About Key Biscayne

Key Biscayne is a barrier island community just a bridge ride from Brickell, offering an island lifestyle wrapped around Crandon Park, Cape Florida State Park, and the Crandon Golf Course. The village is known for its safety, top-rated schools, and walkable pace, with residents ranging from young families to international buyers seeking secondary residences. Limited inventory and tight geography keep prices premium relative to mainland Miami.
