From Jaman station (1739 m), descend briefly into the valley before zigzagging up to the base of the broad northwest-facing cliff, reaching the via ferrata start around 1840 m. Alternatively, from La Perche station (1795 m), follow the track and cut off just before the tunnel, then traverse scree along the cliff base for about ten minutes to reach the same start point.

The route begins abruptly with a steep 50 m vertical-to-overhanging wall (K5-) that quickly pumps the forearms before easing off. A rope bridge crosses into the Gouffre de Niton cave, offering a good rest point, followed by another strenuous (K5-) section leading to a diagonal ramp requiring continued arm strength up to a grassy band. From there, climbers can either exit via a vertical corner (mandatory between May 1 and July 1 due to nesting birds) or continue on the harder variant, descending along the grass band, ascending a slab, traversing an exposed second slab, and finishing on a demanding overhang (K5+) near 1990 m.
