Introduction
The National Park of American Samoa protects tropical rainforest, coral reefs, volcanic mountains, beaches, and Samoan cultural landscapes across parts of Tutuila, Ofu, and Ta'u in the South Pacific. NPS describes the park as including about 9,500 land acres and 4,000 marine acres, mostly coral reefs, while the official national park acreage commonly listed for ranking purposes is 8,256.67 acres. The park recorded 43,258 recreation visits in 2025, making it one of the least visited national parks despite its rare ecosystems and island setting.
This is the only national park south of the Equator and one of the most distinctive units in the National Park System. Visitors can experience rainforest ridges, flying fox habitat, coral reef waters, village landscapes, and wide views over Pago Pago Harbor and the Manu'a Islands. Travel planning matters more here than at many mainland parks because inter-island transportation, weather, lodging, trail conditions, and local customs all shape what is practical on a visit.
The park was authorized on October 31, 1988, and its land base was established in 1993 through a lease agreement rather than federal land ownership. That arrangement reflects the Samoan communal land system and makes local partnership central to the park's identity. The park protects natural resources while also honoring a living culture, so visitors should treat villages, trails, beaches, reefs, and sacred places with care.
Hiking and Backpacking
The official NPS Hiking page is the best starting point for trail planning. Routes range from short coastal and cultural walks to more demanding rainforest ridge hikes, with options such as Mount Alava, Lower Sauma Ridge, Pola Island, and trails on Ofu and Ta'u. Conditions can be hot, humid, muddy, and steep, so water, sun protection, insect repellent, and current trail information are important.
Backpacking is not a standard activity here. NPS Laws and Policies state that overnight camping is not allowed in the park except where specifically authorized, so visitors should plan day hikes rather than overnight backcountry routes. Longer adventures are best organized around lodging, local transportation, and realistic travel time between islands.
Planning Highlights
Tutuila offers the visitor center in Pago Pago, Mount Alava, Lower Sauma Ridge, Pola Island views, and access to village and coastal scenery. Ofu is known for its beach, reef, and quiet South Pacific setting, while Ta'u offers rainforest, volcanic slopes, and a deeper sense of remoteness. The NPS Places To Go and Plan Your Visit pages are useful for deciding which island or islands fit a trip.
Camping and Lodging
There are no developed NPS campgrounds in the park, and overnight camping is generally not allowed. Most visitors stay in local lodging on Tutuila, with more limited options and logistics on Ofu and Ta'u. Confirm flights, ferries, local transportation, food, and lodging before arrival, especially if visiting the Manu'a Islands.
