About Bahia Mar

Estates

Bahia Mar Estates, located between U.S. 1 and Florida Bay, is a canal-front and low-density Key Largo neighborhood with private docks and a salt-air, boating-first rhythm. The neighborhood’s character concentrates around the U.S. 1 corridor near Caribbean Club, where tiki-lit patios, marina traffic, and sunset chatter set the tone. Architecture leans to elevated Keys cottages and concrete-block homes built for breezes and water views. Days revolve around skiffs in the canals, kayaks on the bay, and quick runs to the reef. Community touchstones include the Caribbean Club, Jimmy Johnson’s Big Chill, and the Florida Keys History & Discovery Center.
