Private Island Estates for Sale on the Sunset Islands, Miami Beach, Florida

The Sunset Islands are Miami Beach’s most family-oriented private island community — four small manmade islands (Sunset Island I, II, III, and IV) in Biscayne Bay’s northwest section, accessible via the Sunset Harbor neighborhood and a gated causeway, where the residential character tends toward long-term families and established professionals rather than the celebrity-concentrated ownership profile of Star Island or Indian Creek. The islands’ approximately 200 combined residential lots provide a range of price points within the private island category, with bay-front positions on the outer islands commanding the market’s upper tier. Estates range from $3M to $20M+. Giant Mansions provides full representation across all four Sunset Islands.

Luxury Real Estate on the Sunset Islands, Miami Beach, Florida

The Sunset Islands are four manmade islands in the northwest section of Biscayne Bay, accessible via the 28th Street bridge from Miami Beach’s Sunset Harbor neighborhood. The four islands — numbered I through IV — have slightly different characters: Islands I and II front Biscayne Bay directly with the most significant bay views and dock capacity; Islands III and IV are positioned more interiorly with canal and waterway frontage. Together the four islands contain approximately 200 residential lots across a range of sizes and orientations.

The Four Islands and Their Distinctions

Sunset Island I and II occupy the outer positions with direct Biscayne Bay frontage and the longest sight lines across the bay toward Miami’s skyline. Sunset Island III and IV are set back from the open bay with more protected waterway positions — calmer dock conditions, somewhat more modest views, and generally more accessible price points. The community across all four islands shares gated access from the mainland bridge and a residential character defined by long-term family ownership rather than celebrity profile.

Sunset Islands Estate Categories

• Sunset Island I and II bay-front estates with open Biscayne Bay views — $8M to $20M+
• Sunset Island III and IV waterway-front properties with protected dock positions — $3M to $10M+
• Interior island estates with community access and neighborhood character
• Renovated and new construction estates across all four islands

Sunset Islands in the Miami Beach Context

The Sunset Islands’ proximity to the Sunset Harbor neighborhood — one of Miami Beach’s most pedestrian-friendly and independent-restaurant-concentrated commercial districts — gives residents walkable access to a quality dining and shopping environment that the more isolated Star and Palm Islands cannot match. The Wynwood Arts District and Midtown Miami are accessible in minutes via the Julia Tuttle Causeway north.
