In reply to AlanLittle:
The Frisch - Corradini is supposed to be fantastic too, and a very logical line. However it is somewhat harder, more sustained at V rather than IV. I was there with clients who were not super experienced rock climbers so the Castiglioni-Detassis was the better choice for us at the time... it was a full day!
I would love to go back for the Frisch-Corradini though, and am planning a return trip next September so maybe.
Hope you enjoy the area and the routes! All the best,
Tania
