Hörðudalur is the southernmost valley in Dalasýsla. River Hörðudalsá flows through it, but the valley splits into Vífilsdalur and Laugardalur. The valley runs south from Hvammsfjörður and the whole environment is especially beautiful. Hörðudalsá was an excellent Arctic char river and in a good summer over 1000 fish were caught there. However, in recent years, the char fishing has declined as in many other parts of the country. In recent years, eggs have been buried in Laugá and salmon have been transported to the non-fishable part of Hörðudalsá in consultation with fisheries scientists. These are factors in making the river sustainable. The salmon fishing has been considerable, ranging from around 20 up to about 120. Two days are sold at a time, from noon to noon.
