1. Siesta Beach
Where: Siesta Key
As its name implies, Siesta Key is the place to relax. The expansive beachfront rarely feels overcrowded and the fine quartz-crystal white sand stays cool to the touch, so be sure to dig your feet in whilst reading your favorite magazine. (Ahem.) Pack your cooler with your adult beverages—no glasses allowed—and, if you bring a designated driver, get there early as parking fills up quickly. Should you feel the need to exert yourself, kayaks and paddleboards are available for rental.
