Marathon & Duck Key Real Estate & Neighborhood Guide
In the heart of the Middle Keys, offering deep-water canals, a local airport, marinas, and waterfront homes.

Living & Buying Real Estate in Marathon & Duck Key
Located in the heart of the Middle Keys in Monroe County across Knight’s Key, Boot Key, Key Vaca, Fat Deer Key, Crawl Key, and Grassy Key (plus neighboring Duck Key and Key Colony Beach), the City of Marathon serves as the boating and aviation hub of the central Florida Keys. With its own 5,000-foot runway at Florida Keys Marathon International Airport (MTH), private jet and charter owners can land minutes from their waterfront dock.
Duck Key is a picturesque island community built across interconnected residential islands (Plantation, Yacht Club, Harbour, and Indies islands) bordered by turquoise canals and Hawkes Cay Resort & Marina. In Marathon and neighboring Key Colony Beach, neighborhoods such as Sombrero Beach, Coco Plum Beach, and Boot Key Harbor offer single-family concrete homes with wide deep-water canals.
Unlike many areas of the Keys that require 28-day minimum rentals, Marathon and Key Colony Beach permit licensed seven-night vacation rentals, making this market highly attractive to both second-home buyers and vacation-rental investors.
