Route starts at Ücia Pederü. It goes up to the hut Lavarella via the hiking path and further on to summit Heiligkreuzkofel and Zehnerspitze (only beginning of the via ferrata, not the summit itself). Back that way to Forcella di Medesc and up to Piz Lavarella via the north face. Some climbing UIAA 1 to 1+ is needed. Both summits must be reached (main and west summit). Further on down the south face of Lavarella to the lake "Le de Conturines" and short before Ücia de Gran Fanes head right (way 17) to the Vallon Bianco. On the crossing you can refill water in a little stream. After reaching the summit of Vallon Bianco same way back to Ücia Gran Fanes and all the way down on the roadway back to Ücia Pederü.
