Nr 1 Grandane elveosen This is where the salmon meets its home river again, on its final mission; spawning! The salmon swim up the river during all the spawning season, but when the tide is coming in this often triggers the salmons going up stream! The river is canalised and the riverbank is plastered, the depth is equal in all the zone and the current runs even. Fretheim Hotel manages the south bank in this zone.
