Just got back from Pyrenees last week forget travelling through France if you only have a week get ferry to Santander and then cross over to the Picos area in Spain then make your way over towards Andorra on the Spanish side and back on the French side personally prefer the Spanish side.Have done the trip using Santander ferry going, then travelling back through France to Le Harve the money spent on fuel and stops on return journey, use it towards extra ferry cost and spend extra time in the Pyrenees you will not regret it.
