The second possibility is from the Rif. Drei-Zinnen-Huette, 2405m and below the north face of Paternkofel.
The third possibility for reaching the start of this ferrata is from a hut Rif. Comici, 2224m from the east side.
From the pass Buellelejoch/Forcella Pian di Cengia route goes first in south direction but soon turns to the east. You walk over the rocky and grassy shevles first. The route is very picturesque because of wild towers all around. Soon you cross the south face of Brodenknoten, 2668m and you reach a notch Forc. dei Laghi, 2584m.
From here a harder part starts. First you walk a bit up from the notch and then you come around a narrow ridge where is nice view to Paternkofel. From here you have to cross the airy shelves with help of iron cables. On one way there is also a small wooden bridge.
After the crossing you have to reach the notch Gamsscharte where other routes also come. From here you have to climb some 15 meters high vertical rock, which is well protected by iron cables. After this climbing you have only some easy climbing to the summit.
You descend by the same route or combine any other possibility.
