The source of the river Hasel

At the last right turn, ascend via a small footpath on the left which passes the source of the river Hasel, reaches the Altmatt pass, between the Grassmann (987 m) and the Noll (990 m) peaks. From the pass, head south to reach the ridge of the Rocher du Mutzig at the Narion pass (Cabane des juifs), on the path.
