This trail starts at the top of the village of Vercorin and takes you to discover the peaks of the region. Follow the route de Tracuit and then the upper reaches of the vallon de Réchy. You'll reach the sublime Lac du Louché before continuing on to the Becs de Bosson at an altitude of 3149m. It's not unusual to see snow here, even in summer! Don't forget to enjoy these lunar landscapes during your run.
The second part of this route takes you over Roc de la Tsa, Roc d'Orzival and Brinta, before descending to Mont Major and finishing at Crêt du Midi.
But be careful! This second part is more technical because of the scree along the way. The path is equipped with chains, but can be vertiginous.
