The official stages of the north, with an extra night at Castel di Vergio: the longest stage of the route, Ciottulu di i Mori – Manganu (25 km), becomes a half-day descending the Golo valley, followed by a fine day via Lac de Nino. No day exceeds 17 km.
It is the ideal itinerary for discovering the most alpine part of the GR20 while saving energy for the technical sections, notably the Pointe des Éboulis between Haut-Asco and Tighjettu.
