Goosebumps and Cryptobionic
Goosebumps and Cryptobionic are newer trails that offer alternatives to the classic JEM and Hurricane Rim rides. Cryptobionic is an easy ride, 3.6 miles long with 250 feet of elevation change. Goosebumps undulates along the edge of the mesa and is a moderately technical 5.1 miles that includes about 1.5 miles of dirt-road and washbottom. This ride takes JEM uphill, then follows Goosebumps down.
