East Sister Rock Island, a miniature private island and dream getaway that doubles as a thriving vacation rental, is on the market for $16,499,999, offering one lucky buyer the rare opportunity to own a secluded retreat in the Florida Keys.
This 1.4-acre island is a mere quarter-mile from Marathon, Florida, and is accessible only by boat or helicopter, providing a level of privacy and exclusivity unmatched by mainland properties.
The island’s history is as unique as its location.
Built in the 1970s, before the implementation of stricter environmental laws, the island was created for a New Jersey gastroenterologist, Klaus Meckler.
Its structure, a concrete home resting on 75 pillars drilled into coral rock and elevated on a 15-foot high plateau, showcases both engineering ingenuity and a deep respect for the surrounding natural beauty.
The 2,304-square-foot main residence, complemented by a detached guest house, features three bedrooms and two bathrooms — and has been operating as a popular vacation rental in recent years, with stellar reviews from travelers.
The property’s eco-friendly design includes a solar and wind power system, a 15,000-gallon freshwater cistern, and its own desalination plant. This off-grid setup ensures a self-sufficient living experience that aligns with modern sustainability values.
Notable for its luxurious amenities, East Sister Rock Island boasts an outdoor pool, a helicopter pad, and a dock, catering to various modes of transportation and leisure activities.
The island’s location on a coral reef, surrounded by protective rocks, offers stunning 360-degree ocean views and a serene environment, perfect for relaxation and outdoor entertainment.
In addition to its private use, the island has also been operating successfully as a vacation rental.
Guests have consistently rated their stays as exceptional, highlighting the island’s tranquility, convenience, and unique experience of seclusion close to necessary amenities.
Reviews praise the comfort of the property and its amazing location, noting its easy access to nearby attractions and the fantastic fishing opportunities it offers.
This property was nothing short of amazing! My wife and I had dreamed of doing a trip like this since we’ve been married, due to the season we were in when we tied the knot a honeymoon just wasn’t in the cards. 9 years later we arrived on East Sister Rock, and enjoyed this incredible home with our family. The home was well kept, the bathrooms were gorgeous, and the home is nothing short of captivating.One VRBO review reads
