Starting from Lehigh Connector North, Shanahan - North Fork Trail climbs steeply through a forest area spotted with trees. After some climbing, the trail intersects with the Cragmoor Connector trail - turn left at this intersection to stay on the Shanahan - North Fork Trail.
Again, the trail ascends steeply, not contouring at all. Pass Shanahan Connector on your left and continue straight. Eventually, after the steepest portion, this trail terminates at the Mesa Trail.
