The farm Hraun is located west of Ölfusárós in the municipality of Ölfus. The land of “Hraunstorfan”, of which Hraun is a part, is about 2400 ha if the farm’s territorial integrity is included. The land of the farm is mostly lava, sand and moorland, and arable land is limited. Angling has long been practiced at Hraun. The fishing is often adventurously good in the area; both sea trout and char can be caught. The best opportunity for fishing is just before the inflow and during the tide. It is often better to start at the bottom of the estuary and move upwards when the tide gets higher. The fish, which are usually found in the estuary feeding on sand-eels, follow the tide up the river and then go back down to the sea when it falls again.
