As we drive away from Barcelonnette heading south towards Sisteron, the landscape gradually changes. The mountains are softer, less mineral, greener. The forests, fields and orchards tell us we are slowly entering Provence. Deciduous oak gives way to the shorter, evergreen oak and Provençal pine, and we see the first olive groves; the houses take on a paler shade of ochre, their roofs covered with terracotta tiles rather than flat stone.
We are taking the picturesque route, winding our way down on B roads through mountain passes and hillside villages. Occasionally there are signs for small, almost unknown, ski resorts such as Montclar, reminding us we haven’t quite left the Alps yet. This J-shaped itinerary involves going as far south as Dignes and then, as we reach the Durance valley, veering west and back up north to Sisteron.
From that point, we’re traveling partly on the ‘Route Napoléon’, the road which the former emperor, having escaped from Elba in early 1815, took to avoid running into the royalist troops in lower Provence on his way up to Waterloo.
