Ok, we are going o be doing a 3 day-2 night backpacking trip next week. Probably in the Catskills but certainly open to the Delaware Water Gap area as well. Since this is our first overnighter - and I'm 67 y/o, we are looking for a 15-20 mile MODERATE trail. Now we are not wanting to walk in straight boring fields, but want to keep steep elevations and scrambles to a minimum. Nice views are a plus. Any suggestions?
