Orkdalen

Orkdalen () is a valley and a traditional Norwegian district in Trøndelag county, Norway. In the early Viking Age, before King Harald Fairhair, the Orkla Valley was also a petty kingdom.

The valley begins in the high Dovrefjell mountains and creates a deep, narrow valley. As the river progresses, the valley widens and flattens out. From Rennebu northwards, the valley is fairly heavily populated with good farmland. At the mouth of the river (the north end of the valley) is the town of Orkanger, the largest population centre in the valley.
