By taking the chairlift - Télésiège de la Cachette - you get to a path that goes up the length of the Télésiège de l'Arpette and leads to the Col des Frettes. At the top, take the left-hand path, which climbs gently up to L'Arpette (2 418m). You will have extraordinary panoramic views over La Plagne and Les Arcs ski areas, as well as the main peaks of the Haute Tarentaise.
