In the summer, we are driving from La Rochelle (France) to Lisbon (Portugal) (long story). Our DDs are 13 and 11. It's around a 13 hour drive so we're going to split it up into two days. Is anyone familiar with the part of northern Spain that we'll be driving through? Do you have any suggestions of where to stay en route or particular highlights of places to visit to break the journey? TIA.
