Check out this beautiful drone video of a mountain pass in central Switzerland, compliments of krisna diantha. The Klausen Pass connects a town in the Uri Canton with another in the Canton of Glarus. The road which crosses the pass is just over 45 km (around 29 mi.) in length. The elevation of the pass is just under 2k meters (around 6.4k ft.), and it's usually closed between October and May. The road is part of the Alpine Pass Route which a hiking trail which runs through much of the Swiss Alps.
