Nothing brings back summer childhood memories of melted ice cream cones and belly flops quite like the smell of chlorine. Poolside is the destination for area residents who can’t bear the heat and humidity of Washington’s summer. City and county recreation departments list neighborhood pools, but unexpected spots to cool off also can be found at area hotels. Read below for where you can take a dip.

The Hilton Washington on Embassy Row (2015 Massachusetts Ave., NW; 202-265-1600) is half a block away from the Dupont Circle Metro station.

Maryland’s Montgomery County public pools are worth checking out. Many of the indoor pools are equipped with water slides, bridges, and toddler pools. Some outdoor pools offer special features—the Martin Luther King Jr. Pool in Silver Spring, for example, has a circulating Lazy River for inner-tubing and a shallow lagoon.

Pools in the District of Columbia are free for residents and are open from June until early September. The Department of Parks and Recreation divides the pools into three categories: indoor, outdoor, and walk-to-learn outdoor pools—essentially neighborhood children’s pools.
