This leg is the highlight of the route, setting off from Preda via the Albula Pass to the southern tunnel portal. The mountain hiking trail passes by the crystal-clear Lai da Palpuogna lake, climbing up to Alp Weissenstein (known as Crap Alv in Romansh) and onward to Fuorcla Crap Alv. This is followed by a steep descent into the Val Bever valley until you reach the idyllic Spinas, your destination for this leg.
