Mountains cover the largest parts of the country. Four mountain systems meet in Serbia: the Dinaric Alps in the west cover the greatest territory, stretching from northwest to southeast. The Carpathian and Balkan Mountains stretch in a north-south direction in eastern Serbia, east of the Morava valley. Ancient mountains along the South Morava, the highest one being Besna Kobila, belong to the Rila-Rhodope mountain system.
