The Florida Keys extend more then a hundred miles and are connected to the mainland by a 113-mile overseas highway. A tropical paradise with golden sands and turquoise ocean, the Florida Keys seem a million miles from the stress of the big city. Snorkeling and scuba diving through the reefs at Key Largo is a memorable experience. Key West has everything for a hot-weather, ocean-side vacation, including many quaint restaurants and watering holes. The Dry Tortugas National Park is a draw for those visitors looking to experience Florida's wilderness, and also features Fort Jefferson, one of the oldest coastal forts in the United States. Key West is one of the oldest cities in America, a fact that is brought to the fore during local ghost tours hosted by Key West Original Ghost Tours. Be sure to see the Ernest Hemingway Home and Museum, the Key West Aquarium, and the fascinating Dolphin Research Center in Marathon.
