RECOMMENDED: 101 things to do in New York City in the summer
New York City's more than 50 outdoor pools opened for the season at the end of June, offering New Yorkers plenty of spots to cool off during the hot summer months. Add to that list another new swimming hole: Last Friday, a pop-up pool opened on Pier 2 of Brooklyn Bridge Park. The small basin is 3.5 feet deep and can fit 60 swimmers at a time; to ensure that there isn't overcrowding, patrons are let in during timed sessions. (You'll have to queue up for a wristband—be prepared, as lines have been long.) Check out our photos from opening day, and for more information, visit Brooklyn Bridge Park's website.
