The Overseas Highway connects Key West to the rest of the Florida Keys, making several worthwhile day trips possible by car or tour.
Drive the iconic Seven Mile Bridge north to Bahia Honda, widely considered the best beach in the Keys, with turquoise water and views of the old railroad bridge.
The self-proclaimed "Sportfishing Capital of the World," about 75 minutes north, with the History of Diving Museum and excellent seafood shacks along US-1.
