VrbasVrbas – river and tributary of Sava in the western part of Bosnia and Herzegovina. It is formed on the Zec Mountain (branch of Vranica Mountain). The Vrbas River drains the composite valley, passing through Skopaljska valley, Vinačka klisura, Jajce valley, the canyon valley Tijesno, Banja Luka valley, and in the lower flow through Lijevče field. Going south, Vrbas created a fantastic canyon in which there are series of natural rarities. River rapids, waterfalls, cascades, beaches, surrounding rocks, and the richness of the plant and animal world make this area special. The specificity of this river are also the Banja Luka boats – dajaks, named after a pole that serves to push the boat.
