On the D 901 coming from Les Vans towards Saint-Paul-le-Jeune, park on the right just after the Pont du Granzon bridge next to the Resistance monument.
(S/E) Take the straight path that heads west from the monument towards the mountain until you reach the first crossroads.
(1) Take the path on the right that climbs up to Mas du Granzon. Cross the submersible bridge over the Granzon, leave the entrance to the property on your left to reach the start of a discovery trail on the left.
(2) Follow this path to the left without entering the property, gradually approaching the bed of the Granzon stream.
(3) Pass to the left and close to the Résurgence de la Grille. The path then descends almost into the stream bed, heads north, crosses the stream and follows a series of meanders to the west on the right bank. After the Fontaine du Vedel, continue along the stream bed until you cross the GR® 44A (clearly marked in red and white).
(4) Take the GR® on the right uphill. Reach an olive grove on the left and continue to the road. Leave the GR®.
(5) Follow the road to the right and continue to a crossroads with a triangular traffic island (elevation 259).
(6) Take the road on the right downhill at the start. Continue along it after passing a few houses until you reach a large three-way junction (on the map, a cross is marked on the left, but only the base remains, looking like a slightly leaning menhir).
(7) Turn onto the wide path on the right that leads back to Mas du Granzon.
(2) Take the same path back in the opposite direction until you reach the Resistance monument (S/E).
