Jostedøla (or Jostedalselva) is a river which runs through the Jostedalen valley in Luster Municipality in Vestland county, Norway. The Jostedøla river begins near the Fåbergstølen mountain farm where the runoff from the great Jostedalsbreen glacier and the lakes Austdalsvatnet and Styggevatnet comes together in the Jostedalen valley. It then flows south for about 50 kilometres (31 mi), through the Jostedalen valley, and finally empties into the (a small arm off of the Sognefjorden) at the village of Gaupne. The river is the main collector of water for an 804-square-kilometre (310 sq mi) watershed area. The river is great for fishing trout and some salmon.
