The fifth stage of the historic Haute Route leads from the Hospice du Grand-Saint-Bernard (2469 m) through the lonely mountain country east of the Great St Bernard to the Cabane de Valsorey (3037 m). The route passes through the Mont Vélan area and ends high above the Vallon de Valsorey, directly below the mighty Grand Combin.
With around 14 kilometres, 1670 m of ascent and 1110 m of descent, this stage is one of the most physically demanding sections of the historic variant. Several long climbs and descents, plus the steep final climb to the hut, make it a hard day.
