In reply to Caralynr:
Good summary. I had a brilliant March trip there in 1990 & there wasn't much info around then. Did Grade IIish routes on all the 4000m peaks plus a few others in perfect snow conditions. If you're going back I recommend the N Face of Aksoual above Tachdirt which is huge, with routes of all standards possible. I did a fairly prominent rib near the left hand end at grade II - the 5000 foot glissade down one of the gullies definitely sticks in my mind (& bum!)too. The people in the villages were incredibly friendly & helpful.
