Just south of highway 60, West of Superior, AZ (about 4 miles). Paved road to the turnoff for the campsite and then dirt but not too rough. My Prius made it just fine. Though there are definitely some roads farther on that are extremely uneven granite dells.

Two pit toilets are the only amenities, but there is plenty of hiking. You can hear road noise from highway 60. There’s a nearby mine and I occasionally heard muffled explosions but I did not feel them. On two of the days I was there I saw or at least heard low flying fighter jets (but within FAA regs) go by and a couple of multi-rotor helicopters. Had the skies not been overcast I’d have seen all of them. They were very loud but it was maybe five minutes total out of my week-long stay.

There’s no WiFi, even if you have a yaggi antenna. There’s enough cell service for text and phone calls (maybe/iffy) on the Verizon network.
