This is going to be kind of a short post....not because we didn't have a great time at Kartchner Caverns State Park but because we were not allowed to bring cameras, etc., with us when we toured the cavern so the camera stayed in the car and I didn't get any pictures anywhere in the park. I borrowed a few from the site but they aren't the greatest.
The Caverns are located 9 miles south of Benson on Hwy 90. In addition to the Caverns, there is a campground with 62 campsites (water and electric). There are several tours to choose from like the Saturday Helmet and Headlamp Tour, Big Room Tour, and the Rotunda/Throne Tour. We chose the Big Room Tour. It is 1/2 miles in length and takes 1 3/4 hours. This is considered a wet cave and every precaution is taken to ensure the growth of the cave is not affected by visitors. There are several sealed entrances to go through before you get into the cave that helps to keep humidity at the proper level. You take a tram from the Visitors Center up to the entrance to the cave.
Work was begun to open the cave to the public and the grand opening ribbon cutting ceremony was held in Nov 1999. The lower caverns opened to the public four years later. We enjoyed seeing all the beautiful formations.
After we toured the cave, we drove around the campground. It was very nice and decently spaced sites and some trees.
Keep in mind that children under 7 are not allowed in the Big Room and that you can make your reservations online. We were able to get on the next tour without reservations but I would expect things to be much busier during the summer.
There are also numerous hiking trails available in the park.
