Hi Gary
I have driven a number of times and the best route is via Somport Tunnel but this time of year I would probably avoid it with the snow see below option.
Calais - Saint Quentin - Reims - Troyes - Dijon - Lyon - Orange - Montpellier - Narbonne - follow AP 7 down Barcelona - Valencia through to La Mata. This route is possibly the best as its motorway all the way and is kept clear.
Calais - Abbeville - Rouen - Le Mans - Tours - Poitiers - Saintes - Bordeaux - Biarritz - San Sebastian - Pamplona - Tudela - Zaragoza - Teruel - Valencia and onto La Mata. This route may not be as weather friendly but good for summer use going via Pau and Somport Tunnel.
Regards
Andrew
