We stopped at Onyx Cave on a total whim during our road trip and so glad we did. This was the perfect little adventure break, especially with kids. I have a 3 and 5 year old and they both LOVED it. It's short, sweet, and just enough "wow" without being overwhelming. The cave itself is really cool, with some tighter crevices that made it feel a little adventurous (my kids thought that was the best part), but nothing too difficult or strenuous. If you're worried about that--don't be. It's super manageable and moves at a good pace. Price-wise, it felt totally worth it for a family stop. They've also got a little gift shop at the end which my kids obviously needed to check out lol. If you're passing through, just stop. It's a fun, easy memory to make and doesn't take up your whole day. Would 100% do it again. read more

Super cute and quick cavern tour off the highway home to Cincinnati Believe it to be family run and owned very knowledgeable about the caves and cave systems and how they came to be found child friendly, but some spots can get very claustrophobic read more

A short boat trip but super cool to experience! Friendly staff and loads of history for cowboys-&-Indians enthusiasts! Easy to book tickets online and adorable gift shop! read more

So to be honest. This is a small mom and pop place. Nothing majestic. Lighting is lacking as well as are all the facilities. However it is $11 and the people were nice and hard working. There were some notable things in the cave but it is not majestic. Small and on the dark side. But I suggest you go. It's great to support things that are not owned by millionaires read more

Cute store. Cool tour. Staff were friendly, and wrapped everything I bought. Love the care they took. The rocks aren't completely over priced like everywhere else. Really happy to have randomly stopped here. 5 stars! read more

I have not visit Onyx Cave for the cave yet only their Rock Shop. Today was my first time in. They have a lot of great options of gems/mineral polished and in their natural form. The couple that were running the shop tonight were really friendly and nice. After viewing the pictures of the cave on here I will have to come back and check it out before I move out of town. I should be back for a tour in the next day or two. I found some beautiful stones I purchased. Btw here is a hint to find some cool fossils. If you search through their barrels of geodes you can find some Geodized Gastropod Fossils. read more

Very cool experience. Lots of formations and the tour guide was informative. Very well lit.

Nice short tour of the cave if you don't want anything to strenuous staff was very friendly

A very small tour. Our tour guide, a paunchy mid-20's young man, was a bit crude and very obnoxious. It was interesting enough but I would hope you get a different tour guide. read more

Onyx Cave is right off the highway, but don't expect a roadside attraction. This is a real cave tour. The stairs are steep and PLENTIFUL. A few passage ways are narrow. The only reason I didn't give the 5 stars is that the entrance to the cave was less than impressive. This tour did not very long, but the cave formations are IMPRESSIVE! It is a great way to stretch your legs during a long road trip. Our sweet tour guide was SO nice! Even the gift shop/rock shop was fun (prices are better here than a few others we visited). read more

Onyx Cave is one of my favorite caves in the Mammoth Cave area. I've been here several times and always leave happy. The beauty of this cave is amazing and it's not too hard of a trip for people of all ages. Missy is wonderful and her knowledge and patience always impress me. I look forward to visiting this cave again!! Plus now I have a super cute bat hat!!! read more

Great experience all around. Stopped in to look at the rocks, but ended up doing the tour. Cave is beautiful and the staff were very friendly. Highly recommend! read more

The tour was educational. My Friends and I were on a small group tour given by the owner. She was full of information on the hows and whens of the cavern. My friends and I did two different caves tours, and Onyx came was the most educational and equally as jaw-dropping as the Crystal Onyx cave. You will get your money's worth. read more

My husband and I were passing through town and decided to stop, very glad we did. We had both been through bigger caves but this one was very unique and our guide, Autumn, made the experience fun as well as interesting. She knew the answer for any question we asked. Highly recommend. read more

We really loved our tour of Onyx Cave with Autumn. She did a great job of explaining everything and answering questions. Very knowledgeable. The cave is well lit and very interesting with lots of different formations to see and some narrow places to navigate which made it more fun for the kids. Would highly recommend an Onyx Cave tour for anyone visiting or passing through. read more

We had Autum as our tour guide , she was funny and knowledgeable. She didn't sound like she memorized it and was repeating it .the cave was beautiful and is very underrated. I wish it was a little bigger tho . Over all great cave! read more

Autumn was our cave tour guide! She was super knowledgeable and showed us some amazing features of the cave we would have missed otherwise. Onyx cave was so much fun to see! There were some tight spaces and some steep stairs but walking through the it was worth it! Super amazing sight to see! Would come back! read more

Onyx caves was such an amazing experience! We stopped here for the little shop for the special rocks. We realized they offered cave tours. The caves were breath taking. The tour was around 30min but the experience was so worth it. This cave does have very tight places so if you are a big bone person, I would not recommend this. Otherwise this cave has about everything you can possibly think of to find it a cave. The young man who gave us the tour was very informative and super relaxed. He answer all the questions and gave us extra time to closely check some parts of the cave. The price was the best part of it. I definitely recommend this place to anyone who is up for adventures and appreciate nature. read more

We were pretty frustrated on spring break that we couldn't get into Mammoth Cave National Park, and there were so many confusing options for other cave tours. Onyx cave is right off of 65, up on a hill, next to a haunted hotel (HAHA Don't waste your money at the haunted hotel). What a perfect cave to tour with our family! I don't know if my 5, 5 & 7 year olds would have made it through the whole 2 miles of Mammoth Cave. Onyx Cave tour was maybe 45 min. The tour guide was so knowledgeable. Honestly we were so defeated on our trip after not being able to get into Mammoth, Diamond Caves being sold out, and being so confused on the different smaller cave options... Onyx cave saved our mood that day, and was such a memorable part of the vacation. read more

I toured Onyx Cave with my parents, and we had a great time! The tour guide was very knowledgeable and enthusiastic about caves, making the experience very enjoyable. We didn't feel rushed at all, and the tour guide allowed us plenty of time to take pictures throughout the tour. The cave was beautiful and unique. Everyone was extremely nice. Will definitely return! read more

Stopped with my family shortly before closing time to check the place out. We weren't expecting to be able to do a cave tour but a gentleman came outside while we were stretching our legs and said he was about to do the last tour of the day if we wanted to join. We did. And we were so happy we did. Our tour guide, Jared (not sure the spelling), was awesome! He was very educated and knew a lot about the cave itself and surrounding geology. But he also was very informative about human nature, genetics, and science in general. He kept my older teen boys interested and engaged. Especially when he talked about the spiders. We visited multiple caves in the area during our visit and this one was our favorite. Jared made the visit awesome for all of us. The gift/rock shop had a good selection at fair prices. There were two main things that stood out to me about this particular shop. First, they sold bags of mixed rough stone. This may not be of interest to many but was an awesome find for my family. We tumble rocks at home and being able to buy a bag or rough rocks allowed us to take them home for tumbling and carry out adventure a little further. We will get to relive our adventure back home with the rocks. The second thing that really stood out was a selection of pendants and chains/cords for making your own necklace. My daughter and I were able to pick out a pendant and chain that we liked and have a custom momento from the visit. The owner seemed very nice as well. The shop was clean and organized too. It was a great experience and I highly recommend it if you're in the area. The cave tour is short and the price is very worth the visit. Amazing views with a variety of formations you can see up close. read more

Amazing Tour! We loved it sooo much and we highly recommend this as place to stop! #goddessandwolf Certified! We would definitely go back!!!

What a great tour! I have mobility issues (bad back which causes more pain in the legs and feet). I still found this tour very enjoyable and educational. Although you still have to navigate narrow stairs, I did not find it overwhelming. Having been raised by a spelunker, I found The tour guide extremely knowledgeable. He knew all about the biodiversity of a cave and enthusiastically explained it in terms anyone could understand. Everyone in my family really enjoyed it! read more

Friendly tour guides. A lot of interesting formations. If you don't like tight spaces probably not for you.

Onyx Cave is maybe a tenth of a mile off I-65, and I am sure thousands of people drive by on the their way to Mammoth without noticing this cave or even giving it consideration. Plus it's right across the road from the dinosaur tourist place, and it would be easy to think this was of the same ilk. But this is the real deal! My two teenage kids and I thoroughly enjoyed this cave experience. After a short wait upstairs in the rock shop (which has some cool stuff at decent prices), our small tour of 6 was led behind the building and through a steel door into the cave. The early part of the tour feels like you are not going deep into the earth, but be patient. Eventually you'll decend about 40 feet down very sturdy steel stairs and find yourself in a truly amazing underworld cave, surrounded by stone flow, stalagtites, stalagmites, cave coral... Everything you hope to see in a cave. There are beautiful spaces, a few tight squeezes (fun not scary), and the whole path is well lit and the pathways are level for the most part. Our tour lasted just under 40 minutes, led by a very friendly and knowledgeable young woman. Perfect amount of time and well worth the $8.95 admission. It's a bargain to see such a natural wonder. Only caution, there are a lot of stairs, they are all excellent with 100% solid treads and railings (and well-lit), but for older folks with knee problems or balance problems on stairs, this would not be a good choice. For everyone else though this a solid 5 stars. We loved it. read more

Wow, best cave open for tours in the area! Small but well worth the time!!! Wet inside with lots of cave coral, cave bacon, and Hugh flow stone and drapery. Up close as personal tours given by Missy, whose is a volunteer caver of 100's of caves in the area. She is so knowledgeable and takes her time answering questions. I have caved a lot, but this is he first cave I have been able to be so clean so to the formations and get awesome pictures! I highly recommend this cave tour. read more
