This is a multi use single track with numerous rocky technical sections that make for a fun descent or a challenging ascent. The trail is very narrow in places making it impossible to pass other hikers and bikers without fully dismounting and dragging your bike off the trail, which also adds to the trails difficulty. The grade is quite steep, gaining almost 1000 ft in 3 miles. Views are spectacular.
