Overview
Key Biscayne is a village of roughly 14,000 residents on a barrier island between Biscayne Bay and the Atlantic Ocean. Connected to the mainland by the Rickenbacker Causeway (toll bridge), it offers Crandon Park (public beach and tennis center), Bill Baggs Cape Florida State Park, and the historic Cape Florida Lighthouse. The island has a distinct small-town feel with its own village council, police, and schools.
Lifestyle
Beach days at Crandon Park, cycling the island loop, tennis at Crandon Park Tennis Center (former home of the Miami Open), kayaking in Biscayne Bay, and dining at the Ritz-Carlton Key Biscayne. The village has a strong community calendar with farmers markets, holiday events, and 4th of July celebrations that feel more like a small town than Miami.

Frequently Asked Questions
Is Key Biscayne safe?
Key Biscayne is one of the safest communities in Miami-Dade County. The single-access Rickenbacker Causeway creates a natural barrier, and the village has its own police department with a strong community presence. Crime rates are significantly below Miami-Dade averages. The island's small size and tight-knit community contribute to a strong sense of security.
What are the cons of living on Key Biscayne?
The Rickenbacker Causeway is the only road on and off the island, creating traffic bottlenecks during rush hour and hurricane evacuations. The causeway toll adds up ($1.75 each way or $1 with SunPass). Dining and shopping options are limited compared to mainland Miami — most residents drive to Brickell or Coral Gables for variety. Insurance costs are higher due to the barrier island location.
How is the real estate market on Key Biscayne?
Key Biscayne is a supply-constrained market — the island is fully built out with no room for new development beyond replacing existing structures. This scarcity supports strong pricing. The market is roughly split between condos (Ocean Club, Grand Bay, Ritz-Carlton) and single-family homes. Waterfront homes with bay or ocean access command the highest premiums. International buyers, particularly from Latin America, remain active.
