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 metres (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)[15] long cable way which once ran over Pago Pago Harbor to Solo hill in Utulei. (524m[1]). 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.[15]
