Review
Text is provided in both Spanish and English, however the maps are in Spanish only so if you don't have a reasonable level of Spanish you will not understand what the landmarks are although google is really useful for this :-)
Also we found that quite a bit of the access information for some crags is out of date with some of the approaches simply no longer existing (in particular Sol y Sombra)
The pictures are reasonably clear although there is some discrepancy about the lines of some climbs.
