Guastatoppen is the highest mountain in Telmark county, Norway. With its 1883 meters of height, it offers an incredible panorama of about 1/6 of the Norwegian mainland. The mountain is famous for downhill skiing in the winter and the competitions that have been held on its slopes, such as the "Norseman triathlon". The Gaustatoppen holds the wreckage of a plane crash, left here due to the difficulty in removing it.
