Hi

Have done most ways through France.

Best advice. Take a Sat Nav, for use when the French put you on a diversion, and forget that you need more than one sign ...

The route via Bordeaux, and the tunnel at Somport is good - use the N10, and not up and down till the Spanish side - then take new motorway to Zaragoza ( some one said 3 hours from here ) and then back via Caspe. about 1000kms from Dover, and low tolls ( just some around Boulogne unless traveling at night then take the local roads not the motorway )

sorry for the speelingsa - a cat is helping me typeee
--- must be the m,ouse lol
