Key Biscayne, the island Miami keeps for itself

An island village south of the city, between award-winning beaches and the historic lighthouse.

The region

Paradise minutes from downtown

Key Biscayne is an island village south of Miami, linked to the mainland by the Rickenbacker Causeway. Here, everyday life moves at a beach-village pace: bike paths, marinas, tennis and a community that chose the island as a lifestyle.

The island's beaches rank among Florida's most beautiful — from Crandon Park to Bill Baggs Cape Florida State Park, with its historic lighthouse. It is a setting that feels far from everything, minutes from the financial center.

The island's luxury market blends waterfront estates of rare scale — like 485 W Matheson Dr, President Nixon's former 'Winter White House' — with sophisticated condos facing the bay or the sea. Rarity and privacy set the prices.
