A rider from New York recently submitted PA 191 which takes you through the Pocono Mountains and the Upper Delaware River Scenic and Recreational Area. He stated that he "Found this one by mistake, but what a find." I completely agree.
I've ridden it several times and it is a road that I look at anytime I plan on heading north into New York. Once you cross the bridge to Hancock, NY, you have several options:
1) Take NY 97 to backtrack south along the Delaware and enjoy the infamous 'Hawks Nest' with it's spectacular views of the river.
2) Pickup NY 10 and experience the wonderful scenery provided by the Cannonsville Reservoir.
3) Catch NY 30 which is a great route through the heart of the Adirondack Mountains.
PA 191, along with anyone of the NY routes, will provide a good day of riding.
