When to go
You can capture great photographs from here any month of the year, though I prefer visiting during spring, summer and fall months because of the nicer weather. That being said, there's no bad time to get up there — even winter is splendid to capture the snowfall. Just bundle up if you visit!
Visit at night to capture a darker, gloomy view. You'll also have an empty space without pedestrians.
Sunrise is also likely to be empty. Blue hour is also nice, as you can capture the backdrop of Manhattan skyline framed between the bridge cables and traffic against the vibrant colors of the sky.
Since the temperature on the bridge can sneak up on you (especially during the cooler months) be prepared and bring along a jacket!
By using a wide-angle lens (24mm), you’ll be able to fully frame the intricate architecture of the bridge and the promenade pathway.
During the day there will be a lot of foot-traffic and cyclists, so I highly recommend using a small portable tripod (e.g., Joby Gorillapod) near the railing. A full size tripod is advisable when it's less busy, around sunrise and around midnight.
Bring along different lenses for landscape and portrait shots. There are endless opportunities to experiment with the geometry and symmetry on the bridge. Having a subject could also produce very compelling photos.
Don’t forget to use the cables and the light along the bridge as leading lines to frame your photo.
If you’re on the Manhattan side, take a stroll to Chinatown for more photo opportunities and great restaurants, like Nom Wah Tea Parlor.
Wandering around Financial District and Fulton Station for more awe-inspiring sights is also a nice experience!
