The course starts and finishes in the same place as number 2. Starting from the La Ruchère Nordic site, you begin in the forest to the right of the entrance to the cross-country trails.
The wide trail winds its way back to the cross-country ski trails, with narrower sections
undergrowth. You skirt the edge of the communal forest, then cross the tracks to join the wide path to the Riondettes belvedere. The view over the valley is splendid. Go back a few metres and take the right-hand loop with a short climb that continues towards the Col de la Sariette. Continue left to join a wide track that climbs steeply to the Rochers de Pertuis ridge. You then descend to the Arpison meadow, which you climb up to reach the Belvedere and its exceptional panorama. Go back down the meadow and turn left onto the cross-country track, continuing downhill to join trail no. 2 at the end of the Riondettes meadow. Forests and meadows finally bring you back to the foyer, with a last sumptuous view of the cliffs of Les Eparres and Pas Dinay.
