Passo 2 santi, known for its winter facilities, but it is also possible to stop in summer, there is a bar and restaurant and a way to stock up on water
From Pontremoli the road is all uphill, but the real slopes begin in Noce. From there it is about 9 km with a gradient of 9.5%, on a road with a less than perfect surface. It is wonderful to arrive in the locality of Zum Zeri: right on the top it is possible to stop at a refuge.
A beautiful mountain pass at 1,400 meters. There's a refuge, a small chapel, a monument—in short, everything you'd expect in a place like this. There's even a small clothing store. The only thing that's jarring is the constant noise of a combustion engine, which I assume is a generator for the refuge's operation.
