This trail takes you across France, from the provence in the East to the Atlantic coast. In between you pass the beautiful Montagne du Lubéron and the famous Mont Ventoux. Another famous place is the Gorges du Verdon. Further west you cross the Rhône and walk towards Clermont-Ferrand and the dead volcanoes and Puy-de-Dôme. The crossing of the high plains of Auvergne is a special thing. Next is the region of Limousin and finally the Atlantic.
Be aware that the region around the Lubéron might be closed all summer (july-august) due to risk of forest fires.
