Suggest some long walks between cities in North Jersey

I’m relatively newish to jersey and love exploring the area by walking between towns (and jersey is a great area to do this). So far I’ve done South Orange to Summit, Summit to Morristown, Bloomfield to West Orange to Upper Montclair. So what are some other areas where I can string together a few cool towns this way? Ideally like 6 miles long at minimum. I guess I’m basically just asking for areas with a couple interesting towns all in a row without too much highway, industrial stuff between them. They can be more rural or more urban.
