In reply to dmanmn:
Its a great place to visit, beautiful. Not sure how much to go at in the lower grades, probably slightly restricted but at 6b there are certainly good routes, although going through the classic bulges which normally form the cruxes can feel tough at the grade especially if in the sun. I'm sure the odd piece of aid pulling on a quick draw etc would drop these sections though. I also pretty much just did multipitch so not sure on the single pitch options although I know there are some.
The approaches are generally short, walking steeply out of the town to the base of the towers, however if you do any multipitch that top out it is a longer walk down with steeper sections. The normal route on El Puro (6b) is an abseil descent as is chooper (only goes half way up at 6b then continues as chooperior) so there are probably other options that would be the same and minimize the need for walking.
You can easily have a look at guidebooks in the refuge as well as get decent food and a beer/vino.
Well worth a visit and not like there is a shortage of other places in Spain to visit if after a few days you want a change.
