Passo Zube - Otro Valley Map

This is not a particularly technical or difficult route, but you need a good knowledge of the area and good visibility to complete it safely. It is great terrain for the novice ski mountaineer.


From the top station of Passo Salati, follow the Salati piste to the end of the first flat road, after the first steep section. Head off-piste on the left side of the piste, under the north face of the Corno Rosso. At the end of a long traverse you will start to climb along a narrow valley until you reach the Passo Zube, 2,874m (approximately 45 minutes climbing). Starting from the pass, in the direction of Alagna, descend the wide slope on the right side, until the Alpe Zube. Traverse under the Alpe Zube, first right then left, to avoid a big cliff. Follow the long gully towards the right until you reach the little village of Pianmisura. This section poses serious avalanche risk if there has been a lot of snowfall. From the village, traverse left following the track to reach a flat area and the village of Otro. The trail then enters into a dense wooded area leading to the village of Alagna. The last part of the path is narrow and often icy.



Slopes become slightly steeper at around 25-30 degrees.
