We leave Vielha and, after crossing Gausac, we join the Camin Reiau, an ancient path that connects the villages of the Val d’Aran. The route runs parallel to the Garona river along wide paths and shady stretches, where the trees form a tunnel of vegetation. The forest is dense, full of birch, hazel and beech trees, with the constant sound of the river nearby. The terrain is gentle and very pleasant until Arròs, where we cross the river to begin the climb towards the Varradòs valley.
