In reply to BoaseF:
Not sure what you mean by 'easy' or 'long' as they can mean very different things to different people ( eg novices to experienced ) or what types of climbing you may be looking for. However, here are some suggestions with the caveat that I have no idea of your experience / grades etc:
Crochues Traverse in Aiguilles Rouges
Linking some rock routes together in Aiguilles Rouges in the Brevent area
Aiguille Tours adding Tete Blanche and Petite Fourche as energy levels dictate
Aiguille Moines, Aiguille Peigne, Domes de Miage, Mont Tondu, Mont Blanc via Trois Monts
Spaghetti Route in Switzerland
Breithorn half traverse ( Castor, Pollux )
Lots of options around Arolla and Saas Fee
Linking shorter easier routes around Torino Hut
Gran Paradiso
