1. Lanai, Hawaii – The $300 Million Paradise Estate
Purchased by Oracle co-founder Larry Ellison for an estimated $300 million, Lanai in Hawaii is more than just a home; it's a living laboratory. Ellison owns 98% of the island’s 90,000 acres and has invested hundreds of millions more to transform it into a model of sustainability.

2. Indian Creek Island, Miami – Billionaire Waterfront Mansions
Known as the "Billionaire Bunker," Indian Creek Island in Miami is one of the most exclusive and secure neighborhoods in the United States. With only 41 homes, this island fortress is a magnet for the ultra-elite, including figures like Jeff Bezos and Tom Brady. The island's appeal is less about beachfront views and more about absolute confidentiality and protection, making it one of the priciest home markets on any US island.
The emphasis here is on controlled access and a life removed from the public eye. Security is paramount, and the entire island is designed to ensure the utmost privacy for its high-profile residents. Key features that enhance this exclusive lifestyle include:
- A private, members-only golf club.
- A dedicated police force for the island's 41 waterfront estates.
In 2025, a vacant plot sold for a record-breaking $105 million, highlighting that on Indian Creek Island, silence and solitude are the most valuable commodities. It's a true fortress of net worth.
3. Tarpon Island, Palm Beach – Ultra-Luxury Wellness Retreat
Redefining exclusivity in Palm Beach, Tarpon Island was acquired in 2024 for around $150 million. This man-made island is accessible only by a private bridge and was designed for the modern billionaire. The property is a turnkey private island experience, blending old-world glamour with contemporary demands for self-sufficient living.
This estate is a fortress of comfort, featuring a 28,600-square-foot mansion designed for both work and relaxation. The focus is on a seamless blend of security, wellness, and privacy. Its amenities include:
- An expansive wellness wing for health and fitness.
- A lighted tennis court and multiple docks for yachts.
With its home offices and quarantine-proof layout, Tarpon Island exemplifies the post-pandemic desire for a secure and luxurious wellness retreat. The price point is comparable to top-tier properties in the Caribbean, showing a similar range for ultra-luxury island homes in the US.
4. Musha Cay, Bahamas – David Copperfield’s Magical Hideaway
Owned by famed illusionist David Copperfield, Musha Cay in the Bahamas is one of the most exclusive private resorts in the world. Purchased for $150 million, this magical hideaway in the Exumas is more than just a property; it's a stage for unforgettable experiences. The island and its surrounding islets span over 700 acres, offering a truly private escape.
This island paradise hosts just 24 guests at a time, with nightly rates exceeding $50,000. What makes Musha Cay one of the most expensive private islands is not just its land value but the bespoke entertainment it offers. Its unique attractions include:
- Custom-themed treasure hunts created by Copperfield's team.
- Private concerts and spectacular fireworks displays on the beach.
Copperfield himself calls it "the most magical place on Earth." For those who can afford it, Musha Cay provides a level of customized luxury and entertainment that is unmatched, making its original purchase price one of the highest for a home in the Caribbean islands.
5. Skorpios, Greece – The Legendary Onassis Villa
The legendary Greek island of Skorpios, once the private playground of shipping magnate Aristotle Onassis, carries a rich history. In 2013, it was acquired for approximately $153 million by Ekaterina Rybolovleva. Today, the island is being transformed into an ultra-exclusive wellness retreat, blending its glamorous past with modern sustainability.
Development is carefully managed, with construction permitted on only 5% of the freehold land to preserve its natural Mediterranean beauty. This approach creates a unique blend of luxury and conscientious living. Features of the revitalized Skorpios include:
- A small, exclusive collection of villas for guests.
- Spa facilities and organic farms set against the stunning Ionian Sea.
With its high acquisition cost, Skorpios is a top contender for one of the highest-priced private island sales. The island stands as a modern-day Olympus, where the legacy of the Onassis era meets a new vision of mindful luxury.
6. Bell Island, Bahamas – The Philanthropist’s Private Escape
Purchased in 2009 by the Aga Khan IV for an estimated $100 million, Bell Island in the Exumas serves as a personal haven rather than a commercial enterprise. This 349-acre private escape is designed for serenity and seclusion, surrounded by protected marine parks and pristine ecosystems in the Bahamas.
The island is a testament to the owner's commitment to conservation. After acquiring the property, the Aga Khan donated $1 million to the Bahamas National Trust, the organization responsible for managing the surrounding environment. The island’s infrastructure is built for discreet luxury and includes:
- Two main residences and beautifully designed guest cottages.
- A private heliport for convenient and private access.
Bell Island demonstrates how the world's most expensive islands can be more than just assets; they can also represent a commitment to philanthropy and environmental preservation, offering a deeply personal and private escape.
7. Vatuvara Private Islands, Fiji – Secluded Eco-Exclusivity Homes
Valued at an estimated $155 million, the Vatuvara island group in Fiji represents one of the most untouched and exclusive properties on the market. This portfolio of islands spans over 4,000 acres, offering a model of conservation-led development and true seclusion. The main island features dense jungles, dramatic limestone cliffs, and vibrant coral reefs.
Freehold land is exceptionally rare in Fiji, making this collection of islands an even more valuable investment. The property includes a small eco-resort that operates entirely off-grid, emphasizing sustainability and a minimal environmental footprint. Its natural assets include:
- Over 1,200 acres of pristine land on the main island.
- Access to protected coral reefs and thriving marine ecosystems.
For those seeking absolute privacy with a focus on eco-exclusivity, Vatuvara is an unparalleled destination. Its significant valuation places it among the most expensive private islands available right now, catering to buyers who prioritize sustainability.
8. Cayo Norte, Puerto Rico – Nature-Preserved Luxury Residences
While some billionaires build lavish resorts, others choose to preserve nature. Google co-founder Larry Page purchased the 300-acre Cayo Norte in Puerto Rico for $32 million in 2018 with a different vision in mind. Instead of developing luxury residences, the island remains a largely untouched sanctuary.
The value of Cayo Norte lies in what it lacks: concrete, marinas, and large-scale construction. Its pristine beaches are nesting grounds for sea turtles, and its forests are free from development. This nature-preserved approach shows that true luxury can mean leaving a place as you found it. The island's key natural features are:
- Untouched forests and pristine, undeveloped beaches.
- Surrounding coral reefs teeming with marine life.
Page's strategy highlights a different philosophy of island ownership—one focused on conservation and personal refuge rather than commercial return.
9. The World Islands, Dubai – Middle East’s Record-Breaking Villas
While many of the world's priciest islands are natural, Dubai has engineered its own solution: The World Islands. This man-made archipelago off the coast of the UAE replicates the world map with over 300 islands, offering a new kind of island living. These record-breaking villas provide Middle Eastern buyers with island exclusivity close to home.
Projects like The Heart of Europe feature premium villas on private islands, with prices quoted at over AED 100 million. They are designed as self-sufficient luxury resorts combining architectural ambition with unparalleled exclusivity. The cost of these engineered islands shows how prices differ between regions, with Dubai competing at the highest level. Key details of The World Islands include:
- Location — Man-made archipelago 4 km off the coast of Dubai
- Price Point — Villas starting from AED 100 million (approx. $27.2 million)
- Unique Amenities — Underwater bedrooms, private beach access, infinity pools
- Concept — Over 300 islands shaped into a world map
This project underscores how Dubai is redefining island luxury by offering incredible accessibility and a level of engineered extravagance that rivals traditional island paradises.
10. Necker Island, British Virgin Islands – Sir Richard Branson’s Iconic Estate
