V¿ringfossen is one of the most visited waterfalls in Norway. The falls are 183 m (about 600 ft.) high. The falls are located in Eidfjord not far from Highway 7, which connects Oslo with Bergen. Bjoreia, the small river that flows into V¿ringfossen, has a hydroelectric dam in the Sysendalen valley above the falls, reducing the flow of water. In summer, the flow is increased to 12 m3/s, above its natural rate, not least to benefit the tourist trade.
