Isle a Quatre is an exceptional 376-acre uninhabited island located in the heart of the Grenadines. Positioned just one and a half miles south of Bequia and five miles west of Mustique, this freehold property offers a rare blank canvas in one of the Caribbean's most exclusive maritime corridors. Historically settled by the French, the island is now poised for a low-impact, high-quality transformation, supported by specific government incentives designed to facilitate the creation of a premier private retreat or luxury resort.
Property Details
The island is currently untouched, save for the ruins of an old estate house and a basic cart road. It is sold with a master plan that envisions a low-density development model similar to Mustique. Potential exists for a boutique hotel, a marina, and up to 45 private villa plots. The "Quatre Isle Resort Act" provides a legislative framework for the island's future, offering substantial benefits such as a 20-year tax holiday and residency eligibility for owners and investors.
Land and Water
The topography is defined by rolling hills that rise to 479 feet (146 meters), providing 360-degree views of the archipelago. The coastline spans nearly 6 miles (9.85 km) and features five protected west-facing bays and four distinct white-sand beaches. The surrounding waters are rich in coral reefs, making it a prime location for snorkeling and diving. The interior is covered in subtropical vegetation, with mature trees concentrated near the eastern and southern shores.

Access and Utilities
Proximity to Bequia’s airstrip ensures convenient regional access, while the island's deep-water bays support the development of marine transport infrastructure. The island is currently off-grid; however, engineering studies for essential infrastructure—including water desalination, electricity, and waste disposal—have been commissioned to support future development.
Lifestyle and Value
Isle a Quatre offers the ultimate foundation for a legacy asset. Its scale allows for complete privacy and conservation-minded planning, while its location places it within sight of the region's most celebrated luxury destinations. Whether developed as a commercial ultra-luxury resort or a private family kingdom, the property combines the exclusivity of a private island with the security of government-backed investment incentives.
