"This route takes you to Moab’s high country, by local standards, and to an overlook of redrock monoliths poking up from Castle Valley. For millennia the formations Castle Rock and Priest and Nuns have preached a silent sermon to a congregation of canyons, mesas, and mountain peaks. You, too, will be enlightened by their desert oration from Porcupine Rim’s 1,000-foot altar. Riding conditions are bittersweet, and your upper body will receive a bigger workout than your legs.
The climb to Porcupine is a constant battle against sandstone ledges outcropping in the sandy doubletrack, and you’ll yank on your handlebars to lift your front wheel time and again. The rim road is more agitating than a paint-shaker and leaves you blurry eyed. And the famous Jackass Canyon singletrack descent is a true test of one’s handling savvy and capacity for high places; it’s blissful for some or a despairing walk for others. But when you factor in where you’ve been and where you’re going and the sights enjoyed along the way, Porcupine Rim truly is a world-class ride. Tread: 11.7 miles of sand, pebble, and broken slickrock doubletracks; 3.1 miles of dirt and ledgy singletrack."
