The trail starts at the right corner of the parking lot. The trail sets off over a hillside; intersects with an old field road; this road meanders through the park and loops back on itself.

The proposed Hunterdon Highlands route will head from Long Valley to Spruce Run and then north to Charlestown Reservation (then south again through the Musconetcong Gorge and on to the Delaware River).

10/18/03.  The path is like a crooked-stemmed lollipop.  The orange trail heads northwest up the hill and then heads southwest and south.  The trail comes to an old field road surrounding an overgrown field (with hundreds of autumn olive shrubs).  The old field road leads in a small circle back to the entrance onto the road from whence you return to the parking lot.
