I'm so used to only being able to look at ruins from behind a fence or other marker that separates visitors from that which is on display. But here, you can walk into the ruins and explore them fully. We sat in on a talk about the history of Casa Grande Ruins, and it was informative and easy-to-digest. It was not too crowded when we came here, and it seems like this is often the case.
The small gift shop and visitor center added a nice touch to this park.
