In reply to LemonFresh:
I assume you are looking at going in the summer / autumn?
If so, check out routes on the Aiguilles Rouges side of the valley - something like the Crochues Traverse or Clocher-Clochetons Traverse. Both easily accessibly from the valley floor and doable in a single day.
Higher up, you could possibly do a traverse / half traverse of the Midi Plan from the Aiguille du Midi. Check out the traverse of Pointes Lachenal just across the Col du Midi.
From the Italian side you could do something on the Aiguille Marbrees, and if you're really fast, perhaps something on the Aiguille d'Entreves.
Les Gaillands is great if you want to spend the day cragging in shorts and T-shirt, however, be prepared to fight for breathing space as it can become incredible busy.
As your guide / local friend, they will know best no doubt...
