A private island in the Florida Keys, featuring a helipad and extensive waterfront, is once again available for $16 million. Located a quarter-mile off the coast of Marathon, Florida, the property provides a blend of seclusion and accessibility, being reachable only by boat or air while remaining minutes from mainland conveniences.

The estate includes a three-bedroom main residence and a separate one-bedroom guesthouse, totaling approximately 5,000 square feet of living space. The primary home, recently renovated, boasts a new kitchen. The property is entirely off-grid, powered by its own solar and wind energy systems, offering self-sufficiency.

Beyond the structures, the island encompasses 5.8 acres of surrounding seabed, creating a private underwater area suitable for activities like snorkeling and lobstering. The Atlantic Ocean side location offers distinct advantages over Gulf-side properties, according to co-listing agent Vladimir Rochebrun of The Chad Carroll Group at Compass, citing fewer environmental nuisances.

Access is facilitated by a private helipad and a substantial dock capable of accommodating large boats. Residents can reach the mainland within minutes, where parking is available, and essential services like grocery stores are a short drive away. The listing agents highlight the property's appeal to those seeking privacy without complete isolation.

Vladimir Rochebrun and Aaron Rosenthal of The Chad Carroll Group at Compass are co-listing the property. Rochebrun noted that the island has historically served as both a family retreat and a successful investment property, generating income through rentals. Rental rates have ranged from $13,500 weekly to $17,500 for holidays.

The island offers various recreational opportunities, including swimming, kayaking, paddleboarding, fishing, and snorkeling. A protected snorkeling area and a fishing pier are among the amenities. The property was last listed in 2021 for $11.7 million.
