The best view is from the air. But when you touch down, the excitement only builds. Spread out before you is a Caribbean spectacle to take your breath away. Here, on this slender island near Marathon, surrounded by coral reefs dazzling under puffy white clouds, a marriage takes place—of American security, total privacy, and being able to control the largest privately held lands in the Florida Keys. Master-minded by an American land baron who first spotted the gem from his plane and then transformed it into his family compound, Sunset Point, with its 4,000 feet of waterfront and everything from a four-bedroom poolside villa with coconut palms and dock to a saltwater lagoon and grassy helipad, remains one of the world’s grandest tropical getaways—a magical synergy of man and nature.
