Brünig Pass

The Brünig Pass, at an altitude of 1,008 m , connects the Bernese Oberland and central Switzerland, linking Meiringen in the canton of Bern and Lungern in the canton of Obwalden. It is on the watershed between the upper reaches of the Aare, which flows through Lake Brienz and Lake Thun, and the Sarner Aa, which flows into Lake Lucerne.
The pass is crossed by the Zentralbahn's Brünig railway line, between Lucerne and Interlaken, and that line's Brünig-Hasliberg station is situated in the pass. The pass is also crossed by the A8 motorway, between Lucerne and Spiez. Both rail and road crossings are normally kept open throughout the winter.
