After hiking parts of the Highland, red, white, yellow, blue and connector trails in Allamuchy most of the day but not scaling any peaks, I decided to try and find a way up Upper Pohatcong. I got as far as two 'for sale' lots on a new road of macmansions off of Highland Road, west of the high point. One could probably easily trespass there but I didn't. I also scoped out O'Brien Road by the radio towers - bristling with 'no trespassing' signs. Finally I explored possible access from the west side of the train tracks along Rockport Road in Hackettstown. This looks like the most interesting route. There may be Rockport Wildlife Management area fencing. But it was getting dark so I never made it up Upper. Now that I know how to do it, I may try it next time I'm in the area. It is wonderful that Upper Pohatcong still looks pristine from Centennary College - development is not visible from there.
