have no means of registration at the state park.

Great little park. Even of you dont stay for the bats, there are little trails to take to spend a few hours. Also, Alamo Springs Cafe is right next door for a bite.

Great place to view bats exiting the cave at dusk, you can also see them flying around in the cave before dusk if you follow the tail. The trail is a bit rough i dont recommend for small children unless they are being carried.

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.

Our family had a great time at Old Tunnel State Park! The volunteer at the upper viewing entrance was a little stiff, but efficient. The volunteer at the lower viewing area was friendly, animated, and knowledgeable! It was a nice cool breezy evening and the bat emergence was spectacular! A few bats flew in our direction adding to the excitement! We arrived closer to dark. It would be worthwhile to arrive earlier and explore the park a bit. It’s a bit of a country drive from San Antonio. Take your time and plan accordingly especially when driving home in the dark! Bring water and snacks, as amenities are limited, if available at all. We didn’t encounter any mosquitos, but it would wise to bring repellant with you just in case. The only bathrooms were portable toilets. We enjoyed our visit and plan to return again!

A very cool place to see 3 million bats coming out of a cave to feed around 7:30 at night for 30 minutes or so. It is truly a sight youll never forget.

This is the Bat Emergence at Old Tunnel State Park in Fredericksburg, TX. Definitely worth a visit. We were there last night and around 3 million bats came out of the cave for water and food before they make their trip back to Mexico in around a month.

So cool!!! Approximately 4 million bats excited the tunnel at exactly 7 pm- Quite a sight!!

Come here to see the bat colony! Purchase tickets for the lower viewing area and get an up close and personal view.

Beautiful scenic area with a distinct natural smell. We were able to see the bats active in the tunnel even with the sun up.

This is a really cool place to go check out. The drive there is neat in itself because youre driving on roads that wind up in the hills. We saw wild deer all over the place just grazing near the roads. The actual park is beautiful. Great view of everything. Its 5 bucks to go down near the tunnel, to see the bats. We didnt get to see them come out but it was okay, the views and trails were worth the drive anyway.

Nice and short trail. Perfect with kids.

Its such a peaceful and tranquil place. I was amazed as to how many bats fit in the tunnel. I definitely will be going back!!

A good short and moderately challenging trail with great uphill work

Beautiful park! The trails are beautiful and easy for beginners. The drive down there is gorgeous as well, especially around sunset. Would highly recommend!

Quiet, relaxing, free to see, not a lot of people, saw tons of bats in the cave.

Awesome experience! the guy talking before the emergence was great. answered questions very knowledgeable

Nice trails to walk, lots of steps! Saw the bats through the tunnel!

Neat place. The trail was a little hard to find, and I know it wasnt just me because I explained where it was to several people after I found it (if youre looking out at the scenery over the seating, its to your right). Nice walk, I enjoyed seeing the names of the plants. Plenty of parking. Dont expect a pit stop, bathrooms are closed most of the time.

It’s really good for such a small park. I must say, that the cave is really awesome, but the tour guide just makes it so much better. There are a lot of state parks in Texas, though, and I wouldn’t say that this one is worth to go out if your way for (if you’re a local you usually goes to state parks, however, this is a good choice).

We went during the day, which meant we could see the bats buzzing around inside the tunnel but not see them leave. It is definitely worth a visit for the sundown egress. Plus, theres a cute little cafe around the corner with good coffee and great service.

What a great night, we felt comfortable with social distancing too. Our presenter Dale was excellent and very knowledgeable. We will certainly have to go back one day

Small park. Went to see the Bat Cave . Wasnt alot of bats . I was definitely underwhelmed. Its certainly not like the Austin bat caves . Small park and not much there overall.

Interesting, good scenic short trails.

Interesting place! Has been a few years now since weve been there but was neat looking through it and seeing the bats swarming in the middle of it during the day time! A good extra stop for a road trip for sure!

A nice out if the way spot. The amphitheatre they have to watch the bats offers a great experience. There was plenty of seating and the staff onsite were knowledgeable and friendly.

Volunteers know their Mexican freetail bats and then some. Spectacular site of bats emerging from old train tunnel that was shut down in 1942. Upper viewing area is free to the public with lower area available for close up viewing for $5 each. Dont miss this amazing site which only happens May -Oct.

Best tour guides in the state!!

While I was there, 3 million bats were in the tunnel, being able to see them emerge was amazing. I enjoyed it two nights in a row. I would absolutely recommend attending.

Nice short hike. Beautiful drive to get there

Awesome state park with one of the very best bat viewing experiences around. Get there early and you can sit on the lower deck and get really close! Alamo Springs has some of the best hamburgers in the State right across the street too

Its a tiny state park, we walked the whole thing in less than 30 minutes. But stay for the show. I didnt think it would be as cool as it was. The staff is knowledgeable and super friendly. Probably the cheapest entertainment around this part of Texas.

This place has always been super quiet and even though we have never been there at the right time to see the bats we enjoy the overlook and the trails.

This place has a spectacular view!

Neat old tunnel, but not much else here. Worth visiting once.

Interesting site to see the bats and a pretty place, but restrooms are locked unless the presentation is happening. A quick stop-and-see otherwise. Cash only for the lower site to see the bat presentation.

The Bats were everything they advertised. 1.3 million bats swarmed out 20 minutes before their estimated time.Get there early about 5 pm to get tickets to get lower and closer to the old tunnel. The Rangers said they sell out in 20 minutes. $5 per ticket. We were in the bleachers, enjoying the view and the breeze for free. If your in the area this is a must see.

Super cool bat emergence experience

Nice Area to watch bats and a good day hike.

It was wonderful for all kids and adults too... Just be ready for a lot off walking and going up and down stairs and paths... Could get rough at times for some people.. But what a great lifetime experience for all of us...

Very fascinating. Free in upper deck. Employees very informative. Restaurant nect to place was sold out of food.

The people who work here are extremely nice and know a lot about the history and area. Worth the wait to watch the bats, and theres a beautiful walking trail with plenty of shade.

This is definitely a really cool place to visit. It has a very brief half mile trail.

Wonderful little hike... Informative placards and beautiful plants and wildlife... We even saw an armadillo! We will come back for the bats...

Check it out. Bats arrive in May.. but stop anytime. Beautiful park. Good restaurant there, too

Although we didnt stay long enough to see the emergence we did see some bats flying through the tunnel. The trails were nice and we had fun.

This was a great piece of Texas history that we found by chance, after seeing a sign on the highway. Glad we had some time to kill, and followed the farm road to a unique piece of Texas history.

The volunteers presentation was excellent, but the bat emergence was awesome!! Get there early and pay the $5 fee for the lower viewing area. Well worth it to see over 3 million bats heading out for their evening adventure!!

Well kept and maintained park. The park rangers were SO nice and helpful! Lots of info and displays on the bats. And when the bats come out, truly magical. A must see if you are in the area.

Interesting place of local history. Short walking trail with steep elevations. Didnt hang around for bats to leave tunnel.

Too early to see bats but Park Rangers very nice and shared some great stories and history

Beautiful place, try go in the morning to see the bats returning to tunnel. Its bit cold here so go prepared. Carry a binacular. While going in the evening, carry a flash. Best time is August/September.

What a fun and amazing place to visit. Want to go back with the grandchildren.

Love it, so relaxing. Nice hike too.

Ive been coming to this park since I was a little boy. Long before the nearby burger place existed. Its relaxed, and quiet. A great place to end the day

Amazing! Must see to appreciate!

Nice little walk.

Very interesting place to visit. Great exercise doing the nature walk.

Beautiful. Worth the drive.

Extremely underrated state park, important side to South Texas history due to the railroad that used to go from Fredicksburg to San Antonio.

Short walk with beautiful views!

Cool place will return at night

Volunteers were very knowledgeable and the park has some cool history. Restrooms were open all evening and trail was open til 630. I recommend summer months when there is more light, they started emerging around 720. Even in low light the swarms of bats were impressive. It is well worth the $5 activity fee to sit at the lower deck.you are so close to the tunnel that some bats fly right over your head. There are also two restaurants very close to the park in case you want to grab dinner.

Very nice trail. Bring plenty of water. You can visit this park at night and watch the bats.The restrooms were bot available to use during our visit, but they did have portable restrooms in the parking lot.

We loved it ..so beautiful! Be back this summer

The bats flew out around 8:50pm and it was amazing! We saw 1 million bats. Literally! The upper viewing area is free and a great location to view them leaving the tunnel.

Plan your trip. The bats leave at different times, and August is best to observe while the sun sets. October is too late and they leave in the dark.

Amazing bat emergence in the summer. It is worth paying to go to the lower observation area.

Off the beaten path, this state park is something you dont want to miss if you have any interest in nature! The guides are very informative, and to catch the bat emergence is an amazing experience! Strongly recommend!

Great wildlife and short hike all plants and trees with great identification labels...

Great surprise to find this park. Nice views and a hike path down the hill. Wish there was better parking, when busy on the weekends.

Watching the bats emerge was awesome, and the Ranger presentation before that was very informative.

Spectacular... the emergence this night was the best of the season to date. Dale was very knowledgeable and explained all very well. Worth the drive and nominal cost

Quick shirt trail. Good depth to the hike.

This is a cool place! We will be back during bat season !

No bats in March. Nice short hike. Clean and informative. I can only imagine what it will be like in May when the bats swarm out of the tunnel. If I get the opportunity I will come back.

There are a lot of bats...millions of them! Interesting view and knowledge of the day

Great place to get away and hike around.

Awesome. Bats came out at 2100 hours .
