We have done it! 1,300km C2C down through Spain. Mainly following the Ruta de la Plata and other Pilgrim routes on the Camino Santiago. Our last 35km day bypassed another white hilltop town of Vejar de la Frontera before arriving back on the Atlantic at Barbate. The windmills described by Cervantes have been replaced with huge wind farms. Don Quixote would be even more confused.
Thank you all those truck drivers giving us space. Thank you car drivers for your patience. Thank you Spain!
