I had been interested about this place for awhile, but was skeptical about it because he outside looks so dead and boring... But then my brother-in-law came to town and my wife and I wanted to take him all around. We found ourselves at the Inner Space Cavern, and boy was it worth it! ----- I'd highly recommend going during the week around when they open because you basically get the whole cave to yourself (your small group, plus the tour guide). On our tour we had a couple and that was it. We headed down into the cavern and I was incredibly blown away at what was underground! I truly wish I could remember our tour guide's name... he is a older gentleman--he was definitely a highlight of the tour. Very funny, personable, and knowledgeable. ----- If you're on the fence about doing the tour, just do it! We did the standard tour and we already want to go back and do the other, more rigorous tours. It's a little pricey, but definitely worth doing! read more

Good time. It was a nice date for my husband and I. We plan on returning with family.

I came here with a group of hike leaders from the Friends of Balcones Canyonlands National Wildlife Refuge and we had an amazing time! Our tour guide Brandon gave us a fun and insightful tour. The cave far exceeded my expectations, and I left with a lot of new knowledge that I will be able to share. I will definitely be back with other friends to visit. The tour is great for people who like to learn about nature and enjoy activities with some walking involved. Our group is comprised of many people who enjoy nature and the outdoors, and all of us were very impressed with our experience and the cave! read more

3.5 This place is fun but your mileage may vary depending on your tour group. The caverns themselves are amazing and a good place for photos. However, if you were stuck with a tour group that asked bizarre nonsensical questions about bats eating ice cream or repeatedly asking about dinosaur bones you won't get to hear all the cool factoids. We missed out on one room because one family was super slow because they didn't like water on the floor. This is a living cave so there are puddles, mud, bat droppings and other dirt on the floor so wear appropriate shoes. It can be slippery so hold onto the railing, there are also floor mats in steep places however. You can't touch the rocks. It's a felony. There is only one place you can, your tour guide will tell you. Be forewarned, they will, at certain points, turn out the lights. I could tell our guide questioned her life choices...otherwise it was fine. I might go again, when it's cooler and emptier. If you're hardcore you can pay extra to do an extended tour where you can crawl though tiny caverns. read more

One of the more interesting and easily accessible cave system near Austin. The Adventure Tour is very popular, about an hour and a half for $20. They also will take a family photo and try to sell it to you for $12 at the end. Most people just take their own photos with a camera phone. Keep in mind the caves are super humid (~98%) and always a nice cool room temperature year round. The path is stone and almost always wet so wear good shoes. They turn the lights out at one point so you can experience total darkness, which is only possible in deep caves. If you have kiddos deathly afraid of the dark you might want to wait until they're older. read more

The Cavern is a must see. You will not be disappointed. Additionally, this cavern is the most accessible cavern I have visited due to it being a ramp in and out versus 50+ stairs as in most other caverns. Miles (the tour guide) was awesome. He had a lot of humor and was very knowledgeable when asked any questions. My disappointment was in the misinformation with the front desk. We arrived at 2:50pm and we wanted to do the cavern tour, and the zip line. The tour was at 3:10 which was perfect timing. The lady at the front said we can do the zip line before the tour, but we wanted to eat so I asked if we can do the zip line after the tour and she said with assurance that we definitely can. We proceeded in going on the tour which finished around 4 and went to the zip line that appeared to be closed. We went to the front desk again and stated we wanted to do the zip line where the lady said that it closes at 4. I let her know that someone else had let us know that we can do it after our tour. The lady apologized and said she doesn't know why her coworker would say that since the zip line closes at 4. She provided a refund, but it didn't change the fact that we didn't get the experience. read more

I took the Hidden Passage tour. I would say I completely enjoyed my experience, if the other groups were constantly overlapping the tours. Other than the unfortunate and consistent interruptions...the guide was knowledgeable and appeased those in the group that wanted to mosey along. read more

I took my two small children 2 and 4 naively thinking it wasn't a guided tour. Once there I realized it was indeed guided and almost an hour long. I wasn't sure how they would do but I had come too far to turn back to South Austin now. The kids were highly entertained and when they became a bit restless the tour guide took turns making them his helper! Without this amazing man/ tour guide my youngest would have surely thrown himself over the rails face first in bat poo for entertainment. I highly recommend a visit even if you have little ones! read more

Leroy was the best tour guide. Amazing dad jokes that made the visit fun. So glad we stopped here! Never been in a cave and this was incredible. Dinosaur bones and everything. Kids loved it. Awesome place. read more

This place was amazing. We had so much fun here it was great seeing everything under ground and learning about the formation. I also enjoyed the zebras that were very friendly! read more

Very cool place. You walk a bit but not fast at all and the cavern feels like it has site conditioning. Great for the summer months.

Our guide was very informative and funny. There is a hand rail to help. The lighting is lovely. Got a lot of great photos.

My little girl said it was boring but my teenager loved it. My 64 year old mother said it was better than the caves she visited in VA. The tour guide was sweet any funny. It was overall an educational and also a great experience for the entire family (even my little girl ) What to wear: When we went it was like in the 40's outside. We kept the jackets/coats on at the beginning but further inside the cave we had to start taking off layers. Can't imagine what it would be like inside when it starts getting hotter outside. Wait Time: When we got there, they had just opened. We purchased tickets for the 1st tour and minutes later we were on our way. All throughout our walk-through we would see new groups embarking on their own journey, treading the same path that we took. Anxiety Meter: I thought it would be claustrophobic in there or I was fearing the day that we go would be the day the cave literally caves in. But we made it out alive!!!There were lights throughout the tour. Not enclosed at all. Bats: Yes we saw one hanging by herself. She was adorable. How do I know it was a girl? B/c our guide said so, duh!!! Gift Shop/Concession Stand: If the cave isn't your thing, you can hang out here. Try the chocolate rocks. So yum. Bathrooms: Clean! Recommendation: Go!! read more

Place was really cool to see with my family. Staff was extra friendly. Our tour guide Payton was super friendly and funny.

This cave is pretty cool. I did the standard tour and found it to be very enlightening. Our tour guide was very knowledgeable about the historical aspects of the cave, did a great job cracking some jokes along the way, pointed out baby bats when we saw them , and really seemed to enjoy what he does. The tour itself is a mile walk (1/2mi down and 1/2mi back) that you complete in about 30mins. The hardest part was coming back out of the cave...hello there glutes! read more

This place was very cool. For all ages too. Our tour was entertaining. I only wish I knew that it gets really hot down there! They mention leaving coats early on but being a newbie on a cold winter day I kept on going fully dressed. Towards the end I was dying. Had to carry my sweatshirt and jacket. Still had a great time though. I would do it again. read more

I have been to Carlsbad, and this neat little cavern is worth the time. It has some good history, and if your guide is entertaining and informative you can leave with some new knowledge about the area. The price of entry is a bit high, but it is not a state park so I can see why Inner Space would need the extra funding. It is fun to go to at least once, and I have taken mykids several times over the years. read more

We had a blast learning about the caverns. The staff were all friendly and informative. Don't wear flip flops! It can be pretty wet down there at times. read more

It was humid as can be when we went, took a 16 month old and 5 year old with us. NOT a good idea especially being you can't touch anything and they want to go everywhere but stay on the path. I remember this place as a 1st grader on a field trip and loved it. The ice cream hit the spot afterwards- I enjoyed it but it was rather stressful with the kids :/ read more

It's a nice place to visit, they have 3 different tours that you can take. Starting at about $20 a person and it goes up from there. The tour guide that we had for the 1st tour with the largest cave rooms had a, I'm over this job attitude, wasn't very excited to making the experience all that it can be. It definitely made the tour not worth taking. Hopefully you do not get this going tour guide and have a better experience. read more

My husband and I decided to go on one of the cave tours. The cave was amazing! We learned alot from the tour guide. This is definately a go-to when visiting austin! We saw a few small bats and purchased souvenirs and pictures. read more

It's a cave ,and it's undergroung just like the other caves on the Balconies Fault Line. The plus side it has some super cute examples of those adorable chicken nugget bats, plus it has some interesting formations for an avid rock hound. You can take a tour off beaten track for a premium. However, Longhorns Caverns is more interesting from a historical perspective . Natural Bridge Caverns have more tourist crap like zip lines and "mining". From a geological standpoint all central TX caves are pretty much the same. This one is good example without having to go out if the way. read more

I've visited many caves in both the US and abroad, and I've always been on the main tours, craning my head around the corners, looking past the "Do Not Enter" ropes and wondering "What would it be like to go down THAT passageway? Could I deal with going feet first down a black hole lined with sharp rocks?" I got the answer this past weekend during my Inner Space Cavern Wild Cave Tour. This is NOT, I repeat NOT a review of the regular, take-the-kids-and-follow-the-walkway tour. MY trip was the extra-extra special, helmet, kneepads, pant-tearing and claustrophobia battling tour through the underbelly of the cavern, accompanied by a few friends, a few strangers, and the brother-sister guide team of Brennen and Dani. The operators of the cave provide a list of what to wear/bring, and they provide helmets, knee and elbow pads, and head lamps. After a brief orientation, we headed into the pit, past not one but TWO "Do Not Enter" signs, and got our "Before" pictures taken. In looking at those pictures I'm reminded of my 1988 HS Senior Pictures, "I look so...clean...". What followed was 3+ hours of driving ourselves through an incredible Inner Landscape on our hands and knees, knees and elbows, stomachs, backs, and fingertips while the guides explained what we were seeing and experiencing. Dani and Brennen were fantastic-they were great teachers of technique ("OK, now twist around that rock and PULL!") as well as good story tellers. The family dynamic between them was an added element that we appreciated-at one point Brennen threatened to teach Dani's 2-year old son "adult" words if she kept talking about how hungry she was. We had a fun group, and we asked as many questions about the different experiences the guides have had as we asked about the cave formations we were seeing. Funny stories about the kind of questions people ask when they call the info line ("Have y'all changed location at all?") and what people ask on the tours ("How long did this place take y'all to build?") seemed to top the list. While navigating the route, there were plenty of tight spots that made me grateful that I'm only mildly claustrophobic. A particular crevice where we had to crawl, twist around and then leverage ourselves up to a higher passage was very challenging, and on the last 40-foot crawl on our bellies, the ceiling and the floor seemed to be no farther apart than the EXACT dimensions of my backside. Those were about my limit, but they were all ultimately navigable. One of my companions mentioned that he never felt any kind of concern at all, so I think 99.99% of visitors would find the experience doable. There are plenty of rest stops, incuding a meditation-inducing Nap Room with all the lights off and comfy, crunchy rock to lie down on for 20 or so minutes. And it is incredibly worth it to experience the Mud Room, the Dragon's Mouth, The Canyon, and numerous other caverns that would be impossible to sample without braving the tight passages to get to them. There was only one real concern about the trip-There is NO way to...ahem...use the facilities... while in the caves. If you are on the tour, make sure you take the Guides' advice and hit the restroom a last time before leaving the check-in/gift store area. And make sure you've eaten OK, there's no food allowed on the tour, although the Guides do carry a few water bottles to share. It's a very physically demanding trip, and I was definitely glad I had packed PowerBar to devour as soon as we made it out of the caves and back to our stuff, stored in the office for the duration of our adventure. A couple of notes- This may not be a good trip for people of strong religious beliefs about how and when the earth was formed. Frankly, I want my guides focused on telling me where the footholds are versus defending the statement "It takes thousands and thousands of years for this little pillar to form, imagine how long to make that big one over there." While there were no issues within our group, apparently that kind of thing has come up occasionally in the past. Don't wear ANYTHING that you'll be unhappy having ripped, torn, COVERED in mud and clay, or otherwise damaged. The sharp and pokey rocks are...well...sharp and pokey. I had a cargo-pocket torn half-off, and the olive green T-Shirt I started with was a lovely muddy khaki by the end of the day. Finally, I think that any reasonably in-shape person should be able to do this tour with very little problem. The guides are experts at showing different ways to get through passages and up/down holes. We even had some discussion about upper vs. lower body strength and which method would be best for men (in general) vs. women (in general). Everybody made it out ok. The price tag may seem a little steep at the outset, but now, having experienced it, it seems like a great price for an experience that was challenging and fun. Bottom Line-GO FOR IT!! read more

The first time I visited the cavern, it was the first time I had ever been on a cave tour. I was fascinated. It was so much bigger than I had expected. And the fact that no one knew about it for 10,000 years, is pretty crazy. The tour guides are great, they are young, fun and humorous. Its so interesting to learn about the rock formations, and see rocks that are millions of years old. So, there are a few different tours available. The adventure tour is beginner/all ages (under 3 are free), then there is the Hidden Passenger tour which is intermediary/ages 7 & up, and the Wild Cave tour for advanced/13 years & up, this tour will take up to 4 hours. Since my first trip, I have returned numerous times to bring friends and out of town visitors. I'd highly recommend checking this place out, especially for those who enjoy geology and natural history. Tips: Dress in layers, it is pretty chilly down there, but also humid. Per their website, the caves maintain a 72 degree temperate year round. Be advised you will likely see bats. I'd suggest wearing comfortable footwear. Oh, and steer clear of the petrified mountain of guano! read more

The folks who run the Inner Space Cavern have taken a very interesting and unique natural wonder and turned it into a cheesy tourist trap. The cave itself is beautiful and interesting but in order to see it you have to go through a gift store filled with cheap garbage, listen to a tour guide whose schtick is geared for 8 year olds, and have your photo taken at the start of the tour. When the tour guide was sharing actual facts I enjoyed the tour but unfortunately about 45 minutes of the hour spent in the cave was spent listening to ridiculous comments/bad jokes and/or waiting around for other tour members to catch up. Having said all that the cave is home to the 2nd smallest species of bat in the U.S. and you can get very up close and personal with the cute bats if that appeals to you. Glad I went one time but I wouldn't go again. Not even if someone paid me to. read more

I normally don't leave reviews but I wanted to take the time to give Rachel our tour guide the biggest shout out! Her tour was amazing! She was informative, funny, and very patient with children. I have a hyper active 6 year old boy who doesn't do well paying attention to most things but Rachel held his attention the entire tour and he learned so much! He now says he wants to be a "cave explorer". If you ever come here for a tour make sure you get on one of her tours especially if you have little ones! Thank you again for the wonderful experience read more

I've been to many caverns in the USA and Puerto Rico. While this was not the best, it was very interesting and our guide, Jana, was knowledgable & friendly. The walk is pretty easy & there are a few lil chicken-nugget sized bats living in there so you can see them here and there. Good for an afternoon trip, takes about 1.5 hours to do the 3/4 mi. tour. Apparently they call it Inner Space Caverns because it was discovered right around when moon exploration was going on. Thus "outer space" and "inner space". Kids are welcome on the tours, but some shouldn't go... Parents, you know who you are and the rest of us don't think your bratty kid is cute. read more

If I could only review the cavern separately from the tour because the two would get very different ratings. The cavern itself is very pretty and extremely well-kept. I've toured lots of other caves and while others may be more extensive I felt like this one let you get closer to the actual formations than many. Plus, I thought the strategically placed colored lights added to the experience. Four stars for the cave! The tour gets 1. How about a bit more time talking about the science and less time spent on the cheesy names for the formations? I would give alot to have back the 5 minutes spent hearing the "names" of a dozen formations in a cavern. Yes, I can tell it looks like a whale without anyone pointing that out. The worst part was that the second you get into the cave you're lined up single-file for the "mandatory" picture. I a stupendous time waiting for 10 minutes while each family unit smiled for the camera. Not really. The pictures will be waiting for you, at an additional cost of course, in the gift shopafter the tour. Unfortunately, that kind of start soured the whole time for me. Bottom line: great cave and well taken-care of but the tour needs some serious work. read more

It's amazing to think of how often I drove on I-35 never realizing that a whole other world lay just a few feet beneath me underground. Inner Space was found in the 60's and is privately owned. I had the luxury of visiting on a weekday afternoon and avoided all the crowds and was able to tour the caverns in a small quiet intimate group. As a result, we were able to experience total darkness, hear the sounds of the caves, and experience several of the small native bats that live here fly by us. On the weekdays they only offer the adventure tour for $20 per adult; it leaves every 20-30 minutes and you don't need a reservation. On the weekends you can also experience the new hidden passages tour that takes you through a new area of the cavern on an undeveloped trail with only the light of a flashlight. This tour is only offered a couple times on Saturday/Sunday and you don't need reservations. The cavern is consistently warm and slightly humid making it a great escape for a cold rainy day. On the adventure tour we explored the cavern with our friendly informative guide on a relatively easy developed trail that was well lit. You exit the cavern on the same path that you enter. The cavern is full of breath taking formations located in several different rooms that you journey through along the path. It's hard to put words to this other worldly place. My trip here excited my sense for adventure, my eye for art, and satisfied my nerdy science brain. While not as expansive, immense, or large as Natural Bridge Caverns; this place was still awe inspiring. read more

This was my first visit to any type of 'natural cavern'. I wasn't really sure what to expect, but my partner wanted to go -- so off we went. When you arrive there is ample parking and a nice gift shop to browse while you are waiting for your tour to start. We opted for the 'beginner' tour -- it was a lot of fun. It lasted about an hour and is great for all ages. The only thing to consider is that you need to dress comfortable. There is very little ventilation in the caverns, but the view and commentary from the tour guides are AMAZING. It is well worth the money for you and the kids to give them an idea of how nature works. read more

I've been to only two caves in Austin, so I'm not an expert. I've been to Inner Space and ...another one that I can't remember (and that I didn't like, so no loss there.) But what I saw at Inner Space helped me understand the fascination with spelunking. I took my son and daughter there, and they fell immediately in love with the "panning for gold" attraction--yes, completely silly and arguably a waste of money, but the next tour didn't start for another 45 minutes and the kids needed something to keep them entertained. They loved it. And after all, this particular adventure was all about the kids, so it was all good. Or at least, I thought it was all about the kids. The caves were phenomenal. We were lucky to have a really knowledgeable tour guide who was able to reveal all sorts of fascinating information about the surrounding area as well as the prehistoric animals that used to live in the caves. The enormous pile of petrified bat guano was truly spectacular. (I kid you not. Even if you don't like poop--but who doesn't like poop?--you can't help but be impressed by this.) Impressed and kind of terrified. The tour of Inner Space really illuminates how vastly different the world used to be, and really gets you wondering about what the world could be like in the future. The tour guide explained about the caves being "alive", and explaining how they grow over time. If you're at all interested in caves, take this tour and then watch the episode on caves on Planet Earth. It'll rock your socks. If you do have little ones, be prepared to make sure they keep their hands to themselves. Touching the cave walls is a huge no-no as that ruins the cave's ability to grow. My son especially wanted to break the rules, so I had to put the fear of God into him. If you're looking for something new to do on a weekend, give this a shot. ti's especially nice in the summer, as the caves are considerably cooler than above ground. Happy spelunking! read more

This place is amazing. The tour takes about an hour. When it is winter, the cave is comfortable and warm, and when it is summer, the cave is refreshingly cool. The tour guide gave us tons of information on the history of each room inside. The guide will also let you know if you are allowed to take photos, or touch the rocks. We did the basic tour, where we walked around for an hour. Next time we are going to do one of there wild cave tours so that we could climb, hike, and crawl in the caves. read more

Fun place, a good enough time walking around the caves. No bats except old bat guano, but they have an abundance of cool shaped stalagmites & stalactite. Be sure to call in to see what time is best to visit to avoid the hoards of field trips. They also offer military & AAA discounts. Don't wear sandals unless you want to get muddy feet. read more

This review is for the Wild Adventure tour. Tour price: $100 Tips: $40 (optional, I LOVE my tour guides) Broken Camera: $90 (I will explain) BEST TOUR EVER: PRICELESS! This tour is physically demanding, and you might have to be in certain size, I'm waist 38, and I couldn't squeeze through one of the space, so I do see anyone bigger than me might have a problem. We spend about 3 full hours crawling on our knees, playing with mud, seeing things that most tourist doesn't get to see. It was just awesome. and I was exhausted in the end. you will want to wear long pants, long sleeve shirt, tennis shoes or hiking boots with good traction and ankle support and a bandanna. Make sure you wear something you don't mind throwing away if the dirt doesn't come off. Oh and bandanna is important if you have short hair and sweat easily like me, it helps stabilize the helmet. If you are lucky, I hope you get Randi and Tayler as your guides, they are awesome, don't be shy to tip them. Another suggestion,bring travel size camera, you can ask the guide to carry it for you (they carry a bag with water), don't put in your pocket because the dirty will get in it and it will destroy the camera (like mine, good thing I was going to upgrade anyways) read more

My Austin friends recommended this place as a must-see but it ended up being a complete waste of time, not to mention waste of gas driving to/from Austin! Based on their recommendation, we went with the beginner "Adventure Tour" which was a completely underwhelming snooze fest. With these sorts of tourist traps, I find that the quality of experience is directly tied to how entertaining the tour guide is... while I still scratch my head at all the 4/5 star reviews, I can see how a better tour guide would have made the experience more enjoyable. read more

This is one of the places my mom took us to during my childhood. It is a very cool and different place to visit. My son is really into "rocks" (geodes, minerals, etc), so this tour was right up his alley. It is a little pricey, but it is a good educational experience for the kids. We did the walking tour. YOU NEED TO WEAR COMFORTABLE SHOES!!! Do not wear flip flops, sandals, etc. The cave floor is very wet and can be slippery. If you cannot walk a mile, I wouldn't do this tour. The entrance is very steep. There are "more adventurous" tours for those who want to climb and crawl through the other veins of the cavern. The "tourist" trap that many mention is there...but with my son being really into rocks and minerals, it was cool. The sluice box where the kids can "mine" for gems was a ton of fun for the kids. HINT: The gem back with sand is only $6. You will get 6-10 rocks/minerals/arrowheads/fossils out of that bag. Not a bad cost when you compare it to the ones inside. My kids had a blast doing this mining..... Again, very touristy, but it was a nice touch for the kids. Also, I don't mind paying a few extra dollars to a place that is preserving a natural treasure. Part of my enjoyment was seeing my kids having the same fun I did when I was a kid. The place has not changed much. read more

This was a really cool experience! I recommend this place especially if you have kids! It's $20 for an adult ticket which is really over priced! But you can find a buy one get one free coupon in the issues on gtownview.com which made it better! :) the temp is around 72 degrees throughout the cave but it does get really humid so you won't need any jackets or layered clothing. read more

This was the first time I had ever been to a cavern for a cave tour. We took the Adventure Tour. I believe our guides name was Brett, and he made the tour even more enjoyable. I made the mistake of wearing sandals.. I would suggest to wear closed toe shoes or sneakers. Inside the cave was amazing.. Some of the formations inside are a million years old! Definitely a sight to see! No reservation required! They have a gift shop and concession area just in case you have a small wait until your tour begins. They have different tours you can take that differ in price and route. The Adventure Tour is kid friendly. They also have a tour called Wild Cave Tour for $100 a per person but based off the Adventure Tour we took, there is no doubt that it would be worth it! I will be making a trip back! Ps. There's no Pokemon in the cavern.. Haha read more

Had a great time at this place. Some spots are really tight to crawl through. They also take your photos and give you prints of them as well on the wild cave tour. The guides we had were billy and Tara. They were very knowledgable and understanding and did not rush anyone in our tour group. Also got to drink some cave water. Prob the best water I have ever drank. Bottom line it's a great experience and a must do for adventurers. read more
