This is the standard and best-known mountaineering route on the Jungfrau. It is primarily a snow-and-ice ascent with some exposed ridge climbing near the top. The route is usually approached from the Jungfraujoch, making it one of the shortest classic 4000-m peaks in the Alps. Objective hazards include crevasses, avalanche danger, and rapidly changing weather. The upper section can be heavily corniced and exposed to wind. Conditions vary significantly with season and snow cover, so route-finding is important.
