Hell Canyon is one of gnarliest trails in the Manti-La Sal National Forest Service without man-made features. Hells Canyon is located in the Pack Creek area on the South side of the La Sal Mountains.
The trail begins fast and flowy, at 8800 ft in high aspen groves and evergreens. You'll eventually descend into scrub oak with nothing too challenging. Now that you have found your groove you'll pop out of the trees and come to an overlook of the Moab Valley. From here, the whole trail changes! Now the trail parallels the top of Hells Canyon and becomes steep, loose, rocky, and super gnarly.
The upper section can be ridden by most riders, but there is no bailout point so you'll need to be an expert rider to complete the whole trail.
