I have downloaded the KMZ files from http://www.mapacaminosantiago.es/jacobeoebro/01-deltebre-santcarlesdelarapita.htm and translated them to a .gpx format that can be more easily imported into standard GPS units. This has been tested using both Garmin Basecamp and Garmin Mapsource, and they have been successfully transferred to a Garmin etrex30.
