The route starts from the car park on Boulevard des Fours, accessible via Rue des Mallonniers, at the eastern exit of Saint-Zacharie.
(S/E) Turn right, reach Boulevard Hoche, then follow the right bank of the Huveaune. You’ll come to a road.
(1) Turn left, follow the road for 150 m, then turn right at the junction onto Chemin des Nayes. Further on, stay on this track by turning left and following the signs for ‘Source des Nayes’. Continue straight on to reach a car park before the Ruisseau de Peyruis.
(2) Turn right, cross a small bridge over the stream and take the uphill track opposite. Follow this track until you reach the Route du Plan d’Aups. Cross it and climb, directly opposite, up a path that winds along the Ruisseau de Peyruis, which is almost dry at the moment (June 2023). The path, which does not always follow the IGN route, eventually reaches a junction; the path leading uphill from here goes to the Chapelle d’Orgnon, which is unfortunately on private land.
(3) Head straight down to the stream and continue straight ahead for 400 m past the stream, until you find a path leading uphill on the left.
(4) Follow this to reach a track. Cross it and head straight ahead, slightly to the right, along a well-marked path until you reach a Y-junction.
(5) Take a path on the left, which leads onto a cross-country track; follow this down to the left.
(6) Just before a bend to the left, take a path on the right, which does not follow the IGN route.
Continue for 400 m until you reach a small crossroads, then turn left. Join a track and turn right onto it, following it for 200 m until you reach a right-hand bend, after passing a meadow on your left.
(7) Turn left and you’ll soon reach a junction.
(8) Turn right, then, almost immediately afterwards, left. Continue straight on until you reach a track. Continue to the right along this track. After about 200 m, turn left onto a path. Continue along this path until you reach theGR® and follow it, turning right.
(9) Look out for the inconspicuous path on the right and head down into a wooded valley. Reach the Huveaune valley and follow theGR® to the left. Arrive at Avenue Jean Moulin and follow it to the left.
(10) Turn right towards the Huveaune, cross the footbridge and follow the right bank to reach the car park on Boulevard des Fours (S/E).
