and the Middle Keys
Marathon is a distinguished island destination in the Middle Keys, where understated luxury meets the natural beauty of the Florida Keys. Ideally positioned between Key Largo and Key West, the city offers a rare blend of tropical elegance, everyday convenience, and long-term investment appeal. As an incorporated city with its own governance and zoning, Marathon provides a refined level of structure and consistency—highly valued in a coastal market. Within the greater Marathon area, Key Colony Beach and Duck Key are celebrated for some of the most spectacular luxury waterfront living in the Florida Keys, while Coco Plum offers a more peaceful residential atmosphere defined by privacy and natural beauty. From the pristine shores of Sombrero Beach and world-class snorkeling and fishing to fine dining, marina living, and proximity to the iconic Seven Mile Bridge, Marathon delivers an elevated Keys lifestyle defined by balance, accessibility, and timeless coastal sophistication.
Gateway to the Iconic Seven Mile Bridge
Marathon is ideally located near the legendary Seven Mile Bridge, placing it alongside one of the most breathtaking drives in the world. Stretching across endless turquoise waters and open horizons, this iconic span defines the Florida Keys experience—where every drive becomes a scenic journey and sunsets, ocean views, and island tranquility are part of everyday life.
World-Class Snorkeling
In our experience, the Sombrero Lighthouse area offers some of the finest snorkeling in the entire Florida Keys. Crystal-clear waters, vibrant coral formations, and abundant marine life create an unforgettable underwater experience, making this area a true paradise for snorkelers who value natural beauty, calm conditions, and exceptional visibility.
Sombrero Beach — A Rare Island Treasure

This beautifully maintained shoreline features soft sands, stunning ocean views, and thoughtful amenities including restrooms and a park for children. It is a place where families, residents, and visitors alike can enjoy the simple luxury of a classic beach day in an island setting.
