Ferrata reachable from Valmadrera. The progression takes place on a wall with some exposed sections, traverses on cable, but with well-visible metal holds. In the sections where the holds are further apart, the rock still offers good grips. In the second part, there are some ledges useful for resting. The panorama spans Valmadrera, Lake Lecco, Monte Barro, Lake Pusiano and Annone, and Resegone. In about 45-50 minutes, including the approach, you reach the summit of Corno Rat (924 m a.s.l.)

The climb from Forcella dei Corni to Corno di Canzo Occidentale follows a section classified EE, with passages on rock and grass and some easy climbing sections; it requires a surefootedness and attention, especially in case of wet ground and rocks. Great place to admire the surrounding panorama.

This via ferrata is considered grade D (difficult). There are many stirrups, so if you're well-trained, it's less difficult. It's definitely very exposed.
