Fantastic park for seeing the stars and getting away from Phoenix city lights. Lots of well marked trails and access to water and facilities as well as access to a county library and education center at the entrance.

I just camped in this park last night in space 17 - the family camping is about 35 sites in a big loop with a central restroom and marked pathways from each campsite to the facilities. Some sites are pull-in/back-in, and others are pull-through along the road. The lowest and highest numbered sites are closest to the staff "residences" with their RVs. Each site has a fire ring, grill, concrete picnic table and water/electric posts. I think site 18 is my favorite, and sites 17-21 are closest to the family campground trail leg that leads to the Ironwood Trail for hiking access.

I've also joined two ranger-led hikes here (Black Rock Loop for sunrise hikes) as well as a county-sponsored astronomy night with access to multiple large telescopes and an astronomy presentation. Check the park website for their activities calendar as there's a good chance you can take advantage of some organized education during your visit.
