Sunset Key stands as one of Key West's most exclusive residential enclaves, offering a rare blend of private island seclusion and convenient access to the vibrant energy of Old Town. This 27-acre man-made island, formerly known as Tank Island, sits just 500 yards offshore in the harbor, providing residents with a tranquil retreat while keeping the charm of Duval Street and Mallory Square within a short ferry ride. The community features privately owned single-family homes on individual parcels, creating a neighborhood of custom residences amid a resort-like setting that emphasizes privacy and refined island living.
Historically, the island was developed as part of Key West's planned resort framework, transforming from an industrial site into a purpose-built luxury destination in the 1990s. Its man-made origins contribute to elevated building sites that help mitigate some flood risks compared to lower-lying areas in the Keys. Today, it operates as a cohesive community where residential ownership integrates seamlessly with hospitality services, fostering a lifestyle that feels both exclusive and supported.
Location and accessibility define much of the appeal. Residents and visitors arrive exclusively via a private ferry from the Opal Key Resort & Marina near Mallory Square, with crossings typically lasting 7 to 10 minutes. The service runs on a schedule during the day and offers on-request options overnight, ensuring 24-hour connectivity without the need for personal vehicles on the island. Mainland parking is provided in a covered garage at the departure point, streamlining daily commutes and guest visits.
The lifestyle on Sunset Key revolves around relaxation and understated luxury. Days might begin with coffee overlooking private beaches or a round of tennis, followed by spa treatments or a swim in the resort pool. Evenings often feature dining at the acclaimed waterfront Latitudes restaurant, with room service and concierge support enhancing the effortless feel. The pace is intentionally slow, with brick-paved paths designed for golf carts, bicycles, and pedestrians rather than cars, promoting a peaceful, resort-inspired atmosphere.
Real estate on the island consists of high-end single-family homes, many waterfront or beach-adjacent, with recent sales reflecting strong demand in the luxury segment. Properties range from multi-million-dollar estates with expansive views to more intimate cottages, all benefiting from the island's limited supply and ROGO-exempt status in some cases. The market emphasizes custom builds and renovations that complement the tropical aesthetic.
Nearby attractions include the historic sites, galleries, and nightlife of Key West's Old Town, accessible in minutes by ferry. Residents can easily enjoy the island's calm during the day and transition to the mainland's cultural offerings at night.
Parks and recreation center on the island's private beaches, tennis facilities, and fitness options, with green spaces and waterfront areas enhancing the natural setting.
Shopping and dining are highlighted by on-island options like the gourmet Latitudes restaurant, supplemented by the full array of Key West's renowned eateries, boutiques, and markets just across the water.
Transportation relies on the dedicated ferry system, which handles residents, guests, deliveries, and even groceries, eliminating the need for on-island vehicles and supporting a car-free environment.
Demographics reflect a mix of full-time residents and seasonal homeowners drawn to the luxury private-island market, though specific census data is limited due to the community's scale.
Safety and livability are bolstered by patrolled areas, a central fire station on the island, and coordinated emergency protocols, contributing to a secure and serene environment.
Local highlights include the unique hybrid model of residential governance paired with resort amenities, the private white-sand beaches, and the seamless blend of seclusion with urban proximity.
People choose Sunset Key for its unparalleled privacy, the convenience of ferry access to Key West, the resort-style services that simplify daily life, and the opportunity to own a piece of one of Florida's most distinctive island communities. The combination of natural beauty, exclusive amenities, and thoughtful infrastructure creates a lifestyle that appeals to those seeking both tranquility and connection.
