Get to Loudenville, Ohio (east of Mansfield, near Mohican State Park). Just south of Loudenville, off Rt 3 is Wally Rd (R.R. 3175). Take Wally Rd past all the campgrounds and canoeing places until you get to Mohican Wilderness Campround. You can park there and speak with Ryan, he drew a great map of the trails for us. The trails begin at Wally Rd and Vess Rd at the far end of the campround.
I got these directions from Mountain Bike Review. This truly was an awesome trail.
