Hardangervidda National Park, at 3,422 square kilometers, is Norway's largest national park. It spans from Numedal and Uvdal in the east and Røvelseggi and Ullensvang in the west across the Hardanger mountain plateau (Hardangervidda). Designated as a national park in 1981, today it serves as a popular tourist destination for activities such as hiking, climbing, fishing, and cross-country skiing. The Norwegian Mountain Touring Association (DNT) maintains a comprehensive network of huts and paths across Hardangervidda. The Bergensbanen railway line and the main Highway 7 cross the plateau.
