There are four main Camino routes in France; in France they are called Chemin Saint Jacques. The only route I have walked so far has been the first ten days of the Le Puy Route, which I will list on a day
The Le Puy Route is also known as Le Chemin du Puy or Via Podiensis. This route starts in Le Puy en Velay and joins with two other routes in France at Ostabat near St Jean Pied de Port which they pass through and continue along the Camino Frances to Santiago.
The route is fairly tough going and quite hilly, it is harder than the Camino Frances and at 736km is nearly as long. The way marking on the route is the GR65 signs and there are very few Camino signs.
The Paris Camino Route is also known as the Chemin de Paris or Via Turonensis or The Tours Way, (the last really describes the route from Tours), – quite a few designations for a route that is not very popular at present and is said to still being re-built in parts. Like all of the routes in France this one also follows a GR, the GR655. The route is about 1,000km to St Jean, currently the distances are not exact.
The Vezalay Camino Route is also known as the Chemin de Vezelay or the Via Lemovicensis, the Latin name. Again joins the above two rotes just before St Jean and continues along the Camino Frances. The distance to St Jean is about 900km. Most of the route follows the GR654 but there have been efforts to re-create the original route by associations in France.
The Arles Camino Route also known as Via Tolasana or Chamin d’Arles. This route has its own association who are working hard to look after the route; I met a couple of them on the Le Puy route. This is the one main route that does not go to St Jean but joins the Camino Aragones and then this joins the Camino Frances at Puente la Reina. This route follows the GR653
There are many other routes in France, most of them are feeder routes to the above and the others in themselves can be very long.
