Stage 2: Start via the glacier "Oberer Aletschgletscher" and the glacier "Beichgletscher" to the south-eastern foot of the Lonzahörner. From here, climb through the heavily fissured glacial channel between the two impressive rocky outcrops and ascend steeply up to the upper glacier plateau. Continue over the less steep slopes at the south-eastern foot of the summit ridge. Locate the ski depot here and continue with ease on foot along the south-eastern ridge up to the south-eastern summit.
Stage 3: Following your summit tour, savour the long descent down your ascent route back into the Lötschental Valley.
