Key Colony Beach combines a public city beach with direct access to the Gulf of Mexico and the Atlantic Ocean. For planning, it helps to distinguish this coastal perspective from specific activities: Sunset Beach is on the western shoreline, while the snorkeling and wreck sites mentioned are offshore. The area’s history also spans its earlier name, Shelter Key, the island’s formation in the early 1950s, and events in 1958. This lets you consider beach time, a possible trip on the water, and local events as separate parts of your stay.
Beach and Coast
Sunset Beach is on the western shoreline; a 2020 state coastal management description identifies it as a public city beach. Check current beach conditions locally before your visit. The same description lists a 0.9-mile critically eroded stretch of beach in Key Colony Beach along the Florida Strait. This classification applies to the stretch mentioned and does not describe every coastal area in the city. The shoreline is also stabilized by 15 limestone groins built in 1958.
Snorkeling and Wreck Diving
The Coffins Patch Sanctuary Preservation Area is about four and a half miles offshore from Key Colony Beach; snorkeling opportunities are available in the Middle Keys area. Sea conditions and protected-area rules can change. The Rib Wreck is about half a mile southwest of Key Colony Beach, at an average depth of 14 feet. The Thunderbolt is four miles south of Marathon and Key Colony Beach, at a depth of 120 feet. The figures clearly distinguish the wrecks by depth: the Rib Wreck averages 14 feet, while the Thunderbolt is listed at 120 feet. For both, access depends on sea conditions and arrangements with an operator. For planning, you can first choose between snorkeling in the protected area and wreck diving, then take the relevant conditions into account.
The Island’s Formation
Key Colony Beach developed from Shelter Key, which originally covered more than 97 acres. A dredging and fill project that began in the early 1950s resulted in an island of nearly 400 acres. The building now used as City Hall also has a dated history: in 1958, its auditorium hosted a meeting of the Outdoor Writers of America Association, attended by about 800 writers. The Key Colony Beach Sailfish Tournament also began in 1958. About 60 sport anglers took part in its inaugural event.
Activities and Events
Key Colony Beach’s 9-hole par-3 golf course is on 8th Street. Sunset Park is a quiet spot for wedding ceremonies overlooking the ocean. Key Colony Beach Day is the city’s birthday celebration and takes place in March. The Key Colony Beach Market is a seasonal market held on Tuesdays. These details offer different points of reference for planning your trip: a month for the city celebration, and a season and day of the week for the market. Since event dates and seasonal market hours can change, check the specific dates before you travel.
