Key Biscayne Miami is the city’s island escape — a 1.5-mile barrier island just 7 miles from downtown but a world apart from South Beach’s intensity. Linked to the mainland by the Rickenbacker Causeway, the island holds two of Miami’s most beautiful parks (Crandon and Bill Baggs Cape Florida), the historic Cape Florida Lighthouse, the Ritz-Carlton’s flagship resort, and a small village center that feels more Cayman than Miami. This guide covers everything you need to know about Key Biscayne Miami — beaches, things to do, where to stay, where to eat, and how to make the most of a half-day or full-week visit.
