From Trient hut (3170 m) cross the Trient Plateau in WSW direction, conturn the crevassed zone on the right to reach the Purtscheller Collar (3383 m).
From the Collar, a snow slope leads to the foot of the NE face. Climb some rock tiers, staying on the right. A not well marked couloir leads oblique to the left and reaches the N ridge.
This ridge leads easy to the summit.
This is the normal route to Aiguille Purtscheller and the route of the first climber, Ludwig Purtscheller.
Climb down 10 meters through the NE couloir. Here is the equipped abseiling route (2 abseilings of 30 meters). If the snow slope underneath is icy, a third abseiling length is necessary.
Ice-axe, crampons, rope for abseilings of 30 meters.
