From Rifugio Cibrario cross the Pian del Sabiunin flat westward, reaching for the moraine. Here a steep slope starts climbing southwards the 300 m. rise leading to a glacial basin. This is the relict of the previous Berta’ glacier (2900 m.), now a simple moraine crossed by little snowfields.
Now the slope is very light, and the plain may be crossed keeping close to the rock cliff descending from mount Testa Sula. A few turns of the path directly lead to Col Sule’ pass (3073 m). From here you can easily see the triangular shape of Point Costan, the Col de l’Autaret pass (this is our next destination) on its right side, and the small valley collecting waters coming from the eastern Autaret lakes. The second part of our treck takes place in this little gully.

From the Col Sule’ pass the path goes down a steep debris slope for an approximate 100 m, then the slope becomes smoother and a stony ground leads to an altitude of about 2800 m where, near e clearly visible boulder, we leave the
Costan Peak (3305 m) with the Autaret Pass (3071 m) path leading down to Colle Spiol and go up again (look for an sign pole) for about 30 m towards a small pass behind which is a snow-melting pool.
Pass the pool keeping on its left side, then go westward on a grassy ground, then look for path tracks leading south to a well-marked and visible stone-paved track. Take this track always going westward up to a hill from which you will a small lake and an old custom barrack which served as a refuge in the past Rifugio Moise.
