Luberon The Luberon is a forest that borders the southern Vaucluse, a large natural park with castles and medieval towns. There is a 146 mile cycle route around the massif and the Parc Naturel Régional du Luberon, marked in both directions. It follows narrow lanes through picturesque villages, avoiding busy roads, which are placed mostly on top of hills, so it climbs at times giving good views along the valley. We followed it for the day going east through Oppede-le-Vieux, Menerbes, Bonnieux, Apt and stopping at Le Boisset to camp. The path in the photo is on an old railway track.
