Fantastic climb! Carlo, our superb local guide, helped me and my son Christoph in finding the best way up the buttress, and in particular how to surmount the crux IV/5.7 slab. The weather was perfect and the views along the way unforgettable.
The descent back to Diavolezza was by the standard PD route which brought to me memories from 1975, the prior time that I had been on this spectacular mountain. The Ostpfeiler route is the best way to access the summit ridge!
