Why Live in Duck Key

Duck Key, located in the Florida Keys, is a small island community known for its resort-style living and upscale atmosphere. Positioned between Marathon and Layton, Duck Key features waterfront homes with Bahamian-style conch architecture, many with private pools or docks. The island is centered around Club Duck Key, which offers tennis courts, pickleball courts, and an outdoor pool. Residents can also enjoy the Duck Key Marina for boat storage and the nearby Hawks Cay Resort, which includes fine dining options like Angler and Ale and Sixty-One Prime. For adventure seekers, The Lagoon on Grassy Key provides an obstacle course and wakeboarding at Keys Cable Park. Curry Hammock State Park, located 6 miles away, offers a secluded spot for beachgoers and kayakers. Community events such as happy hours and holiday festivals are common, and the Florida Keys host unique attractions like the Underwater Music Festival and Hemingway Days. Stanley Switlik Elementary, a highly rated school, is 13 miles away on Boot Key. While Duck Key is primarily car-dependent, Miami-Dade County bus routes are accessible in Marathon, 12 miles away. The closest grocery store is Publix Super Market, also in Marathon.
