This epic backpacking route is extremely remote and little-traveled. You could easily spend hours, if not days, hiking the Ouachita NRT without seeing another human being! "In a ranking of U.S. long-distance trails on a number of criteria by Backpacker Magazine, the trail ranked third for solitude3 and fourth for signage," says Wikipedia.

This solitude is largely due to backpackers choosing to head to more famous trails, such as the Appalachian Trail, for their epic multi-day. Oklahoma and Arkansas? Not such a hot backpacking destination.

"While the heartland of America is usually dismissed as coffee-table flat, rather than coffee-table-book pretty, the Ouachita Mountains, which form the spine of this east-west trail and undulate from 600 to 2,600 feet in elevation, deny the stereotype," write Taryn Jory and Andy Dappen for Backpacker Magazine. "The rolling mountains and valleys, smothered with oak, hickory, maple, and pine, are carved by cobbled creeks and capped with the occasional sandstone rooster comb. This is a place that will win you over with its subtle beauty, not with its grandeur."
