The way points of this bicycle route:
Turn South off Bridge onto Bigler Street (one way) Then continue o Left onto Henry Hudson Drive continue for 8 miles north alongside river and trees to climb Alpine onto 9w.
From now to Nyack, local road rules insist cyclist are no more than one abreast - this is enforced - though technically it's not a 'legal' law
Lots of bike racks and fantastic muffins. On your return you could try Henry Hudson Drive - if you didnt on the way up.
