Starting point: a car park in the centre of the hamlet of Vaudanoux, in a square with large trees, accessible from the Route de Saint-Maurice-d'Ibie (D558).
(S/E) Leave the car park and, turning left, head back along the access road to the hamlet. Follow it for about 600 m. At the foot of a hill with clearly visible dry stone walls, just after a bridge over a dry stream, look for a wide path climbing up to the left.
(1) Leave the road and take this path. Pass two hairpin bends, then a ruin, and arrive at a crossroads with several paths.
(2) Take the path furthest to the left, slightly set back. Pass less well-defined paths on your right and left, and reach the crest of the hill after a final fairly steep climb.
Turn left onto a wide path heading south, which gradually narrows to a trail after passing between two dry-stone walls. You’ll come to a wall separating two branches of the trail at the foot of a large oak tree.
(3) Take the path on the left, leaving the wall on your right, and continue heading south.
Note: just past this point, as mentioned in the reviews, a large tree has fallen across the path. I went back there recently to check. You can get round this by going left through the undergrowth (there are visible tracks) to a dry stone wall, which you follow for a few metres before rejoining the path.
Continue down through the undergrowth to a more open clearing where you’ll find a path running perpendicular to the main route.
(4) Turn left. Follow this path (north-east) leaving two paths coming from behind on your right and reach the car park after crossing the hamlet (S/E).
