Lygne is a lake in the municipality of Hægebostad in Agder county, Norway.[1] The 7.56-square-kilometre (2.92 sq mi) lake is part of the river Lygna. The lake begins near the village of Eiken in the north and stretches about 10.4 kilometres (6.5 mi) to the south to the village of Tingvatn.[2] Part of the western shore has fairly steep cliffs overlooking the lake, but the rest of the shoreline is relatively flat with houses and roads.
