Hiking in American Samoa: The Best Trails for Every Skill Level

By Erika Müller · Data: National Park Service · ← Complete guide American Samoa

Let's be honest: the National Park of American Samoa isn't Yosemite. You won't find packed parking lots, trail markers every 150 feet, or crowds on the trails. What you will find is some of the best-preserved old-growth rainforest in the Pacific, a handful of trails that live up to their reputation for difficulty, and enough solitude to remind you why you came hiking in the first place.

The hike you shouldn't miss is the Mount ʻAlava Trail. This ridge trail on Tutuila climbs to 1,611 feet, with sweeping views over Pago Pago Bay and the coral reefs. Two strong alternatives depend on your time and experience: the World War II Heritage Trail (1.2 miles, easy, with history and vegetation along the way) for an effortless introduction, and the Lata Mountain Trail on Taʻu for hikers looking for complete isolation and a serious climb.

How to Prepare for a Hike in American Samoa

Permits and entry. You don't need a permit for day hikes in the park. Entry is free, and no reservation is required.

Dogs. Pets aren't allowed on trails in the national park.

Water. The park's springs and streams aren't safe to drink from. Bring at least 2 liters per person for a half day, and more for a full day or in hot weather.

Wildlife to know. The park is home to pe'a, Samoan flying foxes, a large fruit bat species listed as endangered. If you see one on the ground or within reach, keep your distance and don't touch it. Tropical centipedes live under rocks and logs. Their bites hurt but aren't dangerous. The park has no large land predators.

Heat and humidity. Temperatures range from 75°F to 90°F year-round, and humidity is often above 80 percent. Set out early, before 9 a.m., for longer hikes. Avoid hiking in the middle of the day. The combination of heat and humidity wears you down quickly, even if you're an experienced hiker.

Rain. Tropical showers can appear at any time, including during the so-called dry season. A lightweight poncho is essential in your pack. After rain, clay trails and exposed roots become extremely slippery, so lug-soled shoes are a must.

Trail markers and navigation. Signage is less extensive than on the mainland. Download the park maps for offline use before you leave. The visitor center in Pago Pago village, open weekdays from 8 a.m. to 3 p.m., can tell you about trail conditions before you set out.

Basic safety. Tell someone your route and expected return time. Cell service is limited in some areas, especially on Taʻu and Ofu.

The Best Hikes, Area by Area

The National Park of American Samoa stretches across three separate islands: Tutuila, the main island where Pago Pago is located, Taʻu, and Ofu-Olosega. Each area has its own trails and terrain.

Tutuila: Mount ʻAlava Ridge and the Vatia Hills

Mount ʻAlava Trail. About 4.3 miles one way, roughly 1,600 feet of elevation gain, 3 to 5 hours of hiking, difficult, out-and-back or a traverse with a different pickup point.

This is the park's signature trail. You climb from Fagasa Pass, or from the cable-car station at the Pago Pago end, through old-growth rainforest before reaching the summit of Mount ʻAlava at 1,611 feet. From the top, you'll get 360-degree views of Pago Pago Bay, the reefs, and the coastal cliffs. On the way up, you have a good chance of spotting pe'a clinging to the canopy. The vegetation changes with elevation: coconut palms at the bottom gradually give way to tree ferns and orchids.

Start: Fagasa Pass or the cable-car station parking lot on Tramway Road in Pago Pago. If you arrange a shuttle, the north-side descent gives you access to the Vatia area.

Seasonal tip: start before 8 a.m. for the clearest views, before afternoon clouds cover the summits.

Tuafanua Trail. About 1.9 miles round-trip, moderate elevation gain, 1.5 hours, moderate, out-and-back.

This trail starts in Vatia village and reaches a coastal ridgeline above the bay. The views of Vatia Bay and the coral islets make the hike worthwhile. It's also one of the best places in the park to see flying fox colonies in their natural habitat. It's less strenuous than the Mount ʻAlava Trail, but wilder and much less crowded.

Start: Vatia village, about a 30-minute drive from Pago Pago.

World War II Heritage Trail. About 1.2 miles round-trip, almost no elevation gain, 45 minutes, easy, out-and-back.

This historic trail follows American military positions from World War II. Bunkers, gun emplacements, and observation posts emerge from the vegetation. The forest has reclaimed the ruins, giving the trail an eerie quality that's surprisingly striking. It's accessible to everyone, including children.

Start: Fagasa village, at the trailhead sign.

Taʻu: Into the Pacific's Wild High Country

Lata Mountain Trail. About 6.2 to 8.7 miles round-trip depending on the starting point, roughly 2,950 feet of elevation gain, 6 to 8 hours, very difficult, out-and-back.

Taʻu is the park's most remote island. The trail to Mount Lata, the territory's highest point at about 3,169 feet, crosses dense, nearly untouched rainforest, some of the best preserved anywhere in the South Pacific. You may see no one at all. The sense of isolation is complete.

This trail requires excellent fitness, careful navigation because trail markers are minimal, and ideally an escort from a local resident or guide. Keep in mind that you can reach Taʻu only by plane from Pago Pago. Flights are infrequent, so book ahead. Contact the visitor center before attempting the hike to check trail conditions.

Start: Fitiuta village, Taʻu.

Ofu: Short but Spectacular

Ofu coastal trail. About 1.2 to 2.5 miles depending on the route, almost no elevation gain, 1 to 2 hours, easy, point-to-point.

On Ofu, the trails are short, but they lead to one of the South Pacific's most isolated beaches and an exceptionally healthy coral reef. Coastal forest quickly gives way to views of the lagoon. Most visitors pair the hike with a snorkeling session. That's the best way to do it.

You can reach Ofu by plane from Pago Pago. Plan to spend at least one night there to make the trip worthwhile.

Easy Hikes for Families

The park isn't the most accessible part of the NPS system. Heat, humidity, and occasionally slippery trails demand real effort, even on short hikes. Still, two options work well with kids.

The World War II Heritage Trail on Tutuila is 1.2 miles long, almost flat, and easy to follow both visually and historically. Kids as young as 6 should have no trouble. The historical element helps hold their attention.

The Ofu coastal trail is flat and offers a short walk toward the beach. The reward at the end, swimming and snorkeling, gives young hikers a very concrete reason to keep going.

The basic rule for every family outing is to start before 9 a.m. and be back before noon. In the afternoon, the combined heat and humidity can wear kids out very quickly. More practical advice for visiting American Samoa with kids rounds out these guidelines.

Challenging Hikes and Long Days

The Mount ʻAlava Trail remains the benchmark for a great day on Tutuila: significant elevation gain, old-growth rainforest, and panoramic views. If you want to extend the outing, connect it with the Tuafanua Trail via Vatia and turn the day into a full traverse, as long as you arrange a ride back from the village.

The Lata Mountain Trail on Taʻu is in a category of its own. It's a full day in demanding terrain, through a forest barely touched by human activity. If you're looking for a true sense of Pacific wilderness, it's the park's strongest experience and one of the rarest in the entire NPS system. We recommend not attempting it alone and letting the visitor center know your plans.

Access, Trailheads, and Parking

On Tutuila. Pago Pago village is the logical starting point for the vast majority of hikers. Fagasa Pass, the Mount ʻAlava Trail's trailhead, is a 15- to 20-minute drive away. Vatia village, the starting point for the Tuafanua Trail, is about 30 minutes away. Informal parking is available near the main trailheads.

The park doesn't have an official shuttle. Aiga buses, Samoan shared taxis, serve Tutuila's villages, but their frequency is unpredictable and schedules vary. The most reliable option is a rental car or a ride arranged through your lodging.

On Taʻu and Ofu. You must fly there from Pago Pago. Flights are infrequent and seats are limited, so book ahead. On both islands, you can reach the trails on foot from the villages, so you don't need a vehicle.

For transportation and getting around the island, the American Samoa access guide and the national park overview provide more information.

When Should You Hike in American Samoa?

The most comfortable window is June through September. The so-called dry season is slightly less humid, and the risk of cyclones is close to zero. This is when the trails are generally in the best shape, especially the muddy trails on Taʻu.

From October through May, tropical rains are more frequent and the risk of storms is real. Some trail sections may close temporarily after periods of heavy rain.

That said, “dry season” is a relative term. The wettest areas receive 118 inches of rain a year, so expect a few showers whatever the season. Keep a poncho in your pack.
