After a couple of days tasting the gastronomical delights and seeing the sights we plan to take a train to the city of Le Puy where we intend to stay a day and a night.
Then our intention is to start walking (following the dotted light green line on the map) from Le Puy and head towards St Jean Pied [de Port] at the foothills of the Pyrenees.
This is a useful map which displays many Camino routes (there are more than 25). There is not such thing as walking the Camino but when people talk like this they are usually referring to the Camino Frances (St Jean Pied de Port to Santiago or parts of this).
Describing the Le Puy Camino, the Confraternity of St James says:
Terrain. Very varied but fairly strenuous and rarely flat, starting in the volcanic Velay region, with constant ups and downs, passing through the mountainous Aubrac plateau (at 1300 metres) before descending to the abbey at Conques. Continues through the causse (hilly limestone scrubland) to Cahors and then through undulating farmland to Moissac and on to the Basque country in the foothills of the Pyrenees.
The Camino Le Puy is about 750 kilometres in length so to get our total we'll add a few more kilometres for the days when we get lost and a few more for when our accommodation is off the beaten track.
This web page gives a good idea of the different stages and the kilometres between each.
