Fossálar is a water-rich river that originates south of Miklafell on Austur-Síðuafréttir, at about 600 meters above sea level, and flows to Skaftá east of Síðunni. Sea trout are the main catch in Fossálar, but char are sometimes caught in the early summer. Autumn fishing for sea trout is, however, the hallmark of Fossálar. There are many fine fishing spots with some deep pools in beautiful surroundings. It is worth paying some attention to the Syðri-Ál area, as there is often good fishing there, although it leaves little to be desired. The fishing is for char in the first half of the summer and sea trout in high summer.
