Sunset Key is a small private island just offshore from Key West in the Florida Keys, offering a quieter setting surrounded by the Gulf of Mexico. The island is centered on residential properties and the Sunset Key Cottages resort, with white-sand beaches, palm trees and low-rise buildings arranged along brick-paved paths. Access is by boat from Key West, giving the island a distinct separation from the busy streets of the city. Its compact size and waterfront setting make Sunset Key notably different from the larger, more developed areas of Key West.
Sunset Key also has an unusual connection to the area's military and maritime history. The island was created as an artificial landmass and was originally known as Tank Island. It was intended for use as a naval fuel storage site, although the planned facility was never fully developed. Today, little of that industrial purpose is visible in the island's resort and residential landscape. Its modern identity is instead associated with private homes, guest cottages, boat access and the wider traditions of Key West, where fishing, sailing and life on the water remain important.
The island's main attractions are its coastal surroundings and peaceful outdoor setting. Its sandy beach faces the Gulf, while the shoreline provides views toward Key West and the surrounding waters. Guests can swim, relax on the beach, use the tropical pool or explore the island on foot. Sunset Key also has a marina with facilities for visiting boats, and the surrounding Florida Keys waters provide opportunities for snorkeling, fishing and sailing. The island's proximity to Key West means that historic streets, museums and other attractions remain accessible by boat.
Dining is centered on Latitudes, the island's waterfront restaurant, which serves seafood and other island-inspired dishes in an open-air setting overlooking the water. Sunset Key is also known for its regular boat service connecting the island with Key West, an important part of daily life for residents and guests because there is no road connection. One of its lesser-known details is that its landscaped, resort-like appearance conceals a very different past as a proposed naval fuel facility. The contrast between that industrial history and its present-day coastal setting gives Sunset Key a distinctive identity within the Florida Keys.
