One of the Top 5 most beautiful Alpine treks, with 5 passes above 3000m and unconventional refuges, this isolated mountain range is steeped in atmosphere! The terrain changes constantly, from the bottom of the valley to technical overhead passes, panoramic summits above 3500m followed by magical descents, from high altitude glaciers to the shimmering torrents 2000m further down the mountain.
