Some of the other camping areas seemed less spacious and private, but we really liked our site in the tent-only Cactus Campground. It had a shade shelter, a picnic table, and a dirt tent pad. There was also a fire ring with a grill grate, but a burn ban was in place. The water faucet was just across the street and there were clean restrooms (with hot showers) up the road at the next campground. Even with some light pollution from town, the stars were beautiful.
We only stayed for two nights--not nearly enough to explore this incredible park. We're hoping to go back before it gets too warm.
