Brooklyn Bridge
This walkway is 1.1 miles long. It is elevated above the car traffic and has a separate section for runners/strollers and cyclists. It is one of New York's most famous routes connecting Manhattan and Brooklyn. If you've never experienced this route before, you must! It's probably the most "Instagrammable" route on the list (because did it really happen unless you post a picture of it on the Internet?).
Where: On the Manhattan side, the pedestrian walkway starts across from City Hall in lower Manhattan on the Manhattan side of the East River.
