Debra and David walk the slopes of Spain's highest mountain range: the Sierra Nevada, underneath the hot sun of Andalucia. They take you through pretty whitewashed villages, along ancient mule tracks passing by water courses where butterflies and wild flowers bask in the sunshine. The couple then walks the colourful streets of Barcelona. They start by taking the modernism trail visiting Gaudi's Guell Park, Sagrada Familia and Casa Mila... then down the vibrant and entertaining Ramblas, through the beautiful Gothic Quarter and up to Montjuic. Debra talks to local expert Maria Albacar about Barcelona and it's fascinating history.
