Conveniently located near the east entrance. No reservations. First come, first serve. A short walk to the market and Watchtower. Restrooms are clean, with running water. No showers tho. Had to do the bird bath thing. The campground was clean and spacious. There were all sorts of critters about, so be sure to store all your food in the bin or else. It was cold at night, but the stars and a nice campfire more than made up for it. Woke up early and grabbed my sleeping bag so that I was nice and cozy watching the sun rise from the rim, which was just a few hundred feet from our campsite.
