Start the hike from the Champ de Foire in Châtillon-en-Diois (parking available).
(S/E) Head north along Rue du Ruisseau. At the bridge, continue straight ahead, then cross the stream a short distance away and take the uphill path. At the top, follow Montée du Tricot to the right for a few metres.
(1) Take the path on the left leading to the Plateau de la Montagne du Glandasse (GR®91).
(2) At thefirst clearly marked bend, continue to the right on a path (no signposts or markings). Follow this path for a short while, enjoying some beautiful views (note the pretty passage over an old bridge).
As you approach the Forêt Giono area, you will come across numerous paths with Y-shaped intersections: at the first ones, take the left fork, then, after crossing a footbridge, take the right fork.
Please note that the path requires a little caution on a few short sections.
(3) Head to a pretty waterfall below and continue downhill, following the stream on your left (a refreshing spot when it's very hot). Shortly after the car park, continue along the track for about 200 metres.
(4) Follow a track on the right uphill. Just before you reach a private property, follow a path on the left to its end. Turn onto another path on the left.
(5) Quite quickly, take a path on the right: after crossing a small bridge, walk through a few gardens and join the Montée du Tricot. Continue left downhill, passing in front of the temple and the town hall. At a small square, pass under the porch of the belfry, then take Rue des Rostang to return to the starting point (S/E).
