Departure from Col du Frêne, reached from Les Bauges via Sainte-Reine or from Saint-Pierre-d'Albigny. Car park on the Bauges side of the pass.
(S/E) Almost opposite the car park, take the path heading north towards the forest. After a wide circular loop to the left, it arrives at a series of clearings, all of which are passable in snow. Continue climbing south-west until you reach a crossroads.
(1) Most tracks turn right (see alternative route), but continue straight on south-west, climbing through the forest until you reach the edge of the cliffs overlooking the Combe de Savoie in Cra.
(2) Climb to the right up the ridge via a steep slope, then the slope levels out and you will find yourself in the forest overlooking the Bois Saint-André.
(3) Turn right to continue climbing the ridge, now heading north, until you reach some meadows. Stay on the ridge, which crosses a copse and descends slightly to the top of Pré Pignon. Continue a little further along the edge between the forest and the meadow until you reach its upper limit near a fence.
(4) Climb straight up into the forest on the left to rejoin the ridge trail, which climbs steadily until it leaves the forest in a setting of mountain pastures and then reaches the summit of Mont Morbier (or Morbié).
(5) Descend due west and climb back up opposite Mont Pelat (arrival point of the Aillons chairlift).
(6) Follow the ridge north-east (towards Mont de la Vierge) and after a good hundred metres, turn right into the valley, heading east, cross the ridge from Mont Morbier and continue downhill through the Plamand meadows until you reach a good pastoral path descending from Chalet de Margerie.
(7) Take this path to the right and descend along this gently sloping path with wide hairpin bends, some of which can be cut across if you can see clearly. At the bottom of this long descent, there is a junction with a path leading up to the right towards the chalets of La Cornue.
(8) Continue down the path, which turns left towards Routhennes. Shortly after a bend, turn right onto a forest path that is circular and heads back towards Routhennes.
(9) When you reach a field, leave it and cross the flat field towards the south-east until you find a forest path that descends slightly.
Continue along this path, ignoring the paths leading downhill to the left (which take you too far down), and keep heading south-east, with a few slight ascents, to rejoin the uphill path at a bend. Take this path to the left to return to the starting point nearby (S/E).
