Marathon is set on 13 islands in the Florida Keys and known for its beaches and barrier reef. Loggerhead turtles nest at Coco Plum Beach and Sombrero Beach. Curry Hammock State Park has a sandy shoreline and mangrove creek. In addition to the beach, the Dolphin Research Center offers interactive demos in a shallow lagoon. Near the City Marina, Crane Point features a tropical forest, bird-rescue center, and natural history museum. There's plenty for you and your family to enjoy in Marathon.

In Key Colony, whether you are a full time resident, seasonal resident, or visitor, you know what a special place it is. Not only are you enjoying a tropical paradise, you are among a great group of people that have kept this little island city the “Gem of the Florida Keys” for more than 60 years. We do ask that our residents and visitors protect our beautiful reef environment, the safety of each other, and our friendly tropical lifestyle. Our famous sign, “Honestly now, what’s your hurry?” is not just a reminder that you are off the highway, it is an invitation to enjoy our city, by slowing down on land and in our canals; to “share the road” with our many pedestrians, canal boaters, paddlers, swimmers, and manatees. Welcome to Key Colony.
