La Thuile - Colle Crosatie

From La Thuile, follow the signs for Alta Via 2. Continue along the asphalt road to a bridge from which the dirt road that runs alongside the stream starts. When you reach the asphalted road, take the path that leads to La Joux on the right, which leads to the waterfall trail that leads to the Deffeyes Refuge (2500 m). Refreshment and control point.
From the Deffeyes refuge continue towards the Passo Alto (2857 m). From the hill you go down first on stony ground, then on path, up to the Promoud mountain pasture (2022 m). Refreshment and control point. Continue following the signs for the Colle de la Crosatie (2838 m), which is reached by following the path along the river, up to a valley of debris and then to the stone that ends at the top with large stone steps.
