Bountiful reefs around Marathon make it a popular diving, snorkeling, spearfishing, and lobster tickling area. One of the last untouched tropical hardwood hammocks in the Keys is found at Crane Point Museum, just a few miles west of Florida Keys Marathon Airport. The vicinity of the airport is one of the most reliable sites in the United States to see the hard-to-find Antillean nighthawk. As in the rest of the Keys in summer, gray kingbirds are often seen on telephone wires along US 1 and black-whiskered vireos incessantly sing in the hammocks. Marathon also hosts burrowing owls. The Fisherman's Hospital is in the west end of the city. It is one of just three hospitals in the Florida Keys. Marathon is home to another "hospital", The Turtle Hospital, one of a handful of facilities in the United States that rescue, rehabilitate, and release injured sea turtles. Marathon derives much of its livelihood from the ocean and seafood is a staple at most restaurants. There
