The mountains between Gausdal and Valdres is called Huldreheimen, or “the home of Huldra”, Huldra being a beautiful and seductive female forest creature from Norwegian folklore. The area is a remote wilderness dominated by marshes flanked by pine and birch woods, and with a rich bird life. The only traces of human activity is a limited degree of traditional dairy farming. From the parking at Ormsjøsætra farm, you can hike south to Oppsjømyra marshland, where Broad-billed Sandpiper breeds. The path north to the great viewpoint Ormsjøkampen leads through nice Siberian Jay habitat.
