Occupying a significant portion of the picturesque archipelago, the Culebra National Wildlife Refuge is a true gem of the Caribbean. Located in the town of Culebra within Puerto Rico, this protected area covers approximately 5.86 km² of pristine land, including the island itself and numerous surrounding small cays.

This refuge is rightfully considered one of the most important centers of biodiversity in the region. Its landscapes are strikingly diverse, ranging from subtropical dry forests to mangroves and secluded lagoons. The primary value of this place lies in preserving the natural habitat for many species of birds and marine life, making it a must-visit destination for ecotourism enthusiasts.
The reserve gained particular fame as a key nesting site for massive populations of seabirds, specifically sooty terns. Thanks to its status as one of the oldest natural sanctuaries under the U.S. Fish and Wildlife Service, it has managed to preserve a unique ecosystem and beaches of incredible beauty that remain untouched by mass development.
