Sky & Swim · DC
The height limit means Washington will never have a skyline pool, and that turns out to be the interesting part — fourteen floors is the top of the world here, and the view is the Capitol dome rather than a wall of glass.

Washington has almost no true rooftop hotel pools; the WAVES deck here is the exception, looking over the Potomac waterfront and the DC skyline. Heated, guest-only, and an actual swim — not a bar with a puddle.
Deck 11 is the largest rooftop pool on Capitol Hill and the only one where the Capitol dome is genuinely the view rather than a rumour of one. Eight hundred square feet of water inside an eight-thousand-square-foot deck, open for the season, with day passes — the most accessible good pool in the city.
Fourteen floors up on the 14th Street corridor, which in Washington counts as altitude, with the city skyline opening out around the deck. Memorial Day to Labor Day, 8am to 8pm, and a day pass can come with a cabana. A real swim by day, Hedy's bar crowd after dark — so take the morning lap and go early.
