Williams Township/Durham Township area (in the south) or Raubsville/Riegelsville. Right next to the Delaware River is a nice walking/bicycling path, along the canal. It is not paved, but well-maintained. That portion goes from Easton to Morrisville (across from Trenton). There's another portion along the Lehigh River from Easton and eventually will connect to Scranton/Wilkes-Barre areas.
