Topographically, Angola consists mainly of broad tablelands above 1,000 m (3,300 ft) in altitude; a high plateau (planalto) in the center and south ranges up to 2,400 m (7,900 ft). The highest point in Angola is Mt. Moco, at 2,620 m (8,596 ft), in the Huambo region; other major peaks are Mt. Mejo (2,583 m/8,474 ft), in the Benguela region, and Mt. Vavéle (2,479 m/8,133 ft), in Cuanza Sul.
Rivers are numerous, but few are navigable. There are three types of rivers in Angola: constantly fed rivers (such as the Zaire River), seasonally fed rivers, and temporary rivers and streams. Only the Cuanza, in central Angola, and the Zaire, in the north, are navigable by boats of significant size.
