The way to Compostella has been trodden by millions of pilgrims seeking salvation in the great Cathedral of Santiago, resting place of St James, after a long, hot and dangerous journey over the mountains, arid plains and rich countryside of Spain. Robin and Louella Hanbury-Tenison made their pilgrimage in a traditional way on horseback often over long-forgotten tracks and in the process discovered more about the people and the country than any motorist could know. The way was arduous but not without its wild humour. In the process Robin came to experience a true "green pilgrimage", an ecological equivalent of the search for religious faith in medieval man.
