The cave tour was so amazing. It’s important to remember to see this cave you have to follow strict instructions to protect the cavern that is possibly the most beautiful and amazing thing on this planet. The story of how it became is very interesting. Take the tour you will love it as long as you appreciate nature. There is a small botanical garden in front of the center. There is a gift shop and small cafe that serves sandwiches. There is campground there that is quite nice. It’s kept up quite nicely. They have water and electric for your camper, a dump station and bathrooms equipped for handicapped. The bathrooms are kept up but needs updating. The only con I can come up with is that the bathrooms are so very cold I don’t see how anyone could possibly take a shower in such a cold room and the bed thing in the shower is so far away from the shower head that I don’t think it’s usable. Hiking the trails around the cavern was nice. I definitely recommend trip to the Kartchner Caverns.

Excellent cave tour!! Professional presentation given by knowledgeable guide. We arrived a few hours early, bringing our own food to eat at the picnic tables. Very clean with garbage cans nearby and areas to grill using your own propane tanks.

Professional presentation given by knowledgeable guide. We arrived a few hours early, bringing our own food to eat at the picnic tables. Very clean with garbage cans nearby and areas to grill using your own propane tanks. Inside the visitor center there are all kinds of well done exhibits & a theater showing an informative movie about the cave. Nice gift shop, cafe, and clean stocked restrooms. Friendly employees were helpful and you could just tell they love their jobs. Overall, a must see if you are in the area. Best to rsvp tickets well in advance. Hiking & camping available too. You do not want to miss this! I was wholly impressed with the thought that went into the guest experience!!

Beautiful State Park. Well maintained. I went on the Big Room tour, our guide was Rich. He was very knowledgeable, and had a wealth of really goofy jokes and puns. I enjoyed his sarcasm and wit, as I'm English born, and don't hear it very often in the US, so it was an added plus for me on top of his enthusiasm for the caverns and his wealth of knowledge. Very interesting indeed. The cave was prett... Beautiful State Park. Well maintained. I went on the Big Room tour, our guide was Rich. He was very knowledgeable, and had a wealth of really goofy jokes and puns. I enjoyed his sarcasm and wit, as I'm English born, and don't hear it very often in the US, so it was an added plus for me on top of his enthusiasm for the caverns and his wealth of knowledge. Very interesting indeed. The cave was pretty spectacular, and very humid, (99 pct). Thank you Rich. ... Afterwards I visited the cafe, the menu had quite a few choices, better than expected. My coffee was cold though, hence one star missing. Good coffee matters! 😜 I also got to watch a presentation on bats, and even touch a living bat and feel its heartbeat, which is very fast. This isnt an every day thing though, so dont expect it. All in all a beautiful visit, and I managed to spent 5.5 hours here. 👌🙏🙏

Awesome piece of well perverted nature! Awesome tour guides and friendly fun environment! Nothing is allowed in the cave including cell phone, no pictures of the inside except on selected dates. But that how they keep it special for everyone!

One of, if not the best State Park in the system. The cave tours are excellent. The campground is top notch with well spaced sights.

The campground is top notch with well spaced sights. The surrounding area is rich in historical sites, and the Sonoita opportunities for food (The Copper Brothelbrew pub), wine, and distilleries is a great adult day trip. And, the incredible Empire Ranch is also near Sonoita. Wildlife opportunities are abundant both summer and winter. We really enjoy White Water Draw in the winter to see 10's of thousands of Sandhill Cranes. So, its just not the cave and campgrounds - there is a vast area to explore.
