My sister and I have rented a car for four days in the Basque region of Spain. We are currently in Guernica and have to drop the car off in Zaragoza. Any suggestions of cities we should visit or things we should do?
Anna, Bilaboa is an interesting city to visit, I hear. I knew a political science professor from there who encouraged me to come and visit, extolling the virtues. I haven't, but have always wanted to.
Hondarribia (also Fuenterrabia), past San Sebastian has a great restaurant, Restaurante Danontzat. Priceless memory of our trip for ten in our dinner club/travel group. Not on the way to Zaragoza from Guernica, but worth the detour.
