Key Colony Homes for Sale

One of the hidden gems of the Florida Keys is the close-knit, seasonal community of Key Colony Beach. Because of its tight-knit community and abundance of charm, it was nicknamed years ago the “Gem of the Florida Keys.” This small island is accessible via a small bridge off Overseas Highway and a one-lane causeway. It has a fantastic location roughly one hundred miles south of Miami, on the oceanside of the Middle Keys, at Mile Marker 53. Key Colony is home to lovers of the outdoors, vacationers, and fishing enthusiasts. The winter population peaks at around four thousand, but usually, there are around seven hundred residents in Key Colony Beach. Phil Sadowski founded and developed the city in the early 1950s, and in 1957 Key Colony Beach was incorporated. It consists of two hundred and eighty-six acres and encompasses three miles of canals and roughly one thousand four hundred homes. 

Key Colony also boasts one of the Florida Keys’ few private white sand beaches where seven-day vacation rentals are allowed. Further adding to its desirability, Key Colony Beach offers a few boutique hotels, a deep-water marina, charter fishing fleets, several locally-owned shops, walkable home-town restaurants, and fantastic snorkeling opportunities at the reefs just offshore.
