Lierne National Park lies in Lierne Municipality in Trøndelag county, Norway. The 333 km2 park was established on 17 December 2004 by a royal resolution. The park covers 333 km2 of land along the border with Sweden. The park lies east of the populated areas in Lierne Municipality, about 12 km southeast of the village of Sandvika and about 6 km northeast of the village of Mebygda. The park is dominated by a large mountainous region rich in lynx, wolverines, bears, and wildfowl. The rare Arctic fox also lives in the area. Much of the land was formed during the last ice age. There are many peaks over 1000 m above sea level, the highest of which is Hestkjøltopp at 1390 m. There are many wetland areas with large swamps and open woodlands.
