U.S. 1, Florida Keys
Leaving the mainland for the 120-mile-long island chain of Florida’s Keys, travelers enter a paradise of beach bars, water sports, and Parrotheads (Jimmy Buffett fans). From Key Largo to Key West, the overseas highway strings the islands together like beads, running past lighthouses, underwater coral-reef parks, and across 7 Mile Bridge—one of the longest bridges in the world.
Where to Stop: On the island of Islamorada, travelers can swim with dolphins at the historic Theater of the Sea. theaterofthesea.com
