The Post Office (Correos) in Spain have a website in English for the Camino at http://www.elcaminoconcorreos.com/en/ which includes some short downloadable information on the Caminos ( http://www.elcaminoconcorreos.com/en/downloads ) and information about their backpack transport ( http://www.elcaminoconcorreos.com/en/rucksack-transfer ) which we have used to transport my Mum's backpack and found to be cheaper than anywhere else that we looked as well as being reliable.
