Fodor's Expert Review Riggs Spring Loop Trail

One of the park's two true backpacker trails, this rigorous 9-mile path has overnight options at three campsites along the way. You'll journey past groves of twinkling aspen trees and the eponymous spring close to the campsite. Start at either Yovimpa or Rainbow Point and be prepared for 1,500 feet of elevation change. Campers need to check in at the visitor center ahead of time for backcountry permits. Difficult.
