The Camino de Santiago is a five hundred mile walk across the north of Spain to the cathedral in Santiago de Compostela.  People do the pilgrimage for a variety of reasons.   For me it was thinking about my future and the direction I wanted my life to go.  It was the impetus for starting  to WWOOF.  Here is a link to the web journal I wrote while walking the Camino in the summer of 2012, http://www.trailjournals.com/entry.cfm?trailname=13826
