Located in eastern Tanzania, much of the Selous is low lying, with altitudes ranging from 110 to 1200 meters. Running through its center flows the vast Rufigi River. Together with its tributaries, the Great Ruaha, Kilombero and Luaga, the Rufigi makes up East Africa's longest river basin.
An unusual combination of steep wooded hills, open Miombo woodland and grassy plains and marshes interlaces with lakes and dry sand rivers, this scenic area boasts an impressive variety of game, birds and wildflowers.
