Trip
Set off on the highest trail in Savoie, France and even Europe! La Grande Sassière, at an altitude of 3,747 metres, is the highest peak in France and Europe accessible on foot. Located near Val d'Isère, this two-day trail running course in the Alps will allow you to admire the glaciers of Haute Tarentaise and Vanoise in a majestic, rocky setting.
On the first day, you will reach an altitude of 3,000 metres on the French-Italian border, before spending a restful night in a welcoming mountain refuge. The second day will be devoted to climbing the Grande Sassière via its classic route. A two-day trail running course for an unforgettable visual experience!
If you are looking for a slightly longer trail running course, our trail running course around Mont Blanc between France and Italy, the one in Chamonix or at Mont Rose are also available, in equally spectacular surroundings.
Program
Running time and breaks: Approximately 3 hours of running and technique
Elevation gain and distance: +1,000 m and -800 m; approximately 11 km
We meet at the Pont Saint Charles bridge after leaving Val d'Isère, then climb towards the Grand Cocor, just above 3000m, a first summit offering superb views of the Italian lakes, after skirting the Malpasset gorges and passing the refuge at 2300m, where you can leave your belongings. Return to the refuge via a loop, where a good meal in a warm atmosphere awaits you.
Running time and breaks: approximately 5 to 7 hours with breaks and technical points
Elevation and kilometres: + 1,500 and – 1,800 m; approximately 15 km
We leave the refuge in the morning to meet the minibus and head to the Sault dam, the starting point of the Grande Sassière trail. We then begin a long and beautiful climb of nearly 1,500 metres along the classic route to reach the Aiguille de la Grande Sassière, at an altitude of 3,747 metres. The high-altitude mountain environment will make you forget (a little) the effort and unusual altitude of this summit, which is accessible on foot. At the summit, the Aosta Valley from Mont Blanc to the Grand Paradis stretches out before you on one side, and the peaks of the Vanoise National Park on the other, along with their many glaciers!
In case of bad weather or difficult conditions, we will go to the Rocher de la Davie, which is 3,157 metres high, as an alternative...
Materiel
The high altitude and technical nature of the terrain require appropriate equipment, more so than for a more ‘traditional’ trail running course in the mid-mountains.
Bring a 15-20 litre trail bag for the day with enough space to carry a picnic and snacks.
Your guide will have a more comprehensive first aid kit in case of a more serious accident.

The Aiguille de la Grande Sassière surpasses the Swiss Barrhorn (3,610 metres) and its altitude of 3,747 metres makes it the highest hike in Europe. This climb is best done in optimal conditions between mid-August and early September, when summer temperatures have allowed the snow to melt completely.
Hikers are rewarded with an exceptional 360° panorama at the summit: from Mont Blanc to Gran Paradiso, via the Matterhorn and Monte Rosa. The national nature reserve surrounding the site is home to remarkable alpine wildlife, including ibex and golden eagles.
Winds can be strong above 3,000 metres, so it is essential to monitor the weather carefully before setting out on this legendary hike.
The normal route remains accessible without technical equipment for a short period at the end of summer, when the snowfields have melted on the summit section between 3,500 and 3,747 metres.
The ideal time is generally between mid-August and early September. During this window, experienced hikers can reach the summit without crampons or ice axes, taking the south-west ridge which avoids the Sassière glacier.
Conditions change quickly depending on the season. A tricky section on the rocky ridge at 3,250 metres requires particular attention. The condition of the terrain determines whether it is feasible: progress becomes dangerous on frozen or snow-covered ground.
If you want to hike the Aiguille de la Grande Sassière on your own, it is possible, but be careful as this is still high mountain terrain and very technical. The starting point is at the Saut car park (2,300 metres), accessible from Villaret du Nial via a 5.5-kilometre paved road, a few kilometres from the junction between Tignes and Val d'Isère. The trail starts on the right-hand side of the car park and climbs gradually through the mountain pastures of the Grande Sassière nature reserve.
The route crosses the Grande Combe before reaching a first plateau at around 3,100 metres, an ideal spot for a panoramic break. The final climb follows a series of steep switchbacks to the summit, offering spectacular views of the Lac de la Sassière.
The total route is 11 km there and back with a 1,450-metre elevation gain. Allow between 6 and 8 hours of walking depending on your pace. An IGN Top 25 3633ET map is essential for this adventure.
