Tracey Hi,
An awful lot depends on where you are coming from and where you are going to.
Spain is an awfully big country!
Take a look at the viamichelin website, (click the highlighted link), and input your UK hometown and destination address and see what it come up with. I would suggest using the viamichelin 'Recommended Route' The good thing about this website is that it is updated regularly.
Specifically if you are heading towards the CDS or CB its almost impossible to avoid some contact with Madrid, but the city is surrounded by a series of concentic ring roads, the outermost of these is the M50 and this is the one to use rather than the M30 which routes through central Madrid and can be a nightmare. The M50 routes to the east of Madrid between Barajas Airport and Torrejon Airbase and is the preferred route of most people making the trip.
Brittany Ferries operate Portsmouth and Plymouth to Santander in Northern Spain and the journey time is 30 hrs. They also operate Portsmouth to Caen journey time 6 hrs but you then have most of France to drive through as well as Spain. I would suggest that unless you live in Essex or Kent, Dover is best avoided as a jumping off point (this include the Chunnel) since the routes South from Calais include Paris which is definitely not for the faint-hearted.
Driving all the way from Northern France to the CDS / CB is best done over two or three days; my suggested stop-off places would be near Bordeaux and Madrid.
Just to add to Lorraines list of essentials...make sure your MOT and Road Tax are fully valid.
You must carry with you originals of the valid vehicle documentation. I would suggest you get breakdown insurance too.
Also you will need two breakdown triangles.
If you breakdown or if the police stop you for any reason and invite you to get out of the car, make sure you put your hi- viz vest on before exiting the car; its an automatic fine if you dont.
Just remember the steering wheel of your car is on the wrong side for European driving so when you're on the road, plan your moves ahead of time!
Take your time, take care and enjoy the trip!
