St. Croix is the largest island in the U.S. Virgin Islands group and is significantly more rural than St. Thomas. The island features two historic towns, a rain forest in the western interior, an arid climate in the east end and spectacular coral formations that are accessible from many beaches.
The island was a possession of Denmark until the early nineteenth century and boasts a deepwater port in the west-end town of Frederiksted. The port was defended by Fort Frederik as far back as the mid eighteenth century. The island, along with St. Thomas and St. John, was bought by the United States in the early nineteenth century. That means you don’t need a passport to visit and, best of all, you can bring five liters of liquor back to the United States duty free.
