Head to the village of Saint-Cézaire-sur-Siagne and park in the free municipal car park on Chemin de la Chaux, via the D13.
(S/E) From the car park, cross the public garden, heading west, to reach the village centre, the fountain, Place de la Tour, then Rue du Docteur Aubin on the right to reach marker 10 at the end of this street.
(1) At this point, take the Roman road that descends towards the Canal de la Siagne and the Pont des Tuves.
(2) At marker 9, leave the GR® and turn right, heading north-west, onto the path that descends towards the Pont des Tuves and the Canal de la Siagne. At the canal, continue downhill, still heading north-west, to reach the Pont des Tuves.
(3) As you approach Pont des Tuves,take particular careunder the small waterfall, as the path is slippery at this point, on the edge of the Siagne. In the event of high water, it is virtually impossible to cross. After crossing the bridge, continue straight ahead for about 30 metres, then turn right at the three-way junction to reach the right bank of the Siagne. Continue north-west, following the river for about 2.7 km, to reach the Pont des Moulins bridge.
I have sometimes found it impossible to cross at the waterfalls at the Pont des Tuves. In this case, you have to turn back and walk about 50 metres to reach an old canal on the left (at the ruins). Follow it, then descend a small valley where a resurgence emerges. Then walk back down along the stream to the bridge.
"At worst, you might get your feet wet, but it's much less dangerous than trying to cross the waterfalls. I've seen people do it with water up to their waists: it's reckless."
(4) Take this path to reach the left bank of the Siagne and the GR®4. The trail climbs south-east to rejoin the Canal de la Siagne.
(5) Turn left and follow it north, then west for its entire length, about 2.8 km, to reach the D105. Cross carefully, then return to the canal, still heading north, parallel to the Chemin de la Foux.
(6) Leave the access to the D105 on your left and continue straight ahead to reach the water intake and the Grotte de la Foux.
(7) From this water intake, retrace your steps until you see the Route de la Siagne (D105).
(6) Take this road towards Mons (always carefully), then, after the first hairpin bend, continue north for 1.3 km to join the GR®49.
(8) After passing the power station (located below the road), continue for 250 m to reach a small car park along the road, where you will find a GR®49 marker on a telephone pole. At this point, a passage has been created in the metal guardrail, allowing you to reach the GR®49 and the Pont de Mons bridge below. Take this path (not easy to see) and descend to reach the bridge.
(9) After crossing the bridge, continue straight ahead. The path then climbs towards Saint-Cézaire.
(10) Continue straight ahead (east) and pass marker 22 to reach the old tarmac road to Mons. Continue along this road to a place called La Combe.
(11) The road climbs and curves. At this point, you can either leave the road and take the old GR®49 trail, which starts near a small lavender-blue gate on the right below, or continue on the road to reach the village and your vehicle (S/E).
