In reply to andgigs:
Far be it for me to criticise, but I would have thought a month in the same spot would be "saturation" ? There are some fantastic places to climb within a relatively short-distance : Riglos, Vadiello, CienFuens, Monrebey, Montsec..............Perhaps hiring a car for a week would be a good idea ?
Likewise, there are many interesting places to visit : Alquezar, Torreciudad ( Opus Dei- not everyones cup of tea, but the architecture is stunning). Roda de Isabena.
I know the area like the back of my hand- I fish for trout in the Alcanadre !
