For most visitors to the Florida Keys, Key West is their ultimate destination. And while the southernmost point is undoubtedly the archipelago’s most popular, there are plenty of other places to see and things to do as you make your way up and down the Overseas Highway.

Even if you want to rest your head in Key West each night, ferries and seaplanes shuttle visitors to the Dry Tortugas—a spectacular 19th-century military fort-turned-national park 70 miles west of Key West—each and every day.
