Carozzu refuge, is where one of the scenes in the famous French film ‘Les Randonneurs’ was filmed. Shortly after you set out, you come to a swing bridge. This is a great spot for a swim. Once across, you head up river all the way to a small lake, called Muvrella. A steep narrow corridor comes out at Bocca Di Stagnu. You stay on the high ground until you see below the car park and buildings that comprise Ascu Stagnu.
A steep descent that will take you a couple of hours leads to a forest track, where there is a row of unusual ski chalets bordering just above the ski station, your night stop.
