It's on 2 of my lists. Each entry below is what I wrote about it there, with my verdict on that list, the fullest first.
Spring is the perfect weather for walking the bridges. The Brooklyn Bridge gets all the attention but the Manhattan Bridge and the Williamsburg Bridge are better walks in my opinion. Less crowded, wider paths, and equal or better views.
My recommendation is to walk the Manhattan Bridge from DUMBO to Chinatown (or the reverse). The south side pedestrian path has unobstructed views of the Brooklyn Bridge and the skyline and you can have the whole path nearly to yourself on a weekday morning. The walk takes about 20 minutes and it’s flat and paved.
The Williamsburg Bridge is my favorite for sunsets. Walk from the Lower East Side to Williamsburg, stop in the middle for photos, and end your walk in Williamsburg for dinner. It’s about a 30-minute walk and the views of the city on both sides are spectacular.
While the Brooklyn Bridge steals the spotlight, let’s talk about the lesser-known Manhattan Bridge. Construction began in 1901 and the bridge was officially put to use in 1909. Clocking in at over 6,000 feet long (about 1.3 miles) the Manhattan Bridge is a suspension bridge that connects New York City and downtown Brooklyn.
Crossing the Manhattan Bridge is a top non-touristy activity, offering epic views often enjoyed without the crowds of its famous counterpart. Though less aesthetically pleasing, its breathtaking views make it a must-do in NYC.
