> You might want to consider the crags in Pete O'Donovan's guidebook to LLeida as they include a lot of stuff that is either shaded for some of the time or is further into the Pyrenees and therefore higher.
Asturias also good. You'll have to hunt a bit for shade but I'm assured it's cooler than the rest of Spain. Climbing excellent and it's a beautiful place. It's quiet - no one goes there!
