American Samoa National Park
The National Park of American Samoa is the only U.S. national park south of the equator, a scatter of paleotropical rainforest, coral reef and volcanic coastline across three remote South Pacific islands. Unusually, the land isn’t owned by the federal government; it is leased from the Samoan villages who have lived here for 3,000 years, so a visit blends pristine wilderness with a living culture, nearly 2,600 miles (4,200 km) southwest of Hawaii.

The landscape
This is a park of ocean depths and cloud forests in one small footprint. Coral reefs and littoral vegetation give way to tropical rainforest climbing steep volcanic ridges, with sea cliffs that stairstep more than 3,000 feet (900 m) to the summit of Lata Mountain on Taʻū, among the tallest sea cliffs in the world. Nearly as much of the park lies underwater as above it, making it a rare pairing of terrestrial and marine protected ecosystems, right down to white-sand beaches on Ofu.
Best time to go
American Samoa has two tropical seasons: a wet season of heavy rain and humidity, and a drier, slightly cooler season. The best window is June to August, within the broader dry season of May to October, when temperatures run 75–84°F (24–29°C) and trails stay firmer. The park is open year-round, but some services run reduced hours in the wet season, so check ahead.
Getting there and around
Access is by air and sea, with the main gateway at Pago Pago International Airport on Tutuila, where the park headquarters sits. Flights connect from Honolulu about twice a week, a journey of roughly 5.5 hours, and smaller flights reach the Taʻū and Ofu units. Plan travel well ahead and stay flexible, as weather can affect flight and boat schedules; on Tutuila you get around by car.
Things to do
Hiking through rainforest ranges from gentle strolls to steep climbs to ridgeline viewpoints and secluded beaches. Snorkeling the vibrant reefs, the south coast of Tutuila is a highlight, is a must, and wildlife includes fruit bats, seabirds and abundant marine life. Cultural experiences are woven throughout: learning the Faʻasamoa way of life, watching a traditional umu earth-oven cooking demonstration, and taking in the great sea cliffs at Siʻu Point on Taʻū.
Staying safe
Check marine and weather forecasts before any outing, as tropical conditions shift fast, and be cautious near the coast where currents can be strong and unpredictable. Stay on designated trails to avoid injury and protect the fragile ecosystem, carry plenty of water and sun protection against the heat and humidity, and don’t fly drones. When visiting villages and cultural sites, dress modestly and ask permission before photographing people. The remote location means limited emergency services, so be self-sufficient and share your plans.
Know before you go
The park is free, but flights, lodging and food are limited and can be costly given the remoteness, so budget accordingly. American Samoa uses the U.S. dollar, and both English and Samoan are spoken. Above all, remember this is living land belonging to the Samoan people, learn about Faʻasamoa and respect local customs. This page is a general overview, not a live conditions report; confirm current conditions, flights and village access with the National Park Service before your trip.
