Walnut Canyon National Monument, Flagstaff

In Walnut Canyon, visitors can hike back in time nearly 700 years. Now that's a workout! Originating at the visitors center, a rugged three-quarter-mile off-trail hike leads to cliff dwellings that stand unspoiled in the cover of the beautiful canyon walls. The strong of heart can hike deeper into the canyon on Island Trail, a breathtaking 85-foot descent into 25 rooms where American Indians once lived in the shadow of the cliffs. Bring your most reliable shoes and your spirit of adventure.
