From Wim's travel report:
After a stretch of motorway from Marseille I head back towards the coast via a road that consists entirely of bends.
Not far from OB the GPS says to turn left here and I end up on a farm.
Back and forth on the road does not seem to offer an alternative and I decide to eat something first.
I take a good look at the map of the GPS and see a few lines that go towards the end point (= OB).
I am close to such a line and park the car there.
I had seen a cyclist riding on that path earlier and since the distance is still more than a kilometre I take the folding bike.
Cycling and walking I reach OB. The way back down went very quickly!
