Looking at the cliffs in the far distance, the route starts on the left hand side - going up a wide arching fault line before stepping across to travers on the right hand side of the groove.
Once at the top of this buttress, there is a long walk right, under either the cliffs above until the path / Ferrata starts again.
Ultimately it takes the left hand upper butters, at a break the left again up the final head wall.
