This page has some good links that I have found while trawling the internet for information on St James, the Via Podiensis and the Camino Frances. There are Confraternities in many countries that supply information on the Way of Saint James. They can help with background information, guides and maps. Through membership many offer additional services. I have listed a few in the links below.
There are some links relating to clothing and other equipment that be particularly useful for the route. There are many posts in many forums that mention particular items that were found useful on the Camino. I list some good forums here too. The idea of course is to travel lightly and travel simply. Knowledge is the lightest thing to carry!
