GW Bridge to Nyack
I've heard so many cyclists talk about riding on 9W, up to Nyack, but Jenny and I only just tried it today, and it was amazing! I highly, highly recommend this ride. Crossing the George Washington Bridge was a little like crossing the Brooklyn Bridge-- beautiful views but a little slow-going from the other cyclists, pedestrians and somewhat small walkway. After the bridge there's a high-traffic intersection, and it's a little confusing to find your way to the path, but there were a bunch of other cyclists, and we pretty much just followed them. For that matter, there were so many other cyclists, that it almost felt like an organized ride.
Once on the path, there are virtually no cars, and it's absolutely beautiful, riding alongside the Hudson River. There are crazy big hills, including this one steep 2-mile climb that we probably could have skipped if we'd turned onto 9W sooner. I think there's a path that runs parallel to 9W that we took for half the ride, and then found 9W around exit 2. In Nyack there was a great deli for lunch with vegan cake and sandwiches and other snacks. The whole thing, from our apartment to Nyack was about 50 miles.
