Buck Island Reef National Monument, located off the northeast coast of St. Croix in the U.S. Virgin Islands, is a tropical paradise that beckons discerning travelers with its unparalleled marine beauty. This 19,015-acre sanctuary, established by President John F. Kennedy in 1961 and expanded in 2001, protects one of the Caribbean’s most exquisite marine gardens.
The monument encompasses a 176-acre island and an extensive 18,839 acres of submerged land, dominated by a vibrant elkhorn coral barrier reef. This reef, two-thirds of which surrounds the island, is a snorkeler’s and scuba diver’s dream, with its intricate coral formations, deep grottoes, and abundance of reef fishes, sea fans, and gorgonians. The eastern tip features a marked underwater trail, one of only three in the United States, where visitors can follow interpretive signs through coral grottoes.
On land, the island boasts white coral sand beaches, including the celebrated Turtle Beach, voted one of the world’s most beautiful by National Geographic. Here, endangered leatherback, green, and hawksbill turtles come to nest, witnessed by lucky visitors during the spring and summer months. The island’s overland nature trail offers a chance to explore the tropical dry forest, replete with native flora and fauna, and enjoy a bird’s-eye view of the reef below.
Visitors can opt for guided tours with authorized concessioners or obtain permits for private vessels to ensure a respectful and safe experience. To protect the delicate ecosystem, non-toxic reef-safe sunscreen and rash guards are recommended.
Each year, around 50,000 visitors are drawn to this protected haven, which is also a critical nesting site for brown pelicans and least terns. The National Park Service’s long-standing research programs here focus on coral, fish, sea turtles, and other marine life, ensuring the ecosystem’s continued health.
For those seeking an immersive experience, daily trips to the monument offer a mix of leisurely swims, snorkeling, and hiking, all set against the backdrop of crystal-clear waters and a rich tapestry of marine and terrestrial life. Buck Island Reef National Monument is a must-visit for any traveler eager to explore the unspoiled beauty of the Caribbean.
