UNESCO World Heritage site within Durmitor National Park. Large, powerful river with excellent fly-fishing reaches: runs, pools and glides in spectacular canyon scenery. Grayling, Danube salmon (huchen) and brown trout. Limestone karst geology supports good invertebrate life. Technical nymphing and dry-fly fishing require careful reading of light and wind. June–October season. Daily zone permits; catch-and-release with barbless requirements.
