I am very envious. I have seen photos of a tourist wolfwatching trip to Spain. The habitat looks like open scrubland to me. The watchers successfully saw wolves on about two days out of seven.
You're right , the habitat is really very disappointing, it's mostly replanting pines, no oak forests or those types of vegetation that you hope to see in the NW of Spain, mostly are heather and pine.But it's a very good place for to see wolves. deers and roe deers too.
