Surrounded by red rock and scrubby piñons, the park's only campground is 19 miles from the Arches National Park Visitor Center. It's open year-round, but from March to October the sites are available by reservation only due to high demand. Book months ahead.
Facilities include drinking water, picnic tables, grills and toilets, but no showers (for those, try a place in Moab). RVs up to 30ft are welcome, but generator hours are limited; no hookups.
