Fascinating if you're into staring at piles of dirt and rocks and imaging how it must have looked before falling into ruin. It's somewhat comparable to Tuzigoot in that you're on top of the structure that's sectioned off into many rooms, but it's not as preserved and it's far smaller.
What makes this exceptional is the fact that it's a piece of native history in the middle of a big city. In this regard, it's perhaps like the La Brea Tar Pits in the heart of Los Angeles.
Admission was $6, which gets you into the little museum and the park in back. The park includes one large original structure that you can walk onto by a paved walkway with several recreated buildings scattered along the roughly 1/4 mile trail.
The experience is closer to visiting Besh-Ba-Gowah over in Globe; however, you can't walk around in the ruins or climb up ladders. Unlike Globe, though, you get to walk into a couple of the recreated dwellings in Pueblo Grande, which are furnished with a few small items that you can gently handle.
It's worth a visit.
