This summit has an interesting, secured climb over the accessible ‘Galleria Paterna“. The ‘Frankfurter Wurstl’ marks the entrance to this ‘tunnel route’, which dates from World War I and is just a few minutes’ walk from the Rifugio Antonio Locatelli. A powerful torch is indispensable when walking through the galleries, although occasional light comes through the blown-out windows which also offer delightful views of the Sesto mountains. You leave the tunnel system at an altitude of about 2,520 m. Wire ropes show the way to the Gamsscharte (about 2,650 m). The final climb to the Monte Paterno runs along two well-secured wall ladders.
