The Sava River represents the natural northwestern boundary of the Balkan Peninsula and it flows through four countries - Slovenia, Croatia, Bosnia and Herzegovina and Serbia. From its source in the Julian Alps in Slovenia, the Sava Rivers flows southeastward for about 940 km, through Croatia, along part of Bosnia and Herzegovina's northern border, and into Serbia, where it merges with the Danube River in Belgrade.
It is the main tributary of the Danube River.
The main tributaries of this mellow turquoise river are the Una, Vrbas, Kupa, Ukrina, Bosna, Tolisa, Brka, Lukavac and Drina rivers. The River Sava has two sources, both in the Alps of Slovenia - the spring of Sava Dolinka sources and other spring Savica, which flows into the Lake Bohinj and emerges on the other end as a new river - Sava Bohinjka.
The River is navigable for almost 600 kilometers and smaller crafts can navigate further all the way until Zagreb, depending of the season.
