Middle Keys Island Community
Welcome to Marathon, a ten-mile island community in the heart of the Florida Keys, known for its beaches, turtles, and fishing.
Marathon is a city in the middle of the Florida Keys, in Monroe County, spread across a roughly ten-mile chain of islands between Key Largo to the northeast and Key West to the southwest. U.S. Highway 1, the Overseas Highway, runs the length of the community, and the Seven Mile Bridge marks its western approach. The city is home to about 9,700 residents. Marathon grew from a fishing and railroad settlement into one of the Keys' principal communities, and its economy remains tied to the water. Commercial and charter fishing, boating, and tourism anchor local life, and the city serves as a hub for the Middle Keys. Its central location makes it a convenient base for exploring the entire island chain. The community is known for a distinctive mix of natural and conservation attractions. Sombrero Beach offers a sandy shoreline for swimming and snorkeling, while The Turtle Hospital operates as a working sea-turtle rescue and rehabilitation center that draws visitors to its educational tours. Crane Point Hammock preserves hardwood hammock, maritime heritage, and nature trails, and the nearby Dolphin Research Center focuses on marine mammal education and care. Marathon offers a relaxed, water-oriented lifestyle. Fishing, diving, snorkeling, and boating are woven into daily life, and the surrounding waters of Florida Bay and the Atlantic provide year-round recreation. Public schools belong to the Monroe County School District, with campuses including Marathon High School and Stanley Switlik Elementary. Marathon appeals to residents and second-home buyers drawn to the Keys' island lifestyle, natural environment, and strong sense of community, and its location places Key West and Key Largo each within an easy drive.

City Guide
Marathon's housing stock reflects its island setting and tourism economy. The market includes canal-front and oceanfront single-family homes, elevated Keys-style residences, condominiums, and mobile home communities, along with properties oriented toward boating and waterfront access. Development is constrained by the islands' narrow footprint and environmental regulations. The mix of permanent homes, vacation properties, and rentals serves both residents and the Keys' visitor economy.
Marathon extends across several of the Middle Keys islands, including Vaca Key, Knight's Key, and Boot Key, linked by the Overseas Highway. The city's neighborhoods range from canal-front subdivisions and oceanside communities to the denser commercial corridor along U.S. 1. Boot Key, with its harbor and municipal marina, anchors the boating community, while Sombrero Beach Road leads to the city's best-known shoreline.
Marathon offers a relaxed, water-centered island lifestyle. Boating, fishing, snorkeling, and diving are everyday pursuits, and the community's docks and marinas are central to its identity. Residents and visitors gather at Sombrero Beach, waterfront restaurants, and community events throughout the year. The pace is unhurried, and the ocean is both playground and workplace, giving Marathon the easygoing character associated with the Florida Keys.
Marathon's students attend the Monroe County School District, with campuses including Stanley Switlik Elementary, Marathon Middle School, and Marathon High School serving the Middle Keys. The district is notable for its island geography, with schools spread along the Keys.

Marathon is connected to the rest of the Florida Keys by U.S. Highway 1, the Overseas Highway, which runs the length of the city and links it to Key West to the south and Key Largo and the mainland to the north. The Seven Mile Bridge, at the city's western edge, is a defining element of the drive. The Florida Keys Marathon International Airport provides general aviation and regional air service, and travel is otherwise primarily by car and boat.
Recreation in Marathon centers on the water. Sombrero Beach offers swimming and snorkeling, while fishing ranges from shoreline and bridge spots, including the Seven Mile Bridge, to inshore flats and offshore charter trips.
