Échelle de randonnée (SAC)

Les randonneurs et les grimpeurs connaissent probablement les marques colorées que l'on peut toujours voir sur les chemins et les itinéraires de montagne. Il s'agit d'estimations du niveau de difficulté du chemin ou de l'itinéraire.

La classification des niveaux respectifs remonte à l'échelle SAC, qui a été développée en 2002 par le Club Alpin Suisse (SAC).
