Beautiful, peaceful, so many trees and lots of shade. Some sites are impossible to reach without 4 wheel drive but many shady areas near the bathrooms and water are relatively easy to reach. You may scrape rocks in a super low car like ours. The fee is $15 per night and they have water spigots, a bathroom, concrete picnic tables, bear boxes, and a fire pit with adjustable grill. The road gets a bit threatening in the last 2 miles or so before the campground. You shouldn't go any further however, unless you have 4WD or a good truck, the road beyond this campsite is not maintained much and is "drive at your own risk".
Across Mt. Lemmon Rd. is a trailhead for an ATV trail marked "Rice Peak 7 (miles)" much closer than the other hiking trails, that we hiked along for a bit and it was stunning, and we saw many lovely secluded sites for camping back there which I assume are free dispersed camping areas with no amenities, and we also found a trickle of snowmelt forming a tiny creek in the riverbed while hiking there, a cool creepy cave in the wall, and lots of neat rocks. Lots of birds and little animal sounds at night shows you the life of the forest. Neat bugs too!
