Forever in summer, Key West is all about kicking back. Everyone and everything here seems to go at its own easy pace. But it’s not all hammock time—the diving here is phenomenal, as is the food. Travelers keep coming back for the must-eats: Cuban sandwiches, Cuban coffee, and key-lime pie, along with outstanding seafood. No surprise, the weather, the food, and the scenery have lured lots of crowds, but you can escape them with a well-timed visit in early spring—or just get out on the water where you can stake out your own private spot in the Gulf of Mexico.
