The Upper Campground is a gem of a place to camp, nestled among the redwoods on the eastern facing side of a ridge (complete with hiking trails) and a creek.  The Madrone group campground is across Sir Francis Drake Blvd (I personally think it's less scenic but more open).  The only reason I took off a star is the campground's proximity to the road, which is not extremely busy but can be noisy if you are camping in a tent.  Were it not for the noise, we'd go back again and again and again.
