Little Hall's Pond Cay, Bahamas
Surrounded by crystal clear Bahamian waters, this 45-acre (18.2-hectare) paradise was purchased by actor Johnny Depp for $3.6 million in 2004 [source: Private Islands]. In addition to its rich and exotic plant, animal and marine life, Little Hall's Pond Cay features six beautiful white-sand beaches and several modest, solar-powered residences [source: Brinkley].
The island is one of more than a dozen cays that fall within the boundaries of the Exuma Cays Land and Sea Park, a "no-take" zone about 65 miles (104 kilometers) southeast of the capital city of Nassau [source: The Nature Conservancy]. Its location within the park -- the oldest in the Bahamas -- means that Depp's private getaway is forever protected from fishing or other marine harvesting or development.
Little Hall's Pond Cay itself is, of course, off-limits to the public, but fortunately for the rest of us, sailing, swimming, snorkeling, diving and hiking are permitted on and around many of the pristine public cays in Exuma Park [source: The Nature Conservancy].
