Parking is easy and free at the Castagniers car park, 50 m from the start of the walk.
(S/E) From the car park, head down towards Route de Castagniers, cross it and take Chemin de la Florette northwards, towards Le Gressier, until you reach a Fork in the road.
(1) Turn left onto a track called Chemin de la Forêt, which descends towards the mills via the Porquier. Follow this track down and turn left again onto a path heading north-north-west into the Porquier ravine.
(2) Cross the Ruisseau du Porquier and head back up the ravine to join the Chemin du Grand Bois.
(3) Follow this road northwards; it is a one-way road in the uphill direction. Pass two hairpin bends on this road and continue until you reach a wide track at a left-hand hairpin bend.
(4) Take the Chemin Forestier du Descaus Inférieur eastwards, and join the Chemin de la Plane Soutrane after crossing the Ruisseau du Porquier for a second time.
(5) Pass a cross on the left. This cross was restored by the Cistercian nuns of the nearby Monastery of Notre-Dame de la Paix. Continue due south on the Chemin de la Plane Soutrane and join the Route de Castagniers, following it for 50 m, before turning right onto a tarmac path that passes under the road.
(6) This tarmac path descends gently and joins the Chemin de la Florette; follow this due south to reach the Fork in the road with the Chemin de la Forêt.
(1) Turn left and you will soon reach the Castagniers car park (S/E).
