Porcupine Rim from Sand Flats is a 12.7-mile, one-way route with steep climbs and exposed slickrock. It is a Class 4 scramble; expect sections where you must dismount and walk. The trail sits in full sun with little shade—carry at least 1 gallon of water per person. Start early and use a shuttle to avoid backtracking; the desert skyline rewards the grit.
Technical Scramble, Class 4
Panoramic desert vistas including the La Sal Mountains, Navajo Sandstone formations, and canyons.
• Utilize shuttle services for a one-way trip to avoid backtracking. • Start early, especially in summer, to beat extreme heat. • Arrive midweek to secure parking and easier access. • This trail is not suitable for young children; plan for older youths or adults.
