From Chambéry or Saint-Pierre-d'Entremont, climb to the Col du Granier to park.
(S/E) A few dozen metres from the pass, on the Entremont side, take an unpaved road (GRP® de Chartreuse) that heads west through meadows and then forest, leading to Les Ravines.
(1) Continue on theGRP® towards Les Granges de Joigny, without gaining much altitude. Pass these barns to reach a crossroads on the edge of the forest.
(2) Take the path on the right that climbs to the Col de la Gorgeat. Shortly after the crossroads, you will see some slabs of rock that the path follows. These slabs feature the imprint of a beautiful giant ammonite, and further on, a second, more deteriorated one. Continue the steady climb through the woods (GR® 96), which levels out near the Col de la Gorgeat.
(3) At the pass, turn left, heading north-west, onto a path that quickly leads to Pointe de la Gorgeat. The Pointe overlooks Chambéry and Lac du Bourget.
(4) Then retrace your steps back to the pass, avoiding the paths that branch off to the left and then to the right.
(3) Continue straight ahead on the ridge of the pass, leaving the path you took to climb up on your right. The path climbs a little, heads south-east before turning right for a fairly steep climb, damaged by rockfalls. Climb up to the ridge of Mont Joigny to reach its summit after a few gentler slopes.
(5) From the summit, the path continues along the grassy ridge towards the south-east, then descends slightly on the south-west flank to reach a crossroads.
(6) Continue straight ahead on a much less marked path, which passes near a pond and climbs slightly to the promontory of Pointe de la Bornée.
(7) From the Pointe, facing the Granier, retrace your steps to the previous junction.
(6) Take the path that descends to the left on the western side. The winding descent is quite steep but steady. Join a forest path (altitude 1336m) and follow it to the left. It descends southwards until it meets the carriage road from the start, immediately east of Les Ravines.
(1) Take theGRP® on the left, which leads back to the Col du Granier (S/E) via the same route you took on the way up.
