We stayed here on a whim on our way from Arches to Zion and couldn't have been more surprised with what we saw. There was no cell service, but that was good with us. Less than 10 minutes from the campground were some spectacular petroglyphs that require absolutely no hiking, just some walking on a boardwalk. Bring your binoculars or telephoto lens because they are a distance away. The main location has one of the pay spy glass things, but we generally don't use those.
The campground itself was PACKED with all varieties of campers- tents, roof top tents, small trailers, large trailers, and motorhomes. The hosts seemed to be active and visible. Toilets and dump stations were on site. Water was at the restrooms (though I'm sure there are hookup sites, we just didn't need one.)
The history of the campground was what really took us by surprise. A mormon settlement came through and created an orchard that still exists today. During certain seasons you can pick the fruit (probably best to ask the host or the visitor center first, though!)
