From Passo Giau take CAI trail No.443 to the north, then leave the trail and follow the steep CAI trail No.438 on the left leading to the approach of the first section of this Via Ferrata. Along its short and not very exposed ledges you gently gain elevation with breathtaking views over the Ampezzo peaks: Cristallo, Sorapis, Croda da Lago, and Tofane.
Shortly, you reach the bottom of a narrow, vertical gully (the only hard section). From here, fairly good handholds, footholds, and a metal ladder will help you during the ascent. Once you reach the top of the ladder, a few more easy moves on steps of rock and few metres along the equipped trail lead you to the moon-like plateau (2500m) between Gusela and Nuvolao peaks.
Carefully follow the trail signs across the scree slope as far as a crest where the second section of the via Ferrata begins. After a demanding stretch, with the help of the iron cable and some iron ladders you will reach the top of Mt. Nuvolau (2575mt), near the namesake Rifugio. The unobstructed view is spectacular.
From the Rifugio, take CAI trail No.439 descending along the north face of Mt. Nuvolau, facing Mt. Averau (2649). This 30-minute walk will take you to Rifugio Averau, well-known for its fine cuisine.
Return to Passo Giau along CAI trail No. 452, time required is about 1h 15 minutes.
