From Altdorf towards Glarus Nord
I recommend starting in Altdorf UR and finishing towards Glarus Nord. The complete drive covers around 72 km and takes approximately an hour and a half without stops.
Of the three passes on RevToSummit, Klausen asks for the calmest approach. The road is narrow and winding, so even when traffic is only moderate you need to stay attentive and leave a proper margin.
