Dear Corrado,
thanks for this huge amount of wonderful pictures. I don't understand so much of your text, but I think everybody can follow your route very well. I just had some short time in the very North of Portugal in 2008. I just visited north of Porto the town Braga and the national park Peneda-Gerês crossbordering to Galicia. As I see now, there are a lot of routes and places worth to visit another time. I hope so to travel once more to Portugal in close future. I think you reached a lot of the towns by night as to find a lot of brilliant night fotos, which realize a warm atmosphere of your gallery. Even I think you had always a fine drink on tour for sleeping well.
