Serpentine by serpentine the incredibly scenic drive that links the cantons of Uri and Glarus pulls up in front of a beautiful mountain panorama way up the pass summit. The road is asphalted. The Klausen Pass is the first "major" alpine pass you reach driving south from Zurich, in fact, using the highway you can be at the foot of the pass in a little over 1 hour - it really is a passage directly into the heart of the Alps. At the summit there are a gift shop, a snack bar and a public toilet. The road is closed from November to June-July due to the high snowfall on the pass.

The road to the top is called Klausenstrasse. It was opened in 1948. It’s a pleasant road with a great view and very good surface, well known spot for motor bikers, and cyclists. At the top of the pass is a historic chapel. The drive never gets too busy. This is a must drive if you can deal with a very narrow curvy mountain road. The pass is littered with tiny alpine villages.
