Worth driving - check before if the pass is open when you visit. Unpleasant big stone once was put as a barrier to keep motorcyclist away. But if we had arrived to this point from another direction,we would not have had possibility to return, because this barrier was on a bridge. But nice scene - also when the pass is closed...
The SS345 takes you through the Parco Regionale del Adamello. Lots of high speed sweepers with fairly good tarmac.
