St. Croix provides gorgeous beaches, world-class recreational activities, fine dining, casino, and golf.

Visiting just the two main towns of Saint Croix will give you a glimpse of the island’s incredible history—from regal 18th and 19th-century homes in Christiansted to a tropical rain forest in Frederiksted.
