The National Marine Sanctuary of American Samoa is in the heart of Polynesia's oldest culture. It protects large coral reefs, including some of the oldest and biggest Porites corals globally, as well as deep-water reefs, hydrothermal vents, and unique marine archaeological sites.
About Our Sanctuary
The National Marine Sanctuary of American Samoa stands as one of the 14 federally designated underwater areas that are meticulously protected by NOAA's Office of National Marine Sanctuaries. Among all the diverse areas in the National Marine Sanctuary System, the American Samoa sanctuary is recognized as the most remote and isolated, yet it supports an extraordinary variety of marine life and ecosystems. This remarkable sanctuary is comprised of six protected areas that collectively cover a vast expanse of 13,581 square miles, including both nearshore coral reefs and the expansive offshore open ocean waters that span across the stunning Samoa Archipelago.
Out of these six protected areas, three are situated on and near Tutuila, making them relatively accessible for visitors. Fagatele Bay and Fagalua/Fogama'a are located along the picturesque southwest coast of Tutuila Island, while Aunu'u Island is conveniently positioned just southeast of Pago Pago Harbor. The remaining areas are more remote and can only be accessed by boat, emphasizing the need for proper planning.
