Departure from Gréolières, marker 30 along the D2 at the eastern entrance to the village.
Take theGR®4towards the Cime du Cheiron.
The path passes by the ruins of Hautes Gréolères. Old buildings, ancient castle, Sainte-Pétronille chapel.
Climb up to marker 193.
(1) Turn left (west) and continue towards Cime du Cheiron. The path passes easily through the Barres du Cheiron and takes you to a rocky mound topped with two crosses (one wooden and one smaller iron cross). If you are sure-footed, you can easily climb the rocky outcrop.
TheGR®4then takes you to the small pass of Barri (marker 194)
(2). Leave theGR®4and turn right (east) onto the path towards the Cime de Cheiron. From this point, follow the yellow markings, which are not always visible. Fortunately, cairns help you to find your way. Between the cairns and the yellow markings, the path is still fairly easy to follow. A huge monolithic cairn invites you to correct your direction towards the north, then the path reorients itself towards the east and the summit.
(3) The Cime du Cheiron (1,778 m) consists of two mounds, one topped with an antenna and the other with an orientation table. This is the highest point of the hike, and the view is fantastic.
To the north, you can admire all the peaks of the Mercantour and even those of Italy (Argentera is clearly visible). To the south is the coast, where the blue of the sea and sky merge. The southern slope with its spectacular rocks is worth a look. To the east, like a roller coaster, is the ridge that we will follow.
It goes up and down constantly, even though the overall gradient slopes gently as you progress eastwards. You climb 7 or 8 peaks, including the Cime de Jérusalem (4) (1,768 m) and the Croix de Verse (5) (1,706 m). It should be noted, however, that the climbs are not very difficult, so the route is fairly easy to follow.
The route is marked in yellow (traces that are easy to lose) and cairns, but the direction along the ridge is so obvious that it is impossible to get lost. You can even venture onto the rocky slopes to admire the descents into the Adret du Cheiron. The yellow markings are easy to find as they are kept at a distance from the edge of the ridge.
From bumps to grassy hollows, the yellow markings and cairns lead to marker 147 and immediately to double marker 146
(6). Leave the ridge and descend to the right towards the village of Coursegoules via 26 hairpin bends to marker 13a.
(7) Turn right towards the west, in the direction of Gréolières, for a fairly flat or even downhill return. A wide track leads back to the start.
(8) Be careful not to be tempted to descend towards Saint-Pons. (Otherwise, you would have to climb back up to marker 179). So stay on the wide track.
(9) At Font Roubaud, find the yellow markings and follow them to marker 192.
(10). Descend to the left towards Gréolières via Clos d'Antony. The path leads back to the starting point (marker 30).
