The river Andakilsa is one of many in the western part of the country. It discharges lake Skorradalsvatn and has been harnessed for electrical production. One of the oldest swimming pools of the district is situated near the power station.

The trout and char fishing area is the lower part of the river (7 km), between the power station and the bridge on road no. 53. The catch consists of lake char, brown trout and  an occasional salmon. The distance from the capital is about 68 km by the Whale Bay tunnel and 15 km from the town Borgarnes.
