If you get over to Easton, cross into Phillipsburg, NJ and ride up river to Belvedere. Beautiful stretch with very little traffic. Then cross into PA and ride up that side to Delaware Water Gap, PA. Another beautiful stretch. Only catch is that there are basically no services between Belvedere and DWG except for a small c-store/gas station in Portland. There is a season campground (Driftstone on the Delaware), but it's expensive. There is another campground in Portland or Turkey Ridge Road, but it sounds like a dump from the reviews. Another option with fewer hills is to get over to U.S. 46 from Belvedere, take that to Columbia, NJ and then cross the pedestrian/bike bridge to Portland. U.S. 46 can be busy at times, but it's not that bad. There is a shoulder, but it was rough in places when I rode it a few years ago. There are a few more services on that side as well as another expensive campground.

If you want to continue up the river, the ride through the Delaware Water Gap National Recreation Area is great. There is a walkway along I-80 from DWG to the NJ side of the river, and then you start on Old Mine Rd. Nice state forest campground about 3 miles up Old Mine--Worthington State Forest. The riding all the way to Port Jervis, NY is nice.

All this is really out of the way, though.

BTW...Is that old 7-UP sign with the radiant sun still hanging in Topton? I believe it was for a News Agency.
