Park in the centre of La Giettaz, near the fountain.
(S/E) From the fountain in the centre of the village, take the small paved road to the left of the bar, which climbs and joins the Route du Col des Aravis further up, which you should take on the left. About 200m further on, turn left onto the small road towards Foiroux. Pass a wayside cross and continue for another 250m.
(1) Leave this small road and take a gently sloping path on the left, crossing the Torrent des Aravis on a bridge. Follow a steep, damp path, first going up into the forest, then along a small stream, crossing it and continuing uphill to reach a junction (signposted La Stamochère)
(2) Take the left fork; the right fork will be for the return trip. Continue along the path that crosses sloping pastures, then descend to cross the Ruisseau de Foiroux.
After the ford, climb up a winding path through the forest, which is not always well marked, especially in a marshy area after a ramshackle chalet. You will emerge in the Blanchet mountain pasture (signpost).
(3) Follow the path on the right across the meadow to reach the forest. Climb back up into the forest, then begin a long descent, passing a first chalet, then a second, until you reach the Sesteneret intersection (signpost).
(4) Ignore the path coming from the left and climb up alongside a torrent (the Nant de la Coufa). You will come to a wider path at a group of buildings: Les Stapssets. Turn left.
(5) Turn left, cross a stream and shortly afterwards climb up the slope to reach a wide track called Route des Montagnes.
(6) Go up this wide track, keeping to the right, pass a farm building on a bend, then continue on the flat to the next intersection, signposted Chalet du Curé; the chalet is at the top of the hill.
(7) With your back to the chalet, descend along a small road towards a group of buildings and, just before you reach them, turn left to join the Route de la Montagne.
(8) Continue downhill, pass Plan Rebord (chalet-restaurant) and reach Psamo.
(9) After the buildings, turn right and go down the path.
(2) Turn left to return to the car park (S/E) by following the same route you took on the way up.
