To the south of Miami are the Florida Keys, a chain of coral islands that extend for more than 110 miles between the Atlantic and the Gulf of Mexico.

Until a devastating hurricane in 1935, they were linked by a rail line extending to Key West, from which there were boats to Havana, Cuba. The boldly engineered Overseas Highway, US 1 now runs over 42 bridges and numerous artificial causeways to the southeastern tip of the United States.

Many people immediately think of Key West when they ponder the best places to visit in the Florida Keys, but there is much more to see. The little islands of Sands Key, Elliot Key, Cotton Key, and Old Rhodes Key, lying off Biscayne Bay, are now part of the Biscayne National Underwater Park, established in 1980. Off Key Largo are the John Pennekamp Coral Reef State Park and the Key Largo National Marine Sanctuary.

The Florida Keys are filled with wildlife, scattered beaches, beautiful resorts, and plenty of water adventure opportunities, including snorkeling, diving, and swimming with the dolphins. Tourists can find plenty of interesting history here, too, especially thanks to pirates who used to call the Keys home.

Plan your trip to the islands with our list of the top attractions in the Florida Keys.
