There are many routes that can be walked on the Camino de Santiago. The most popular and populated route goes from St Jean Pied du Port in France across the top of the Iberian peninsula to Santiago de Compostela. This is the path the I have walked the past 2 years. It is approximately 800 kilometers or 480 miles. This coming year I will be starting in the southwest of Spain at Sevilla and walking to Salamanca which is about 340 miles north.
