We stayed at a place called Lone Star Campground, near Bear Butte Mountain. Good power, good water, nice showers and bathrooms. Beer was cold, coffee hot, prices ok.
After 4 trips up and a few camp grounds, my vote now is for Shade Valley where we stayed last year. They had a tent set up, electricity, a fan, a light and mattress set up and ready to go. When we were done we just left it sitting there. We road from Texas and not having to haul a tent was sweet. Clean restrooms, hot water and good bands.
