We stayed here once in March of 2020. Must have Spring Break - tons of families, tons of kids, dogs and a few old timers. There's a couple short hikes from the campground that were OK. Lots of birds, saw a couple javelinas.
There's some boat rentals and a small visitor center/general store. We had water and electric at our site. Sites can be pretty close together with boundaries undefined. Shore of the lake difficult to get to in places because of thick vegetation. East CG is maybe a little less busy than the west.
Lots of places to explore nearby - Tubac, Madera Canyon, the Town of Patagonia, Ramsey Canyon near Sierra Vista, which is a good place to resupply and other more far flung places like Tombstone.
It was to have a lake by the campground which is a little unusual in Arizona. The land is different than the Sonoran desert of Tucson but still cool. We probably wouldn't go back unless it was offseason.
