The Hardangervidda is a mountain plateau in the Hardanger region of western Norway. It is the largest such plateau in Europe, with a cold year-round alpine climate and is the site of one of Norway's largest glaciers. Much of the plateau is protected as part of Hardangervidda National Park; it is a popular tourist and leisure destination for many outdoor activities. The region is divided administratively between the counties of Buskerud, Hordaland, and Telemark.
The plateau is the largest peneplain (eroded plain) in Europe, covering an area of about 6,500 km2 (2,500 sq mi) at an average elevation of 1,100 m (3,500 ft). The highest point on the plateau is the Sandfloeggi, which reaches a height of 1,721 m (5,646 ft).
