Jungfraujoch is a notable saddle in the Bernese Alps, connecting the two four-thousander peaks Jungfrau and Mönch, at an elevation of 3,466 metres above sea level. It is a glacier saddle, on the upper snows of the Aletsch Glacier, and part of the Jungfrau-Aletsch area, situated on the boundary between the cantons of Bern and Valais, halfway between Interlaken and Fiesch.
