Beautiful Tour.
Go through the Boite Valley till the village of Cibiana di Cadore (must stop to see the murals). Up to Passo Cibiana, the descent to Zoldo and Agordo is long but easy.
From Agordo go ahead to the Agordina Valley until you reach the villages of Alleghe and Caprile. Continue on the road along the villages of Sac and Larzonei to come out on the road that goes up to Passo Falzarego.
The descent to Cortina is known and very very panoramic.
