There are 120 sites, 95 of those have water and electric hookups for $25 per night. Roads and sites are paved and have a picnic table. Facilities include large, clean showers, recycling and a dump station.
In the newer B loop sites are huge and well separated, with some pull throughs, and 20/30/50 amp service. Loop A is older and has decent sites with 20/30 amp service, though all are not as large as those in loop B. There is an overflow dry camping area (Ringtail) and an equestrian camping and staging area.
We had perimeter site B11 with a lovely view of the mountains, easy access to trails and no camp sites behind us. We were able to get a perimeter site because we had made reservations back in December. The park was full each night of our stay.
We had excellent 4G Verizon cell service and internet signal.
We loved the easy access to many hiking trails into the Santa Catalina Mountain wilderness, the huge and fairly private site we had, and the quietness and beauty of this campground.
