Hiking the Porcupine Rim Trail

Most people know the Porcupine Rim Trail as one of the most famous mountain bike rides on Earth. What many don’t realize is that it’s also one of the best long hikes in Moab. The trail delivers huge views of Castle Valley, challenging elevation, and the sense of standing on the edge of the world.

I’ve hiked this trail many times, and every trip offers something new—a shifting light on the La Sal Mountains, a hawk soaring along the cliffs, or that first glimpse of Castleton Tower rising from the valley floor. Here’s everything you need to know to plan your hike.

Hiking the Porcupine Rim Trail: What to Expect

Mile 0–0.5: The Warm-Up

The trail begins on a rocky jeep road with steady uphill climbing. Expect loose stone and exposed sun. You’ll feel the elevation gain quickly.

Mile 1–2: Reaching the Rim

The trail climbs toward the rim, where the desert opens up to expansive views. This section rewards your effort with panoramas of the La Sal Mountains and first glimpses into Castle Valley.

Mile 2: The Overlook

At about two miles in, you reach the Porcupine Rim Overlook—a breathtaking viewpoint over Castle Valley. Landmarks like Castleton Tower, The Priest and Nuns, and The Rectory rise dramatically from the desert floor.

This is the most popular turnaround point for hikers. Bring lunch, sit back, and watch the shadows shift across the valley.

Mile 3–4: Extending the Adventure

If you’re up for more, continue along the rim. Each bend offers new perspectives and more solitude. Beyond 4 miles, the trail begins its descent toward the Colorado River—a section better suited for mountain bikers.

Best Time to Hike

• Spring (Mar–May): Wildflowers along the Sand Flats Road and comfortable temps.

• Summer (Jun–Aug): Only safe in very early morning; extreme heat risk.

• Fall (Sep–Nov): Crisp air and golden light—ideal for photography.

• Winter (Dec–Feb): Quiet and peaceful, but icy patches possible at the rim.

What to Bring

• 3 liters of water minimum

• Sun hat, sunglasses, sunscreen

• Sturdy hiking shoes with good traction

• Snacks or a packed lunch

• GPS or offline map (Gaia, AllTrails, or similar)

• Camera—wide-angle lens for rim views, zoom for Castleton Tower

Photography Tips

• Sunrise: Best light on Castle Valley, but the hike requires an early start in the dark.

• Midday: La Sal Mountains stand out vividly against the red rock rim.

• Sunset: Rim cliffs glow, but watch your timing—don’t hike back in the dark without a headlamp.

• Best spot for photos: Porcupine Rim Overlook at mile 2.

Final Thoughts

The Porcupine Rim Trail is one of Moab’s best long hikes. It’s challenging, rewarding, and gives you a front-row seat to Castle Valley’s dramatic towers. While bikers may dominate the full route, hikers who explore the rim section will find solitude, scenery, and a chance to experience Moab’s backcountry beyond the national parks.

Bring water, respect the cliffs, and take your time at the overlook. This is the kind of hike that stays with you long after your boots are dusty.
