Korpreiret is the name of a kilometre-long, narrow canyon. A wild formation very unusual for Hedmark.
We suggest a roundtrip from Korperud along the river until the terrain levels out and you reach a forest road towards Grasrud. There are marked paths on both sides of the river and you can easily cross the river when it flows normally, but the water level quickly rises when raining.
Turn off Rv25/3 between Hamar and Elverum at Ebru (the eastern mountain road), follow signposts to Nordhue. Drive to Korperud, turn off from the eastern mountain road at Storholtet
