Built in 1983 by the Friends of the Mountain of Paularo, the ferrata to Mount Zermula climbs the north wall of this top of the Carnic Alps and ends with a suggestive ridge between trenches and positions of the Great War. It is a medium difficulty route, never extreme, on good rock rich in hooks, with a strong historical and panoramic value.

Starting from the Cason Pass of Lanza (1552 m): cross the road, a dirt road and then the 442 mark in the forest lead to the base of the north wall; a detritic valley cut diagonally leads to the attack (1833 m) in about an hour. Road signs →

From the attack you climb on rocks to the cable; the wall is steep but very attached, and you proceed in fun climbing between diedri, grooved plates and panoramic terraces. After a stretch on the path and a narrow nod, some more vertical walls and a detritic colatoio lead to the crest (about an hour from the attack). From here a ridge path exposed but comfortable, on the south side, leads to the summit cross of Mount Zermula (2145 m).

From the summit you descend along the panoramic Cresta delle Trincee, between walks and barracks, until you land on 442 and reach the Forcella di Lanza; the track 442a then returns to the Cason di Lanza (about 3h45 total). Those with favorable energy and weather can match the nearby Ferrata Zuc della Guardia.

In the Cason area of Lanza there is the Ferrata Zuc of the Guard, la Ferrata Crete Rosse e la Ferrata Senza Confini.
