Four-Wheeling

With thousands of acres of nearby Bureau of Land Management lands to enjoy, it's hardly necessary to use the park's limited trails for four-wheel adventures. You can, however, go backcountry in Arches on the Willow Flats Road and the Salt Valley Road—just don't set out for this expedition without first stopping at the visitor center to learn of current conditions. Salt Valley Road is very sandy and requires experience to drive on it.

Tours and Outfitters

Coyote Land Tours. Imposing Mercedes-Benz Unimog trucks (which dwarf Hummers) take you to parts of the backcountry where you could never wander on your own. Technical tours challenge drivers with imposing rock formations, washes, and assorted obstacles, and there are tamer sunset excursions and camp-style ride-and-dine trips. They stand by their money-back "great time" guarantee. Moab, Utah, 84532. 435/260–6056; www.coyotelandtours.com. From $59.

High Point Hummer & ATV. You can rent vehicles, including ATVs, UTVs, and Jeeps, or get a guided tour of the backcountry in open-air Hummer vehicles or ATVs, or dune buggy–like "side-by-sides" that seat up to six people. The enthusiastic owners love families and small, intimate groups, and offer hiking and canyoneering as well. 301 S. Main St., Moab, Utah, 84532. 435/259–2972; 877/486–6833; www.highpointhummer.com. From $69.
