The Roads to Santiago - Route Details

Camino Francés
Puente la Reina-Burgos-León-Santiago

680km (approx)
Highest point: Cruz de Ferro 1504m
By far the most used route, and the one regarded by many as 'The Camino'. The Camino Navarro from Roncesvalles and the Camino Aragonés from the Somport pass combine at Puente la Reina, and then cross northern Spain to Santiago. The term Camino Francés is often used to include at least part of the Camino Navarro, typically from Roncesvalles or St Jean Pied de Port.
There is an enormous amount of info on the Camino Francés on the web; comprehensive guides, for example, on the Federation of Amigos del Camino de Santiago and Mundicamino sites.
The route is marked with yellow arrows. Nominally, the GR65 name of the Camino Navarro continues to Santiago, but there are no GR markings past Logroño.
