Take a dip into Astoria Pool and beat the heat all summer long. This Olympic-sized swimming pool was built to hold 3000 of your closest friends, and is accompanied by a diving pool and a wading pool for the wee ones.

Originally opened in 1936, Astoria was the model for 11 other swimming facilities in New York City. It’s the only one with a clear view of the Triborough Bridge, and boasts views of the Manhattan skyline. The best part of all? Entrance to the pool is free. But, make sure you bring a combination lock with you to secure your stuff. You’re not allowed into the pool without one, and you probably wouldn’t want anyone messing with your stuff while you’re splashing around anyway.
