Bächlitalhütte, 2328 m

Gross Grünhorn is the only 4000 meter in the Konkordiahütte area. The ascent leads from Konkordiaplatz along the edge of the Ewigschneefeld glacier and then along the northwestern slopes of the Grünhorn ridge. Beware of glacier cracks around the saddle between Grünegghorn and Gross Grünhorn. Not far from the saddle is a ski depot, from which you can go up with crampons and ice ax. The descent along the ascent route is safer than the descent variant through Grüneggfirn (glacier cracks).

The stage begins at the Cabane Tracuit with an ascent of the 4,000-meter peak Bishorn, which is considered relatively easy. After skiing back down to the Tracuit hut, the route continues with a descent over the Turtmanngletscher glacier. A subsequent climb over the Brunegggletscher glacier leads into a rocky corridor, which marks the beginning of the descent to the Turtmannhütte.
