The calade made with the Lycée Professionnel des Métiers de la Montagne.

This portion of the trail, whose work was completed in 2013, is the fruit of a valuable collaboration between the Park workers and the “Lycée professionnel des métiers de la montagne” (vocational school of mountain trades) of Saint-Michel-de-Maurienne. For three years, the pupils of this school, supervised by the workers, used the ancestral techniques of the calade to refurbish a portion of the trail that the particularly unstable terrain was damaging each year.
