Seasoned sailors know the island of Grenada well. Set on the southern end of the Caribbean cluster, just northeast of Venezuela, the well-positioned island has long held an allure for yacht owners, despite (or perhaps because of ) its lack of upscale options on land. As of this month, however, there’s finally a reason to disembark—and maybe even set down roots: Silversands Grenada (silversandsgrenada.com), the island’s first true luxury resort, opened December 1 with 43 suites on the edge of Grand Anse Beach. The creation of Egyptian billionaire Naguib Sawiris—who makes his own regular pilgrimages to the island via his superyacht Yalla— the property is sleek and sexy with just the right amount of excess, including a palm-treelined swimming pool as long as a football field, a beach club, and a rum bar with a stash of rare Cubans. What makes it a true billionaire’s oasis, though, are its nine residences (priced from $5.7 million to $11 million), each with multiple private swimming pools and ample space for entertaining.
