Explanation
This challenging segment leads from Gfrill / Cauria (1,330 meters above sea-level) via the hamlet of Gschnon / Casignano and the Cisloner Alm and to Aldein (1,200 meters above sea-level). At the beginning, the route is uphill via the Gfrill Saddle until you reach Gschnon (option for rest-stop, food/drink, and overnight lodgings). From there, you will continue over the asphalt road uphill until you come to Mühlen / Molini (again: option for food/drink and overnight lodgings). After that, it's a rather steep path up to the Cisloner Alm. From here, you will proceed downhill until you reach the Aldein Bridge (known as the "Little European Bridge" when built back in the 1960s). This is a good spot to make a rest-stop (lodgings also available). You can then continue via Holen / Olmi until your come to Aldein / Aldino.
