Jungfraujoch

The Jungfraujoch is a col or saddle between the Mönch and the Jungfrau in the Bernese Alps on the boundary between the cantons of Bern and Valais.

Strictly, the Jungfraujoch is the lowest point on the mountain ridge between Mönch and Jungfrau, at 3,471 metres in height. It is just above this location that the mountain station of Jungfraubahn is located, which at an elevation of 3,454 metres is the highest railway station in Europe. The Jungfraujoch is often called the "Top of Europe" in tourist literature.

Not far east of the Joch rises a peak called the Sphinx, which tops out at an elevation of 3,571 metres. It begins from the Jungfraujoch on the Valais side and at the Great Aletsch Glacier. There is an elevator to the summit of the Sphinx, where a small viewing platform and a scientific observatory are located.

The Jungfraujoch is also home to one of the Global Atmosphere Watch's atmospheric research stations. The Jungfraujoch can only be accessed through a 7.3 km long cog railway tunnel, served by the Jungfraubahn, the highest in a series of cooperating railway companies that provide access to the Jungfraujoch from Interlaken.
