📍 Destination Overview
Banja Luka is the capital of the Republika Srpska entity and Bosnia's second city, set along the Vrbas River. Cafes and tree-lined boulevards line the water, while the medieval Kastel fortress still stands quietly on the riverbank, its origins reaching back to Roman times. Banja Luka is also one of the most accessible whitewater-rafting spots in the Balkans, with the Vrbas slicing a deep canyon ideal for rapids and scenery - alongside Ottoman mosques, thermal springs and a lively nightlife scene.
