Field briefing

National Park of American Samoa starts with access, not mileage.

Before you go

National Park of American Samoa is the only U.S.

national park south of the equator, spread across the islands of Tutuila, Ofu, Olosega, and Ta'u in the South Pacific. It protects tropical rainforest, fruit-bat skies, and Indo-Pacific coral reefs, and it is one of the least-visited parks in the system, so solitude is the norm. Go in the drier June to September window for the best snorkeling and fewer washouts. Plan around tropical heat and rain year-round: pack a real rain shell, reef-safe sunscreen, snorkel gear, and trail shoes that handle slick, muddy ridge climbs. This is a cultural park as much as a wild one, so come ready to respect fa'asamoa and village customs.

Crowds by month, from NPS visit counts

Busiest: April. An average April brings about 4,800 recreation visits to National Park of American Samoa, roughly 160 a day. Peak crowds run April and July and September.

Quietest: December. About 580 visits, 12% of the busiest month. Crowds stay low June and August and December.

Limited data. NPS counts fewer than 50,000 recreation visits a year here, so monthly numbers are small and can swing on a few groups or a change in how visits are estimated. Read the shape of the year, not the exact figures.

  • Low
  • Moderate
  • High
  • Peak

Bar height is each month's average visits compared with the busiest month. Low is under 25% of that peak, Moderate 25 to 49%, High 50 to 74%, Peak 75% and up.

How long to spend

Anchor the day around Mount Alava Trail

Treat transport weather as part of the itinerary, with a real buffer day instead of a tight turnaround. For one day in National Park of American Samoa, make Mount Alava Trail the non-negotiable, add Pola Island Trail only if the first stop runs clean, and keep Ofu Beach as the flexible finish.

  1. 1Start with Mount Alava Trail: Tutuila's signature ridge climb to a 1,610-foot summit with sweeping views over Pago Pago Harbor.
  2. 2Add Pola Island Trail: A short, flat walk in Vatia to a rocky shoreline facing the park's top seabird nesting cliffs.
  3. 3Use Ofu Beach as the optional finish, not as a reason to rush the whole day.

Where to stay

Stay strategy

Make the access plan before the lodging plan.

Stay strategy

Base on Tutuila first, add Ofu only when the transport window works.

This park is logistically different from a mainland trip: there are no park campgrounds or lodges, and the islands do not behave like a simple road loop. Use Pago Pago for Tutuila hikes, consider a village homestay only if current options can be confirmed, and treat Ofu as a separate commitment with buffer days.

Planning detail

The NPS eating and sleeping page covers the park's lodging options and is not a current host list. Contact the park or local visitor resources to verify whether homestays are currently available, then confirm meals, Sunday customs, transportation, and village expectations before committing.

Ofu Beach with white sand, reef water, and green volcanic slopes

Remote reef base

Ofu lodging

Best for
Travelers prioritizing Ofu Beach, reef snorkeling, and the Manu'a Islands
Tradeoff
Limited flights and weather delays can reshape the trip.
Planning detail

Small lodges near Ofu Beach put you close to the reef, but the extra island transfer needs flexible dates and a tolerance for schedule changes.

Buffer days

Do not schedule an international departure immediately after an Ofu transfer day.

Reef respect

Pack reef-safe sun protection and avoid standing on coral when snorkeling.

Camping reservations

Camping reservations

There are no campgrounds here; the village homestay program is the real overnight system.

National Park of American Samoa has no campgrounds, no developed campsites, and no reservation platform, so do not plan a tent-based trip. The park's homestay program, staying with Samoan host families in the villages whose land makes up much of the park, is the overnight experience worth planning around.

Reviewed June 11, 2026

Booking window

There is nothing to book online: homestays are arranged through the park visitor center in Pago Pago, and flights to American Samoa run only a few times a week, so start the conversation well before you travel.

  • Much of the park sits on land leased from Samoan villages, which is exactly why there is no campground system; respect village protocols wherever you go.
  • Homestays are coordinated by the park, which keeps the list of host families; contact the visitor center by phone or email to arrange one, and expect to settle details directly with your hosts.
  • If a homestay is not your style, base in Pago Pago hotels on Tutuila, or at Vaoto Lodge or Asaga Inn on Ofu for the Manu'a Islands.
  • Observe fa'asamoa: ask before walking through villages, dress modestly, and plan around Sunday, when most village activity pauses.

Frequently asked questions

Is National Park of American Samoa free to visit?

Yes. There is no entrance fee and no reservation or timed-entry system. Note that much of the park sits on land leased from Samoan villages, so visitors are expected to respect local customs and any village access rules.

How do you get to National Park of American Samoa?

Fly into Pago Pago International Airport (PPG) on the island of Tutuila, typically on a once-or-twice-weekly Hawaiian Airlines flight from Honolulu. The Tutuila trailheads are a short drive from the airport. Reaching the Manu'a Islands sections (Ofu, Olosega, Ta'u) takes an additional small-plane flight or boat.

When is the best time to visit National Park of American Samoa?

The drier season from June to September is best, with lighter rain and the calmest, clearest water for snorkeling. It is tropical and warm all year, with highs in the 80s F. The wetter, hotter months from roughly November to April bring heavy rain and the cyclone-season risk window.

What is there to do in the park?

Day-hiking, snorkeling the coral reefs, and wildlife viewing are the highlights. Hike the Mount Alava Trail above Pago Pago Harbor, walk the short Pola Island Trail to the seabird cliffs, and snorkel the reefs off Tutuila or the standout Ofu Beach. The park protects fruit bats, hundreds of fish and coral species, and native rainforest birds.
