The trailhead is on Green Mountain Road, which is the first gravel road to the West, 0.5 miles north of Jacks Fishing Resort. Travel 1.3 miles on Green Mountain Road to the Syllamo parking area on left. Well marked.
This would be a fun trail if it was at all maintained, but there are lots of downed trees and briars on the trail. According to the locals, it is really only well-maintained just prior to Syllamo's Revenge bike race.
At just over 7 miles, the trail is most easily accessed from the White River Bluff Trailhead where the trail practically runs through the parking lot. This loop is marked with orange blazes on carsonite posts. The loop is rideable either direction. This route was ridden counter-clockwise from the parking lot.
Warning: once you cross Green Mountain Road toward the end, the trail becomes hard to find and very overgrown.
