Abkhazia is diverse geographically with lowlands stretching to the extremely mountainous north. The Greater Caucasus Mountain Range runs along the region's northern border, with its spurs - the Gagra, Bzyb and Kodori ranges - dividing the area into a number of deep, well-watered valleys. The highest peaks of Abkhazia are in the northeast and east and several exceed above sea level. Abkhazia's landscape ranges from coastal forests and citrus plantations to permanent snows and glaciers in the north of the region. Although Abkhazia's complex topographic setting has spared most of the territory from significant human development, its cultivated fertile lands produce tea, tobacco, wine and fruits, a mainstay of the local agricultural sector.
