To help future pilgrims decide which route to follow when making their journeys to Santiago the Confraternity has just published a new guide in their Practical Pilgrim Notes series entitled Which Camino?
This 56 page guide contains short articles on 22 caminos written by CSJ members who have walked or cycled the routes concerned and know them well, in many cases by our own guide writers. It provides information on the routes themselves, length, terrain, places of interest along the way, accommodation and services and the availability of maps and guide books.
