We camped here for a night before heading to Hetch Hetchy to do some backpacking.  It's super close to the Hetch Hetchy entrance, so very convenient if you are trying to get an early start for backpacking.  We got in just before sunset on a Friday, and managed to get a walk up site. Campground was pretty full, but as expected in August.   Very clean campground.  The camp host had wood available for sale.  The most memorable part were COWS that had wandered near the campground.  We could hear their cowbells through the night, but not in an annoying way.
