Recommended Users: Mountain Bikers, Hikers. Singletrack trail. 6.7 miles in length. Difficulty: Moderate/Easiest. Mostly smooth singletrack (with a few rocky sections thrown in to make it interesting) the Jem is known for its fast downhill riding. At about 0.75 miles, there is one nasty steep downhill section that takes the trail from mesa top to wash bottom. Ride this section with care (good riders only). You’ll know when you get there as a fenceline rideover comes just before the drop off the mesa. The trail continues in the wash for a short bit before popping out back up to the surface.This trail is a classic. The first to be ridden in the area by early mountain biking pioneers, it inspired the trail system that exists today. There are great views of the numerous surrounding mesas, the Virgin River, and the sandstone towers of Zion National Park.SAFETY NOTE: One section of the Jem Trail is now ONE WAY. From the Jem Trailhead to the intersection of Goosebumps Trail (1.41 miles) the direction of use is North (downhill). Riders returning to the Jem Trailhead will use Dead Ringer Trail.Mountain Biking Loops: There are endless loop possibilities.
