It springs below Mount Vlasic at the village of Vrbanja, at an altitude of 1520 m. It flows into Vrbas River as its right tributary, near Banja Luka. Vrbanja is a mountain river with lots of tributaries rich in high quality fish.
In its upper part (the reach from K. Brdo to the town of Kotor Varos), the river is very clean so that the area is rich with rainbow trout and Danube salmon, as well as other types of white fish (sneep, barbel, pomfret).
