Klausen Pass is a high mountain pass in the Swiss Alps connecting Altdorf in the canton of Uri with Linthal in the canton of Glarus. Somewhat unusually, the boundary between the two cantons does not lie at the summit of the pass, but some down the slope towards Linthal, with the summit being in Uri.The Klausen Pass is crossed by a paved road, which has a length, between Altdorf and Linthal, of. The road approaches the summit from Altdorf via the Schächen Valley communities of Bürglen, Spiringen and Unterschächen, and descends to Linthal via the Urnerboden. The road is normally closed between October and May, due to the high snowfall on the pass. During the open period, a PostBus Switzerland service crosses the pass several times a day, connecting Fluelen station, on the Gothard railway and Lake Lucerne, with Linthal station, the terminus of the railway line through Glarus.At the top of the pass is a historic chapel, the Bruder-Klaus-Kapelle, whilst to the west side of, and below, the summit is the Hotel Passhohe.
