Mr. Wizard and Outdoor, you are both right! Sunset and Azalea are the coolest campgrounds -- literally -- because they are at 6500 feet, and are located next to Grant Grove.
The campgrounds down at the Cedar Grove end of the road are at a lower elevation but are right near the Kings River -- this shot was taken in Sentinel Campground, right from our campsite, in early May of 2011:
Not a very dramatic shot, but you can imagine the sound of the rushing water tumbling over the submerged boulders -- built in white noise, and built in air conditioning!
Which was a good thing, because the valley floor can get pretty hot during the day, since it is below 5000 feet in elevation. Fortunately, the nights almost always cool off substantially.
