From a fairy tale fortress to the gentle Pyrenees, Rudy takes in the castles and peaks of this magical region. We tour the largest fortress in Europe, Carcassonne, and sample the local stew, Cassoulet. A gallop through the countryside takes in several romantic castle ruins and the artwork of Toulouse Lautrec. Then we head for high country and one of the world's natural wonders - a mountain amphitheatre with cascading waterfalls. Tips on driving in France, and mountain trails.
