Arches backcountry is mostly rough terrain, inaccessible by established trails with very limited water sources. While Arches National Park is known for its outstanding geologic features, it also contains irreplaceable cultural resources and sensitive high desert ecosystems.
Water is rarely available in the backcountry; plan to carry all you need. Primary safety considerations include steep terrain, loose rock, lightning, flash floods, and dehydration. You must know and comply with all regulations.
You must have a permit for all overnight stays in the backcountry. Permits are issued in person at Arches Visitor Center up to seven days before the trip start date and up to one hour before closing time. Each permit is limited to seven people, up to three nights per campsite or zone, for a total of seven nights.
