High Peaks...easy access 2 or 3 pitches

I'll be climbing with my son in the High Peaks in mid July (I know, HOT!). Anyway, we'd like to find a climb or two that has easy access from a local campground (and hwy 25) and only a couple of pitches to be able to get in a couple of climbs. Any recommendations for particular campgrounds (we'd love to find one that has flush toilets and showers, but not necessary). Thanks in advance to all who offer assistance.
