(S) From the Carrozzu refuge, follow theGR® trail towards the south-west. After a short section equipped with chains, you will reach the Spasimata footbridge, which allows you to cross to the left bank.
(1) After the footbridge, theGR® climbs up large rock slabs overlooking the stream. Take care in wet weather. Some sections are equipped with cables.
The trail then continues to climb through alder trees and scree from an ancient glacial valley. The trail then becomes a little steeper along a rocky ridge, leading you to Lake Muvrella (1,860 m).
(2) The climb between Lake Muvrella and the pass of the same name is very steep in a corridor with large boulders. Cross over to the other side, on the western slope, and reach Bocca di Stagnu (2,010 m).
(3) The descent is quite steep and quite long, initially over open terrain, which allows you to see the destination of the stage, then continues through old pine trees to the Asco Refuge (E).
