From the village of Tvebish, there is a popular ridge that even provides a nice tree run.
10 minutes from Tvebish you can get on skis and head for the forest, following a path that is noticable under the snow (it’s a marked GR route). Than follow the GR to the pass and from here we continue to the right following the ridge untill you reach the summit.
From the summit it’s also possible to traverse more to the left, but than you need a car to get back to the start point. There is a road connecting the whole east face of the mountain.
