Park at Pré Matheron, located near Château d'Ancelle.
(S/E) Set off along the meadow between the small path on the left and the road on the right. Once at the end of the meadow, enter the forest and continue heading south-west. Pass a first clearing and reach a small bridge.
(1) Turn left onto a narrow path that climbs alongside a second clearing. At the top, keep to the right towards the next clearing. Go past it to cross the small wooded slope that follows. Reach a crossroads of paths.
(2) Turn left onto the better-marked path and follow it to its end (overlooking the Collet d’Ancelle road). Tackle the steep climb in tight hairpin bends – this is the Roustanis slope on the map – to emerge from the forest.
(3) Climb up to the left across the meadow; the path soon runs between the forest on the left and the fence on the right, which follows the ridge line. Pass the junction of paths, then at the next intersection you will see small yellow signs.
(4) Turn right and follow the somewhat winding ridge line to go round the vegetation and large boulders. Reach the summit of Saint-Philippe.
(5) Begin the descent by following the ridge line straight ahead.
After a final detour around the trees, pass between the rocks on the left and you will soon emerge above the ski run. Join the ski run.
(6) Turn left and follow the track, keeping to the red and white markings ofthe GR®50. You will reach a crossroads near two chalets.
(7) Take the path on the left, which climbs gradually in several stages. Turn right at the next junction; the path now descends to a hairpin bend. Turn left and continue to the Pré Matheron car park (S/E).
