Comparing to Cave Creek up the road, I'd definitely choose Grayback for families. It was sunnier, the creek was easily accessible, there is no bear issue, and pulling in at 7pm on a summer weekend we still had our choice of campsites. The creek has a few swimming holes and the campground has an interpretive trail. The day use picnic area is free. The host was not there when we visited, but the campground was clean and other campers were friendly. Some sites were practically on top of each other, but there were many that offered more privacy.
