From the hut follow the path descending SW beneath the rocky buttress of the Hinter Allalin ridge to get onto the Hohlaub Glacier. Go SSW across the Hohlaub Glacier passing under point 3150m to gain the Allalin Glacier. Follow the R side of the glacier SW under the large cliffs to your R, negotiating your way round the crevasses, before the angle eases off around 3250m. The route now heads L slightly, SW, avoiding a crevassed area beneath the Rimpfischhorn and climbs normally without undue difficulty to the Adlerpass, 3789m.
