Easily accessible from 35, this is an adventure suitable for the young and old. There are different levels of experience, you can be challenged or just explore. Open since the 60s, this is a spectacular peek into the underbelly of nature. Our guide shared a lot of science and kept us safe and amused. Highly recommend. I would give this five stars but the exit phase was swift and our guide never looked back to see if any of us were struggling.
This was more interesting and fascinating than I thought. I enjoyed my tour with Myles. The parking lot is very large. Plenty of parking. The tour to the cave is about a mile round trip. I don't think you can take kids strollers on the tour. And you should be in capable condition to walk the distance. The walk back is more upward, some areas are steep. It is humid as you get down, which I thought it would be cool underground. I had curly hair going in, came out with straight frizzy hair. The tour guide stops along the way and talks about the rocks, the forms, and some extra surprises along the way. The guide will also take a photo of you and your group, and you can purchase the picture at the end when you go back to the gift shop. Myles was a great tour guide. He explained everything so well. Answered questions we had. Friendly and knowledgeable. Was a very nice hour or so tour. Well worth the time and drive there. Happy I did something new and a little adventurous.
Thing Two's scout troop came here a few weeks ago to get a tour of the caverns and to earn a merit badge specifically for the Geology merit badge which can be fully earned in one day. The scouting tour starts when the cavern opens to not only allow scouts to explore the caverns for the geological aspects but also to fully cover all the requirements of the merit badge. When the merit badge is complete, the group breaks for lunch. It should be noted that full lunches are not served here but snacks are available for purchase. After lunch the scouts are afforded the opportunity to explore outside and collect rocks from the cavern. Aside from the education that the scouts get when here, that it's a wonderful place to cool off and learn something in the hot summer months as the temperature inside the caverns are 72°F (22°C) year-round. #getoutandexploretexas
My team and I went on an excursion with this one while on a business trip. We had a blast learning about the geology and history of this cavern. Our tour guide was very helpful and interactive. I would recommend this visit for anyone in the area and on their journey to and from Texas.
Stopped by on the way back to Austin and didn't know there are caves in Taxas. Curiosity got us here (since we got kid). Quite unique and interesting tour and the things we learned from it. The tour guide is very accommodated, knowledgeable and nice. The cave urself is quite fun to walk through it. And nicely down with the lighting, it added a unique & curiosity and mystique to it. The kid loved it plus it's cooler down there than outside and great break from it and the driving for sure.
Although not one of the larger caves in the US, the tour isn't bad for those who are interested in caves or have a couple hours to kill. It's an easy walk and you cover about a mile in an 'out-n-back' or should I say and down and up tour. There are some interesting aspects to the cave, including how it was discovered and the plethora of dinosaur and other animal fossils that have been recovered. About 3/4 way through the cave several actual bones are displayed. Our guide was Mindy. She has been there for 4 years and was very knowledgeable about the cave. For those with more time or who are adventurous, there is a 'flashlight' tour held a few times during the day as well as a 'wild caving' tour. The latter is serious caving and only on the weekends and lasts approximately 4 hours.
Who doesn't like caves and who knew they were so close to Austin! As someone who loves the Carlsbad Caverns these are a great experience on a smaller scale. All around an excellent time.
Our tour guide Jackson was amazing!! The caverns were beautiful and we learned so much. I'd highly recommend trying this place out.
We took the adventure tour today to do something special on Valentine's Day. It was so very busy! Our tour guide was Tom and he was so informative and fun and kind. He had sweet little stories for all the children. He was very knowledgeable. I learned that he has been going to that cave his entire life, he even took his dates there and he's probably a grandpa now. I thoroughly enjoyed myself. Our group was probably 25 people. They had a group descending every 20 minutes. It was quite interesting. The cave actually goes underneath the 35 freeway! We paused and listened and it sounded like lightning as the cars passed over the top. There's an old ladder inside where explorers used to climb down into the cave. That same ladder is on the side of the freeway just like a half mile down inside of a black shed. Nobody knows what's there without taking this tour. They have a beautiful gift shop with lots of wonderful things to buy. They take a photo of each party along the tour and to buy that photo is only $13! They have three different tours to choose from. The adventure tour was one hour. Then they have a 90 minute tour and a 3 1/2 hour tour. The one hour tour that we took was 1 mile long. The terrain is up and down and sometimes slippery so wear your good walking shoes with tread. When you get down to the very bottom, it's pretty warm so don't overdress. Layer with a hoodie that you can tie around your waist. This is not a place for anyone who can't walk a mile on varied terrain--No wheelchairs no strollers, nothing like that. I look forward to going back and taking the longer tour. Every employee that I spoke to was so very kind and helpful. I really like this place. I highly recommend you visit!
Inner Space Cavern is a cool place to visit! We chose the base price/tour option. The whole tour took about 50 minutes to complete. Our tour guide was funny and very knowledgeable. She had some cool facts and tried to be engaging with the large group of about 25 of us. Cons: Felt like the tickets were pretty pricey for the base ticket option (around $24 dollars per adult). The gift shop had a lot of Knick knacks and things geared towards mostly children. Everything seemed to be pretty pricey.
We had a blast at the inner space cavern on the adventure tour. The tour guide was a retired high school teacher and tons of fun. They offer two other tours the hidden passages tour which is a little more challenging and the rooms are not light, so you are given a flashlight for the tour and then there the wild cave tour that's 3-4 hours long and very difficult, so much that your instructed to wear old clothes and theres a wash station where you can clean up before you leave because there's lots of crawling and climbing and you get very dirty. They say the wild cave tour is not for everyone. The tour was about an hour and 15 minutes long. It was lots of fun and I would love to go back and try the hidden passages tour!
Inner Space Cavern was so cool! This cave system was discovered in 1963 when they were building Interstate 75. We did the "easiest" Adventure tour ($24.95 each) which is suitable for anyone over 3 years old, but they have more challenging options available as well. Our tour guide Jordan was phenomenal! Highly recommend this gem!
Tristan was fantastic! He was extremely well knowledgeable on his facts and hilarious. Overall great experience!

We really enjoyed the adventure tour. There weren't any corny jokes. The tour guide was very knowledgeable and polite, even though visitors were not nice to her. We have been to several caves over the years, and this one was worth seeing too. Our favorite part was seeing the bats in the cave. Very cool to see them so up close! We didn't think the ticket prices were bad at all. We got the military discount. read more

We've now been here twice & cannot recommend this place enough!! First time we all came as a family group with a wide age range. Kids loved it, my parents loved it & believe it or not, my teenager even loved it! Michelle was our guide & we definitely hit the jackpot with her as our leader-great information, and a great sense of humor. Our favorite part was her flashlight story. My son came back months later with his friends and did the wild cave tour. They talked about it the whole way back.. and said it was far better than they expected. Take a break from the hustle & bustle, the traffic, social media, and video games & explore the caverns. You will not be disappointed!! read more

Found this place on a whim and went in to purchase our tickets. Had no problems, everyone was nice and the process was smooth! We did the adventure tour with guide Nick. Nick was great! We loved his humor but that he was also knowledgeable about the cave, what's in it, and he seemed to like his job which is always nice. The cave was really cool, the first I'd ever been in and really enjoyed it! We also got to see an extremely rare millipede or centipede, not sure which it was, but Nick pointed it out and was even excited himself as they're very rare. Definitely recommend this place. read more

Absolutely wonderful tour through the caves. Very reasonably priced. Perfectly paced, very knowledgeable and friendly guide, interesting factoids along the way, and well kept trails. Nice easy stroll through the cave, 0.5 miles in and 0.5 miles out. I've done quite a few caves like this, this one is in my top favorites list! If you have an hour of free time while in the Austin area, I highly recommend coming here! read more

If you're visiting Austin, this site is definitely worth the 20 minute drive out of the city. I've only ever visited caverns in Europe so I was really interested to experience something like this in the US and this did not disappoint. We came in here on a chilly December afternoon around 4:30pm (the last tour they offer is around this time, but call in advance to find out more about late afternoon hours of operation). Our tour was small but this was good because we had a front-row seat type of experience with our guide. He explained how the caverns were discovered and how they form. We had multiple photo opportunities and our guide even took photos for us (you have to pay to buy these later though). A very cool thing about our tour - our guide shut off all the lights at one point so we were able to see how dark and quiet it really gets when you are that far underground. If you are lucky, you'll see some bats flying around as well. Just be sure not to touch any of the formations. The oil from your skin will cause them to stop forming. read more
Our guild was great. She kept our large group together and everyone was able to hear her well. It is very neat and there is a lot to learn. I never knew there was once camels in Texas. It is very hot and humid down there. read more
Ok I'll start by saying that I don't really like cave tours...I'm a bit claustrophobic. We did however go on a cave tour in Belize that was amazing. We actually rode inner tubes through the river inside of it. I know that was a once in a lifetime experience but it's now difficult for me not to compare. We went to this cave tour for my 7 year old and he enjoyed it. The tour guide was fun to listen to and the walk was a little slippery but not too hard. I felt like we really didn't walk that much, more listening to stories and looking at the rock formations inside. The tour was informational. I found it interesting that Pre historic animals fell in the sink hole and their bones were preserved. When I35 was being built, the workers discovered it. That was my favorite part. The tour guide mentioned 2 other tours that are more adventurous. If you have young kids or wide age range in your group, they might enjoy this easy going simple tour. No wheel chairs though and the path can be a little slick and uneven. Overall a nice activity. read more

By far, the best experience of my trip. The staff was highly entertaining. I came solo during a business trip and I certainly want to come back with my kids. There is spectacular beauty in these caves and I love the fact that the temperature maintains a naturally comfortable temperature throughout. read more

Let's Rock! It's Hammertime!! If you're in Austin this place is a MUST see! Ranked top #5 out of all caves in Texas! Rachel our tour guide extraordinaire was the Best! We were in the caves for over an hour exploring different minerals - and got so many "cave kisses" water droplets! It was such a cool and different experience in Texas! This place is perfect for young and old children alike- and families, school groups etc. You can even plan your wedding here! It's truly a hidden gem! You can also go for a Zipling ride for an extra $10 with your ticket and there is a special now where you can go on twice for the one price! They have so many fun gifts in the gift shop where you can break your own geode! We absolutely loved the staff's kindness and enthusiasm and the atmosphere was so cool! Perfect place to see the lil nuggets (Bats!) in the caves too! You will not regret it! The Inner Space Cavern should be your next stop for adventure! read more
I've come here numerous times as a kid and even as an adult this place is still awesome. Brought my kid with me and he thought it was great too. They take your picture at the beginning and if you buy it's only $12. They have a gift shop as well. Our tour guide was great. If you look online they usually have a coupon for $1 off. read more

I really needed an activity with my kids and took full caution from mask to hand sanitizer and prepped them not to touch anything once we got there - we had about 15 people total and even though it says it will take over an hour it felt like less then 30 mins, this is coming from someone that's active. - our tour was fun and we took many stops as there are many interesting things to learn my kids are 10-13 so they were def interested to learn. They also have something for kids over 13 which is like a four hour tour which sounded even more fun hopefully one day tho - overall it is def worth it considering living in round rock this was really fun even for an adult. I'd recommend wearing nice sneakers some areas are a lil slippery. They have a cute shop where they sell small things like jewelry, clothing, to kids stuff. My kids had a blast and our tour guide was very informative with everything - I will post a few pics not to much as it takes away from not visiting the place but def a must visit read more
This cavern system was discovered by a core drilling team in 1963 and opened to the public for tours in 1966. Whatever your adventure level, they have a tour for you. Their base tour is an easy walking tour through the caverns with a guide. Their other tours are guided as well and some even require cave-dwellers to wear headlamps and crawl on their hands and knees. Don't worry about weather when visiting - the caves stay a constant 72 degrees tear round, but it feels like 80 degrees because of the 98% humidity. Our tour guide Emily was great! read more
Really cool place. We're visiting from out of town and we were looking for something fun to do in the Austin area. I've been to caves that were in the mountains, but these caverns were deep under ground. When you pull into the parking lot there is a building, but you're wondering where are the caves. You start the journey down a a steep sloped path going into the Earth. Very quickly it gets dark inside, but they have running electricity down there. If you remember from any science classes, stalactites hang from the top of the cave and stalagmites are from the ground. You'll see a lot of those types of formations along with some natural running water. Amazing views and you can take some pictures down there. We did see a bat as well. read more

This Spring Break, after a 3 hour road trip to Austin...me and my family decided that we should make one last stop outside of Austin to make this trip memorable. I searched up the "best attractions near me" and the one of the few attractions that caught my eye was Inner Cavern mainly because of its highly rave reviews. On our trip back to Fort Worth from Austin, we stopped by the caverns to purchase our tickets and experience our Adventure Tour (which is 1 of 3 tours available). The Adventure Tour was the only one fit for my 6 year old, but my 14 year old and I went along with her to be the judges of this tour. My adult ticket was 21.99 and my kids were each 15.99., which seems a tad overpriced if you ask me...and after the tour was over it ended up lackluster. Our tour guide had no personality and little inflection in their voice which made it seemed they were reading off a script or uninterested. The sights were obviously interesting but what took away from it was when our tour guide every 5-10 minutes during our hour tour asked *our* group to move to the side--interrupting our tour. Both going into the cave and out, it was our tour group who had to move to get out of th way even though we paid just as much money as the other group which kind of ruined the experience as a whole. Good place for photos, cool gift shop, straightforward tour,, but the 1 hour Adventure Tour is not worth the price...maybe try the other 2 tours. But if you either want to enjoy caverns with your little ones or want a leisure walk through them, go the distance to find better priced cavern tours! 3/5 stars read more

A wonderful place to see in Austin! The main tour takes about an hour and isn't difficult but there is another tour that requires closed toed shoes so keep that in mind. Also, I thought the cave was going to be a cool temperature but it's very warm. read more

After passing this place countless times on I-35, seeing the billboard and thinking it was more kitsch than substance, I finally decided to check it out and wow, it was nothing like I expected! This place was such a pleasant surprise! I have to say going in, I was expecting the dated, hokey, kitsch that one might expect from a commercial cave (and I have visited my fair share) so I had been putting off visiting, even though I used to live relatively close. When I saw their 50% off Facebook promo, I figured $10 was a safe bet...and wow did I get 3x my money's worth! First off, I liked that it was relatively uncrowded and an easy on/off to I-35. Secondly, the staff is just so pleasant, as in they act like they actually want to be there. Thirdly....they have a zebra!?!? Zoe, the zebra was very lively when I paid her a visit, and though there are signs that say "do not feed/pet the animals" (and righty so cuz she bites!), one of the groundskeepers was feeding her and let me give her some niblets after she calmed down, which I have to say was an amazing way to start my Inner Space experience! The tour itself was fantastic and that was mostly due to our fantastic and exceptionally knowledgeable tour guide (and resident archaeologist) Katherine! I have been on more cave tours that you can shake cave bacon at and she somehow managed to enlighten me with a knowledge nugget or two! And, per the usual commercial cave tour, you get to experience total darkness (which even as many times as I have experienced, never gets old as it is truly something incredible with the only other natural way to experience it is the deep ocean). The cave is just beautiful! The formations awe-inspiring and well maintained/protected and the adorable bats were literally just above our heads! The different chambers were all just gorgeous, but my hands-down favorite wass the Moon Lake! An absolutely wonderful way to spend an hour and 15mins and one of Texas' prettiest show caves with the added benefit of being within a relatively short drive from Austin! read more
I highly recommend visiting these caves. They are amazing !!! Our tour guide Britney was absolutely adorable and also did a wonderful job educating us about the fascinating cavern. If it's at all possible to request her tour I definitely would take her tour and if you notice a baby in your group I would request to take the next tour . A large family had a baby with them and the kid screamed 45 % of the tour . That really sucked . It was super inconsiderate of those parents to bring a baby in caves ! Lol I do not recommend this tour for elderly people or if you have bad knees . You have to walk down a steep hill and back up it to get out . Also it's very wet and dark so you can easily slip . read more

I can't say that I'm a fan of caves. Caves are dark and dank and have lots of creepy things. But, what I didn't know is that caves can also be hot, and humid. Uh, huh. The last time I expelled that much sweat during a tour I was in the Butteryfly House in St. Louis. At least there I still got to see the light of day. Here, well, it wasn't pleasant for me to be in this cave sweating my arse off in close quarters and in close proximity to strangers who were also sweating their arse off. But, little things in the cave made it fun... It would be even more fun if they reduced the entrance fee. 1. The tour guide. She was either having a bad day or she just graduated from the school of How to Speak Like Ben Stein. To top it off, she was Nasty McNasty. This made it much more fun for me as my cohorts were trying to figure out how to ask her why she was in such a foul mood, when it came time for her to ask us, "Are there any questions?" 2. There were some cool rocks. I mean, they were fraggle rock cool. My favorite one was the one that looked like crystal but felt like flesh. And apparently is a live rock that dies everytime you touch it. They had a specific section marked off just so we could touch it. Thus, only torturing one rock instead of all the rocks. 3. The fake bat. OK, we all know what live animals look like and sure, we know that they live in caves. They claim midget bats live in the cave. I do believe them without actually having to see one. I mean, people make a lot of noise and last I heard, bats don't like light too much. But, these people put a fake midget bat up on the ceiling of the first part of the cave. I honestly couldn't contain myself. Laughter ensued when our tour guide was unsurprisingly "shocked" to show us the bat. Best.Fake.Bat.Ever. 4. The ride back up to the surface. This had to have been the best part for me because the last area of the cave that we visited was the most humid one and I was pretty much DRENCHED in sweat. The ride back up to the surface was refreshing. All in all...it was an interesting tour. If you like rocks, c'mon down. If you want to be entertained by tour guides who clearly hate their job, c'mon down. If you hate caves, hate dark, hate dank and humid...best stay up in the surface. Perhaps find a place to grab an ice cold Shiner Bock and wait for the nerds to come up to the surface. read more

My boyfriend and I visited Inner Space for the first time yesterday! For years I've driven by on the way to Austin and saw the sign, wanted to stop, but never could. This time I'm glad we made time for it! We went on 2 tours, the first being the Sister Caves Tour. We LOVED the Sister Caves Tour. It is a walking tour of the land where you learn about the family who still owns the acreage, the native peoples who populated the land years and years and years before Texas became "Texas," the geology of the area, and so many other interesting tidbits. You also go into a "sister cave" that is not on the regular tour. We found this incredibly enjoyable, informative, and well worth our time and money. Our tour guides were Kathryn and Amber and we are grateful they were so passionate about the site, its history, and about archeology and geology. Cannot recommend this tour and these gals enough. We also went on the Adventure Tour which is their usual cave tour where you are taken into the depths of the earth-- a nice respite from the summer heat-- to see beautiful rock formations. Another tour well worth your time. This tour is more commercialized and for the masses, but you'll certainly enjoy it. I suggest going on the 10:30am Sister Cave Tour (bring bug spray and sunscreen and maybe a hat and sunglasses) and cap off your experience with the Adventure Tour. Wear closed-toed shoes that grip well for both tours-- not flippy-floppies. Enjoy!! read more

My buddies and I came to Inner Space Cavern for a bachelor's party. We decided to spend half the day here doing the Wild Cave tour for $100 per person. This tour is for those looking for a lot more adventure than the regular tours they have there. You have to be able to crawl, climb and hoist yourself through small spaces. Descriptions were spot on and we had an adventure of a life time. Crawling through extremely tight places and getting ourself muddied up definitely put an exclamation to our bachelor party weekend. Our tour guides were Lane, Kate and Dean. For a party of just 5, three tour guides may seem excessive, but these three ensured our safety and made sure we got the most adventure for our time with them. The Wild Cave Tour was 4 hours long and these three took us through winding mazes, very tight spaces and incredible challenges. If you decide to do this tour, get ready to suffer some scrapes, bruises and torn clothes. I ended up throwing away my shoes, shirt and jeans since they were so badly covered in mud. Oh make sure you stop by the "Dragon's Mouth" and drink the natural water that has pooled on the cave floor. At the end of our tour, they provided us with refreshments, memorabilia and a place shower. This is definitely a place to have a great adventure. Highly recommend! read more

There were lots of things to see. It was very beautiful it's quite a bit of a tour a lot of walking, took a bit over a hour. We felt as though we got our money out of it even though it was very expensive. Our cave guide was Garrett. He was kind of quiet not 2 and too enthusiastic we could've had a worse guide but we could have definitely had a better guide Overall we all still enjoyed our time and the beauty of the cave read more

Why has it taken me years to come here? If you haven't been here, why not?!? It's a great spot to take out-of-towners, kids, adults, grandparents (if they are mobile). It's about $20 a person for a 1-hour-ish guided tour. Our tour guide was informative and an absolute delight. I brought my family and they thoroughly enjoyed it. It is quite magical once you're underground and looking at how awesome our earth is. Bring some comfortable shoes and enjoy all this cavern has to offer! read more

Do NOT miss this place on your visit to Austin. The cave is breathtaking, and our tour guide was lively and entertaining. FYI: The Adventure Tour involves a decent amount of walking in the cave, both uphill and downhill, on ground that is wet (due to the moisture in the cave--eg., the moisture that enables all the glory that is the cave!), with some small mud puddles in some spots. Leave your Louboutins at home and wear shoes with good traction that can survive a small splatter of muddy water. Bottom line: Even if you've been to other caves, as I have, I think it's well worth the visit. Super fun, and great for families with kids as well as people of all ages. read more
I feel comfortable keeping this review short and sweet (pictures are really all what it's about). Awesome experience for entire family, affordable and the tour guides are knowledgeable and at the least try to be funny. My 13 year old sis really enjoyed this trip and it kinda felt like we stepped into a different world momentarily. My whole family really enjoyed this experience! Definitely a hidden gem for people in Austin, TX. I went to UT for 4 years and didn't know it existed. I would recommend this place to someone of any age that can walk a mile or two easily. Thanks for the cool experience! Tip: call ahead to see the different tour times if there's a specific type of one you want to go to. They range between .5 mile to several miles. read more

Is it cold?
We went during the hottest part of summer and inside the caverns was about 70-72 degrees. Everyone was in short sleeves and either shorts of jeans, it was comfortable and not cold. I can't say how it'll be during a cooler part of the year though.
Is it a good idea to bring an older person (84 yrs)? What is the distance that you're walking over the course of the 1hr 15min tour?
No it's not. It's a pretty tough uphill walk after going all the way down into the cavern
What's a good time to go?
School is out so you won't have to worry about large school groups. Going on a hot afternoon is nice as it is a constant temperature cavern. Otherwise, it makes no difference.
