Mountain Hikes around Réserve Naturelle de la Grande Sassière
The hike to the Aiguille de la Grande Sassière (a 3,751 m high mountain in the Graian Alps) is easy. The west and east of this part of the Alps form the watershed between the Rhône (Isère) and Po (Dora Baltea) rivers, which also forms the border between France and Italy. Climbing to the summit also offers a unique opportunity to see a glacier and two glacial lakes. If you're in the area, don't miss this breathtakingly scenic hike in the Vanoise National Park!

The Aiguille de la Grande Sassière, or often simply the Grande Sassière, is a 3751 m high mountain in the Graian Alps, located south of the Mont Blanc group, or more precisely just southeast of the Petit Saint Bernard Pass, on the ridge that separates the west and east of this part of the Alps and forms the watershed between the Rhone (Isère) and the Po (Dora Baltea), and across which runs the national border between France and Italy. This ridge also forms the seam between the Aosta Valley and the historic Savoy in the Savoie department and, a few kilometers further southeast of the mountain, between the two adjacent national parks of Gran Paradiso and Vanoise, at the height where, within these protected areas, passes connect the north and south sides of the parks: to the west, the Col de l’Iseran Tarentaise (Isère) and Maurienne (Arc Valley), to the east of the Colle del Nivolet the Aosta Valley and the Orco Valley (Piedmont).

Our plan was to climb the summit with our bikes on our shoulders. As there was still a lot of snow and some light climbing was required, we parked our bikes along the way. I recommend the Aiguille de la Grande Sassière for hikers but not for bikers, as the descent is partly doable but not worthwhile.

From Les Brevieres, this mountain is a real challenge to your fitness, as you have to overcome over 2200 meters of altitude. You will be rewarded up there with a magnificent view of the great 4000-meter peaks in the Alps. My tip for this tour is to take crampons in your backpack; they were really needed on the last 200 meters as there was a lot of snow, which is possible at this altitude at any time of year.

As its name suggests, this charming little stream is located in the Grande Sassière nature reserve, at the foot of the eponymous needle. It connects the Sassière lake and the Saut lake in the magnificent alpine environment of the Tarentaise.

Indeed, a magnificent portion of trail, as beautiful going up as going down, to regain strength before the final assault to reach the summit.

The reserve boasts a variety of impressive natural features. You can explore the picturesque Sassière Lake and Lake du Saut, which is created by a small dam. The area is also home to the Sassière stream, connecting these lakes, and offers views of the Sassière Glacier. The diverse geology includes quartzites, limestones, and gneiss, contributing to its rich alpine ecosystems.
The reserve is a haven for alpine wildlife. You can frequently spot marmots, especially on the Sassière plateau, and hear their distinctive whistles. Ibex (bouquetins) and chamois are also common mountain ungulates in the area. Keep an eye on the skies for birds of prey like golden eagles and bearded vultures (gypaètes barbus).

Absolutely. A popular and accessible option is the 2 km path leading from Parking du Saut directly to Sassière Lake during the summer months (July-August).
