Rocky singletrack with lots of flowing hard-packed singletrack, mostly downhill util the end where you climb back out to the beginning.
Start out at the access road by the stone house off of Skyline Drive. Go down to the tower and turn right down the power line, look for the trail to start on the left. Enjoy ~1.5mile rocky singletrack that crosses another power line. Once you hit the T take a left up Mossy Trail and then stay left onto the access road which loops around back to the start.
