We used this JORBA map. Although the street names and parking areas for this trail are not indicated, look for the green-blazed trail in the NE corner of the map, west of Cranberry Lake. We parked at the southern terminus of the trail, in a pull-off big enough for 3-4 cars, on Cranberry Ledge Road. We headed west into the woods, immediately encountering a tricky creek crossing before eventually climbing and heading east all the way to the Sussex Branch rail trail at Route 206. Here we turned back. But instead of retracing the entire Waving Willie trail, we took a shortcut back to the southern leg. You can see it on the map just south of the 40 57' N line. This unmarked trail actually had a wooden bridge over the same creek that we initially encountered. They should move the bridge! It was a nice jaunt in the woods with many ups and downs, but nothing too strenuous.
