History
Connected to the Miami mainland by the 3.6‑mile Rickenbacker Causeway, Key Biscayne is an island where nature sets the pace, and at its heart lies The Ritz-Carlton Key Biscayne, Miami. Following a $100 million renovation completed in late 2025, the 421-room resort has reemerged as a sun-washed tropical escape that is calmer, lighter, and more aligned with how people want to vacation now. A soaring, light-filled lobby frames the Atlantic through triple-story glass, while the revived Rum Bar anchors a space that stays lively without feeling crowded.
Couples, families, and longtime loyalists move easily through the property, to and from refreshed guest rooms and suites finished in a restrained coastal palette of strawberry-blonde woods, warm gold fixtures, and floor-to-ceiling glass that keeps attention on sea and sky. Days pass between the new, 30,000-square-foot Ritz-Carlton Spa, Key Biscayne, intentionally set apart from the resort's social energy; the restaurant Luma, where you can dine on Italian-driven plates; and Dune Beach Bar for relaxed, toes-in-the-sand afternoons. Nature is a constant presence, from the protected waters surrounding the island to the open lawns and oceanfront spaces that define the resort experience. Families are well accounted for, with expansive pool areas, Ritz Kids Club programming, and clear separation between adult and family zones. Taken as a whole, the reimagined Ritz-Carlton Key Biscayne is the rare Miami-area property where staying put is exactly the point.
