Ascent
From the parking lot, first head southwest, then west, leaving the hut on your right. It is best to bypass the lake to the north. The terrain here is somewhat confusing and you won't always find the ideal ascent track. As this is obviously the case for many ski tourers, there are often suboptimal tracks to be found. After the lake, depending on the snow conditions, either the path through the mountain pines (when there is a lot of snow) or the variation through the forest (when there is little snow) is the better option.
Soon, however, you have left these small initial problems behind you and ascent in hairpin bends over a steeper slope to the southwest before a short, often somewhat unpleasant crossing to the northwest follows (clever ski tourers descent the 20 m to the valley here and ascent again after the crossing). After a short flat section, where you head west below the summit slope of the Großer Bösenstein, you then turn off again onto a steeper slope to the northwest, which takes you to the summit ridge. Depending on the snow conditions, you can simply continue here with skins, or you may have to strap your skis onto your backpack. Late in spring, it may not even be worth taking your skis to the summit. In any case, the ascent via the summit ridge is quick and not too difficult.
