St. Croix is 84 square miles in size, 22 miles long and the widest point is a little more than 6 miles, about 82 sq miles. The island is 1700 miles south of New York, 1100 miles SE of Miami, on the same latitude as Hawaii and Acapulco, with a population of about 55,000.

St. Croix, the largest of the U.S. Virgin Islands, is approximately 28 miles long and 7 miles wide at its broadest points. In 2026, it remains a diverse "Twin City" island, with the historic town of Christiansted on the east and Frederiksted on the west. Covering roughly 84 square miles, its terrain varies significantly: the west end features a lush subtropical rainforest, while the east end is characterized by a dry, desert-like landscape with cacti and rocky coastlines. Because of its elongated shape, driving from one end of the island to the other takes about 45 to 60 minutes via the Melvin Evans Highway, depending on local traffic. Despite its relatively small mileage, the island’s varied topography—including Mount Eagle, which rises to 1,165 feet—makes it feel much larger than its neighbors, St. Thomas and St. John, and provides ample space for both industrial zones and pristine national parks.
