The National Park of American Samoa in Tutuila was established in 1988 for preserving its perfect terrestrial and marine environment.
It covers an area of 2,000 ha (4,900 acres) and is bound on the north coast between Fagasa and Afono villages.
The Rainmaker pass is located within this park with its rain forests.
The Amalau Valley between the Afono and Vatia villages in the park has many species of birds and animals.
The most significant faunal species consists of the two species of the flying fox (bats), which the local Samoans consider as the protector guardian of the forest and also its people.

The two species of flying foxes (bats) protected in the park are: Pteropus samoensis (known locally as pe'a voa) meaning "fruit bat of the forests" and Pteropus tonganus locally called pe'afaunua, which means "fruit bat of settled lands"; The roosting place of Pteropus samoensis (with prominent light colored face with brown body) is the canopy of ridge top trees, which roost alone or in small groups and are active during day time with two feeding peaks, the Pteropus tonganus (with black colored face with seal brown body) species roost in large groups (100 or more in numbers in each group) in thick forest habitat, also sometimes seen close to villages.
Both species have a wing span of 1 m (3 ft 3 in) at adulthood, and weigh about 500 grams.

The park which is divided into three zones has a network of hiking trails.
The National Park Service (NPS) maintains good information system about these trails.
One such trail goes up the Mount Alava, a high peak within the park rising to a height of 491 meters (1,611 feet).
A TV tower exists on this mountain and also the ruins of a cable car station of a 1.8 km (1.1 mi) long cable way which once ran over Pago Pago Harbor to Solo hill in Utulei. (
524m).
This cable way, which was the only single way cable in the world at that time built in 1965, was damaged when a Navy plane attempted to fly under it and was caught by one of the cables, on April 17, 1980 and was permanently put out of commission.
The cable way was used to transport the TV technicians to the transmission station.
The descent from the peak passes through lovely vistas of the lowlands of the park and the rain forests which abounds in several bird species.
Another ridge trail runs from Fagasa Pass over a length of 6.5 km (4.0 mi), goes through a very steep slopes behind the rest fale (hurricane shelter), which is also negotiated through a stairway and further leads down to the serene Vatia village on the coral bay.
