National Park of American Samoa is located some 2,600 miles southwest of Hawaii and is one of the most remote in the U.S. National Park System. The site includes sections of three islands—Tutuila, Ta’ū, and Ofu. Almost all of the land area of these volcanic islands—from the mountaintops to the coast—is tropical rainforest. The park’s area totals 13,500 acres, 4,000 of which are underwater.
