Duval Street
Duval Street, running from Mallory Square to the Southernmost Point marker, is one of Key West’s most lively streets. Host to museums, shops, galleries, and cafes, Duval Street is great not only for people-watching, with its many annual parades and events, but also for learning about the history of the Florida Keys, with attractions such as the Ernest Hemingway Home and Museum, and the former Strand Theater.
Dry Tortugas National Park
Dry Tortugas National Park, 70 miles from Key West, is only accessible by boat or plane, but is a worthwhile stop on any trip to the Florida Keys. An archipelago of seven beach-ringed islands, one is taken up entirely by the preserved ruins of Fort Jefferson, which stands guard over the coral, seagrass, and shipwrecks that welcome snorkelers from around the world. Popular snorkeling spots are the Historic Coaling Pier, Fort Jefferson's moat wall, and Garden Key. Boaters can explore around Loggerhead Key's Little Africa Reef and the Windjammer Wreck.
Marathon
Not to be confused with the activity, or the location of the same name in Greece, Marathon is the sportfishing center of the Florida Keys. Charters are easily arranged here for deep-sea, reef, and flats fishing. A variety of beaches and beachfront restaurants line the strip, while the former Seven Mile Bridge on the island makes a scenic path for walkers, joggers, and cyclists.
