The Hohlaubgrat is a well-known alpine ridge route on the Allalinhorn and is more demanding than the normal glacier route. It combines snow, ice, and some rocky sections, so it is a more serious mountaineering objective. The route is valued for its more alpine character and typically requires better route-finding and more secure movement than the standard ascent. Objective hazards include crevasses on the approach and changing snow conditions on the ridge. It is generally considered a classic moderate alpine climb rather than a pure snow walk. In poor conditions it can become significantly more difficult.
