This is the classic alpine route on the German side of Zugspitze and is widely documented in guidebooks. It combines glacier travel, steep rock, and long sections of fixed protection. The route is significantly more serious than a normal hiking ascent and requires alpine experience, sure-footedness, and appropriate equipment. Objective hazards include crevasses, rockfall, and rapidly changing weather. The upper section is exposed and can be crowded in good conditions. It is commonly graded in the difficult via ferrata / alpine climbing range rather than as a simple hike.
