About this water

Brown trout and grayling in clear limestone water. Larger than many Bosnian tributaries, offering varied fly water with pools, runs, and riffles. Part of the western Bosnian karst river network that produces some of the best grayling water in the Balkans. Lower down, where the valley opens and the current slows through deeper bends, huchen hold in the big pools.
