About this water

Norway's most famous grayling river — long glides, rich insect life, and big grayling (40–50 cm regularly). Also holds excellent brown trout. Technical dry-fly and nymph fishing over visibly feeding fish. CDC emergers, Klinkhåmers, and small dries are the standard approach. Prime window July–September. Local fiskekort required. A counterweight to Norway's salmon-dominated image — proof that Norway offers world-class trout and grayling fishing too.
