1. New York City
Mayor Michael's Bloomberg's PlaNYC sustainability plan is paying off, as the iconic Times Square has become pedestrian pathway off-limits to cars, and bike lanes are going in (sometimes controversially) across the five boroughs. New York City's Walk Score is an impressive 85 out of 100, with 90% of its neighborhoods ranking highly for walkability. America Walks ranks New York's most walkable neighborhoods as Little Italy, SoHo and the Flatiron District.
