Buck Island Reef National Monument, St. Croix

Explore the protected barrier reef at Buck Island Reef National Monument, a small island reserve around 2.4 km (1.5 mi) north of Saint Croix. The naturally abundant island and surrounding waters--3.6 sq km (1.4 sq mi) total--have enjoyed protection under U.S. law since 1961. An elkhorn coral barrier reef surrounds a large portion of the island, creating an ecosystem for a large variety of fish, reef sharks, and rays. Snorkel around the reef, following an underwater trail signposting the natural inhabitants of each section. Back on dry land, rest up on one of the pristine beaches and take a stroll along the main walking routes.
