This state park is incredible. This is the only picture of I was able to take prior to being told you can't take any pictures in the Caverns themselves. Even though it would have been an incredible to take pictures it was a pleasant surprise to be able to be present to see the grandiose caverns in their full glory. I gave this four stars only because the websites not very clear on the extent of how physical the walks are. Let me explain, the caverns are described on the website by the length of time it takes for an individual to complete the tour. Maybe this is part of my assumption however I thought that 50 minutes would be a long time to walk especially because I wasn't sure how difficult the cave tour maybe. However to my pleasant surprise the cave has been made to allow the average Joe to stroll with some incline but not much. The longest tour is about an hour and a half. After taking the first tour I had wished I had done the long one. The 50-minute tour is is not physically exerting. They cart you to the front door And is more of a brief stroll in anything else. That being said I would have done the longer tour If I had known that. The short tour could be done by even someone elderly in my own opinion depending on their ability to walk for the most part. I hope this review helps people that are able to walk even with a slide incline to choose the long tour, I will be back to do the longer tour The caves were absolutely beautiful and literally jaw-dropping. I'm absolutely happy that I didn't have my phone to be able experience it first hand. The only drawback was that it is so far from where I live which is why it was disappointing being that you have to have a reservation prior to going otherwise I would have done the long tour in addition to my attendance. Overall four stars an amazing place if you haven't seen it it's definitely worth your time. Pro tip it's nice to go in the winter time The insides of the cave are about 80°. I can only imagine what that would feel like during in Arizona summer.
