The National Park of American Samoa spans the islands of Tutuila, Tau and Ofu and was established primarily to protect the area’s tropical rain forest. On Tutuila, the park runs from the ridge above Pago Pago Harbor to the northern coast. The forest’s Amalau Valley is home to a variety of flora and fauna, including two species of flying fox, or fruit bat. Hikes in the park include climbing 490-meter-high (1,600-foot-high) Mount Alava. The trail can be accessed at Fagasa Pass and is 9.5 kilometers (six miles) roundtrip.
