Ride that connects the Fassa Valley of Trentino with the valley Agordina in the Veneto and has the Marmolada mountains on the north and the Pala di S. Martino to the south.
The two primary routes from Moena and Falcade are both great rides up to the Passo Pellegrino. Coming from Falcade is the more challenging ride with ramps up to 15% and there is a tunnel you should ride around, using a service road. The route coming up from Moena is not as stiff of a ride but there tends to be traffic on the weekends.
