From Scharnitz along the Hinterautal to Roßloch (preferably with a bike, very flat)
From the eastern end of the Roßloch climb on a scarcely marked path into the Bockkar (markings of red paint, cairns, poles, yellow paint)
and to the bivouac shelter at 2495 m. From there on scree to the summit.
With a bike, the hike can be done in a long day (9-10 hours). It is also very nice to sleep in the bivouac shelter (6 bunk beds, sheets, no water, normally no snow in summer although the pictures might suggest the opposite)
If you have information about this route that doesn't pertain to any of the other sections, please add it here.
