3 days (2 nights): Starting from Valfréjus (Modane)

East of Valfréjus, by road, follow the main road to the car park in Le Lavoir (1,920 m). From Lavoir, take the path leading to Refuge du Mont Thabor. After the water source, After the water source, follow the track to the right, cross over the river and continue as far as Plan (on the left bank). After Plan, veer right and follow the path that climbs SE towards Col des Sarrasins (2,844 m). When the weather is bad, be careful as this trail is not always well marked.
For the descent from Col des Sarrasins, follow the path heading east to Refuge des Marches (2,230 m). Like the ascent, this path is not always well-marked, but you will regularly come across cairns.

From Refuge des Marches (2,183 m), head along Vallon de Bissorte in a southerly direction until you reach Col des Bataillères (2,804 m), passing by Lac des Bataillères. You then reach Refuge du Mont Thabor (2,502 m, -300 m) after the Lacs Sainte Marguerite.

From the refuge, make your way down Col de la Vallée Etroite (2,434 m.). Cross over to the south side and follow the path leading to Lac du Peyron. Go around the rocky outcrop that dominates the lake to the left. You then reach Col des Méandes (2,727 m) where you can join the "classic Italian route". Follow the path up to the cross at the top of the mountain. The summit is just behind the chapel.
From the refuge, there's an alternative route to Lac du Peyron that avoids passing Col de la Vallée Etroite. From above Lac Rond, head southwards. Skirt Château Léger to the west. Then drop down to Lac du Peyron. This route is not well marked (there are a few cairns and a few paint marks).
For the descent, follow the same route to Col de la Vallée Etroite (2,434 m), then take the path down to the south-west to reach Lavoir.
