Drina

The Drina is a 346 km long Balkans river, which forms a large portion of the border between Bosnia and Herzegovina and Serbia. It is the longest tributary of the Sava River and the longest karst river in the Dinaric Alps which belongs to the Danube river watershed. Its name is derived from the Roman name of the river which in turn is derived from Greek.

The Drina originates from the confluence of the rivers Tara and Piva, in the glen between the slopes of the Maglić, Hum and Pivska Planina mountains, in the area of Šćepan Polje and Hum villages.
