Thanks Stephen for your questions - I hope you don't mind me sharing them alone with the answers.
1 Cows. You mention that walkers on the GR1 will see herds of cows. My wife and daughter have been known to refuse to walk through a field of cows in this country. (My wife and I got charged by a herd once in Cornwall, and the three of us had a fairly alarming experience on the Black Isle a few years ago.) It may be that faced with the necessity of reaching somewhere to spend the night, and no obvious way of giving the field a detour, they will be prepared to take a few more risks. I just wondered, did you ever find yourself being followed around by a field-full of over-excited cows ? Or did they tend to be the uncurious /docile type?
Cows - I've never had a problem. The big difference between Spain and the UK, certainly in the mountains, is that they don't have fields. This might sound bizarre but it's non the less true. Cows and more often sheep are left to graze in unenclosed open spaces, often with a shepherd in tow who is helped by the huge Spanish sheep dogs. Unlike the UK, with its field system, it's unusual to find yourself in a confined space with cows.
