This itinerary fits the north into six days by linking Haut-Asco – Ciottulu di i Mori (15 km, 1,800 m of ascent) and Manganu – Onda via Petra Piana. The long Golo stage, Ciottulu – Manganu, is done in one go. The last day is short and reaches Vizzavona around midday.
It is aimed at very well-trained hikers who are used to boulder fields and chain-equipped sections.
