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.

Within the sanctuary, you will discover deep water reefs, hydrothermal vents, and some of the world's oldest and largest Porites coral heads. Additionally, it is home to rare archaeological resources and encompasses important fishing grounds that are vital to the local community. Notably, this sanctuary is also distinguished as the only true tropical reef within the entire National Marine Sanctuary System.

Visitors are highly encouraged to explore the easily accessible areas on Tutuila, where they can engage in various activities such as hiking, swimming, and discovering the magnificent reefs that lie within the sanctuary. While the more remote areas are open to the public, they require a reliable vessel and an experienced captain to ensure safe access. These unique areas play a significant role in scientific research and in the protection of invaluable natural and cultural resources.
