Hi Paul,
I was in a small place (La puebla the los infantes) somewehere in the middle between Sevilla and Cordoba. Have a look at this website: http://www.fincaparadies-andalusien.de/
I found several Malpolon, Natrix, Coluber and Coronella. Unfortutately no Vipera's.
If you want to visit Spain I advise you to go in spring. Not in the summer. It was 46 degrees centigrade in summer and very very dry!
Anyway, take your camera with you!
Gilian
