Rangá has its source in numerous small streams in the eastern part of Kinnarfjöll. It flows parallel to the highway and joins the River Skjálfandafljót. Not many anglers have experience of this river, but Ingvar Karl Þorsteinsson, an angler from Akureyri, is familiar with it. He says the upper part of the river is a paradise and that often there are good numbers of fish after 15 July. Rangá fish are easily scared and Ingvar says that he has never seen fish in the river, only caught them by casting a long distance. The river meanders down the valley and in most of the bends, it forms beautiful little ridges where the fish lie under the banks. It is possible to get a good catch by being careful; fish all the way up to 3 pounds.
