The Korana is a river in central Croatia and west Bosnia and Herzegovina. The river has a total length of 138.6 km (86.1 mi) and a watershed area of 2,301.5 km2 (888.6 sq mi).
Korana rises in the eastern parts of Lika, creates the world-famous Plitvice Lakes, a UNESCO World Heritage Site. Downstream from Plitvice Lakes, the Korana river forms a 25 kilometers long border between Croatia and Bosnia and Herzegovina near Cazin. From there it flows northwards through Croatia, where it finally reaches the river Kupa at Karlovac.
