Welcome to Key Colony Beach

A compact island city built around boating, beaches and an easygoing neighborhood lifestyle

Key Colony Beach is a small, incorporated island city just off Marathon, connected to the Overseas Highway by a short causeway. Often called the Gem of the Florida Keys, it is known for wide canals, excellent boating access, waterfront homes and half-duplexes, oceanfront condominiums and a rare sense of walkable community. Residents and visitors can bike or stroll to restaurants, Sunset Park, pickleball and tennis courts, a par-three golf course and private beach-club amenities. Its blend of neighborhood charm, vacation appeal and convenient access to Marathon makes Key Colony Beach one of the most distinctive residential markets in the Middle Keys.

LOCAL DETAIL

The island was developed from low-lying land in the 1950s and incorporated in 1957. Its numbered streets, canals and compact layout make it unusually easy to navigate by bicycle, golf cart, boat or on foot.

ON THE WATER

Boaters have quick Atlantic access through Vaca Cut and nearby channels. The Grassy Key or Valhalla Sandbar is a popular regional outing, while Coffins Patch and Sombrero Reef are nearby snorkeling and diving destinations rather than sandbars.

WHERE TO EAT

Key Colony Inn for classic Keys dining; Havana Jack's for oceanside food, drinks and live music; and Sparky's Landing, just across the causeway in Marathon, for a lively marina atmosphere.

NOTABLE NEIGHBORHOODS & COMMUNITIES

The numbered canal streets from 1st through 15th; Shelter Bay; East and West Ocean Drive condominium communities; and the waterfront homes around Sadowski Causeway and the island's eastern end.
