The Mont Blanc region's must-do ski touring race

The Diagonale du Mont-Joly is a ski touring event, also known as ski-alpinism. Participants must climb snow-covered slopes using sealskins or special bindings, then ski or snowboard down.

Whether it’s the vertical kilometer or the mini DMJ, there will be something for every level:

The DMJ will start from the bottom of the Chattrix chairlift (Saint-Nicolas de Véroce) at 1200m, taking in succession the pistes of the petite and then the grande épaule to finish at the top of the l’épaule chairlift at 2135m, i.e. 935m of vertical drop.

The Mini DMJ, meanwhile, arrives at the top of the new Chattrix chairlift altitude 1660m with its 460m vertical drop.

To close the evening, a hot meal will be offered by the restaurant le Schuss at Plateau de la Croix to all competitors and accompanying persons in the form of takeaway dishes (meal included in registration, special rate for accompanying persons).

Mont-Joly, an emblematic mountain

Mont-Joly is a mountain located in the French Alps, more precisely in the Mont-Blanc massif, in the Auvergne-Rhône-Alpes region. It is part of the Pays du Mont-Blanc region, and is an emblematic summit for the village of Saint-Gervais Mont-Blanc (top of the ski area). The summit of Mont-Joly rises to an altitude of around 2,525 meters and offers hikers a 360-degree panoramic view of the Mont-Blanc massif, the Beaufortain, the Aravis, the Fiz chain and the surrounding valleys. It’s the ideal place to take memorable photos and admire the splendor of the Alps.
