Bring Bottled Water 💧

Cave water is not recommended for drinking or cooking due to sediment. Reddit

Check Campsite Levelness 🏕️

Some RV sites are very unlevel; check descriptions or call ahead. Reddit

Sadly, no phones are allowed inside Kartchner Caverns. So you’ll have to go and see it for yourself! It’s UNBELIEVABLE! There’s another cave that closes during the summer because the bats live there, so we’re going back in October to see that! It’s completely insane. How they discovered it, how they preserved it, how they petitioned the Governor to make it a state park. Absolutely incredible!! Go!...

Reviews Summary

Visitors rave about the awe-inspiring, pristine cave formations and the knowledgeable, friendly staff. The park's designation as an International Dark Sky Park is a major highlight for stargazers. However, some RV campers have experienced issues with unlevel campsites, and the park's tap water quality is a concern for drinking and cooking.

"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 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."

"No photos allowed inside, but that honestly made it even better. Kartchner Caverns is unlike anything I’ve ever seen — a state-of-the-art facility protecting one of the most beautiful natural spaces I’ve ever stepped into. Being inside the Earth like that… it’s humbling and breathtaking all at once. Must see!"

Jacquie Lupro

"Majestic & otherworldly! We were extra fortunate to get spots on the monthly photography tour. Even the visitors center is beautifully designed, starting with the fascinating discovery and development story in a lovely amphitheater. Each staff member was genuinely proud of their part in the visitor experience - warm, friendly and knowledgeable. Can’t wait to return and share this special place with our visiting family and friends!"
