What Travellers Say
Reviews Summary
Visitors often find Casa Grande Ruins National Monument to be an amazing and unexpected stop, especially appreciating the free admission and the chance to explore ancient structures. While some note that the visitor center hours can be inconvenient, the historical significance and unique glimpse into the Hohokam civilization make it a worthwhile detour for those interested in archaeology and history.
"This was an amazing unexpected stop off of I-10 from my drive from Phoenix to Tucson. I arrived an hour before they closed at 3. The guy who worked there was super nice. Entry is free to see the ruins and you can walk right up to it. Be aware that some parts of the visitors center such as the theater and the gift shop close early before they close up the park itself. Definitely stop by if you are interested in historic ruins like this."

"Archaeology is an interest of mine, and I make sure to set aside time to visit any place that preserves ancient history, whenever one is nearby. A visit to Phoenix, Arizona meant an opportunity to visit Casa Grande Ruins National Monument.
This monument preserves the structural dwellings of the Hohokam people who lived and thrived in this desert area. The centerpiece of this attraction is the big house, which is only partially intact, as some of it has eroded over time. There is a roof that was built in more recent times, presumably to help protect the structure. It looks a little odd, and certainly not natural, but I get why the National Park officials did this.
There are other, smaller structures surrounding the big house, plus educational information available as you walk around. No one is completely sure what this structure was used for but, given the presence of holes in the sides of the structure that align with the solstices, there is a good chance that astronomy was part of its purpose.
The parking lot at Casa Grande Ruins National Monument is large, and there is a visitor’s center and bookstore. One thing to keep in mind is that the visitor’s center may not be open when you visit, for example on Sunday’s during part of the year. But the monument itself will still be open for exploring the structures, even if the visitor’s center is locked.
Casa Grande Ruins National Monument isn’t very big, and you can be in and out in about an hour or so. It’s certainly a site worth seeing, and a good side trip option for archaeological lovers who happen to be in the Phoenix area."
