About
Separated from the mainland by Biscayne Bay yet just minutes from downtown, Key Biscayne delivers a rare combination of seclusion and convenience that few Miami addresses can match. Crandon and Bill Baggs state parks preserve two stretches of undeveloped coastline at either end of the island, and Crandon Park hosts professional tennis. The waters surrounding the island rank among the clearest in South Florida. A compact village center of low-rise shops, a single causeway in and out, luxury estates on the interior streets, and oceanfront condo lines along the beach define an island that stays quiet without leaving the city.

Frequently Asked Questions
Common questions about buying and investing in this area
What is Key Biscayne known for?
Reached by the Rickenbacker Causeway, Key Biscayne is an exclusive island community whose reputation rests on Crandon Park beach — perennially ranked among the country's finest — Bill Baggs Cape Florida State Park with its storied lighthouse, and a deeply private residential enclave that has long drawn celebrities and senior executives.
How much does real estate cost in Key Biscayne?
Scarce supply and island exclusivity hold Key Biscayne firmly in the top tier of Miami real estate. Condos range from $500,000 to $15 million and beyond, single-family homes start at $2 million, oceanfront estates can top $50 million, and the overall median lands around $2-3 million.
How much of Key Biscayne is parkland?
For buyers who put privacy and access to nature first, Key Biscayne is tough to beat. The beaches stay immaculate, the parks are extensive, and the community is genuinely close-knit. Strict development rules cap density and preserve the island's residential character.
What is the lifestyle like on Key Biscayne?
Island life here rolls out at a leisurely resort pace, framed by stunning beaches, world-class tennis facilities at Crandon Park, dedicated cycling paths, and a full slate of outdoor recreation. The Village center supplies local shops and restaurants, and a sizeable share of residents spends weekends sailing, fishing, and enjoying water sports.
What are the drawbacks of living on Key Biscayne?
The island's remoteness cuts both ways: dining and nightlife stay modest next to mainland Miami, and Rickenbacker Causeway traffic can back up badly at peak hours while toll costs add up over time. Hurricane evacuation orders are mandatory for island residents, flood insurance premiums run meaningful, and tight development controls mean very little new construction ever reaches the market.
