We’re planning to venture to Santiago de Compostela in the spring. We have a Hymer and a Smart car. Until recently, we towed the car by means of an A frame, but have just bought a Woodford trailer to ensure we are legal in Spain. Any advice on the best route? Should we take the coast road or the Camino Francés through Pamplona, Burgos and Leon? We haven’t even decided whether to cross to France or Bilbao or Santander yet. We’ve heard reports of very rough crossings.
