When summer temps threaten to hit triple digits, there's one place in Miami that stays a consistent 76 to 78 degrees: the historic Venetian Pool in Coral Gables. Fed by a natural spring and drained nightly, the 820,000-gallon pool built in 1923 is ideal for a midday soak if your backyard is waterless or you find yourself terrorized by obnoxious drunks when you venture downstairs to your apartment's pool. This isn't just any neighborhood pool, either — with waterfalls, rock features, and faux Mediterranean ambiance, it's the only swimming hole in America on the National Register of Historic Places. For $13 for adults and $8 for kids (with extra discounts for Coral Gables residents), you'll get the most bang for your buck if you get there early and make a day of it. Bring your own snacks to avoid the lines at the concession stand, and put the money toward a chair rental so you'll have a place to sprawl out and stash your sunscreen. Take one last dip before the pool closes (around 4:30 to 6:30, depending upon the day and time of year) and ride home with the windows down so you can feel the hot wind against your wet hair. And if even that fails to shake your stubborn summertime blues, you have full permission to pull into the nearest parking lot and rock back and forth in the air conditioning.
