Jungfraujoch

Executive summary by darmansjah

The Jungfraujoch is a col between the Jungfrau and the Mönch. It lies at a height of 3,466 meters above sea level in the Bernese Alps, on the boundary between the cantons of Bern and Valais, halfway between Interlaken and Fiesch. It is a glacier pass, on the upper snows of the Aletsch Glacier, and part of the Jungfrau-Aletsch area.

Since 1912, the Jungfraujoch is accessible to tourists by the Jungfrau line, a railway from Interlaken and Kleine Scheidegg, running partly underground through a tunnel through the Eiger and Mönch. The Jungfraujoch railway station, at an elevation of 3,454 meters is the highest in Europe. It lies east of the saddle, below the Sphinx summit, and is connected to the Top of Europe building, which includes several panoramic restaurants and a post office. Several tunnels lead outside, where secured hiking trails on the crevassed glacier can be followed, in particular to the Mönchsjoch Hut.

The Sphinx Observatory, one of the highest astronomical observatories in the world, provides an additional viewing platform at a height of 3,571 meters. It can be reached by an elevator from the Jungfraujoch. The observatory houses one of the Global Atmosphere Watch's atmospheric research stations. The Jungfraujoch radio relay station, which is not accessible to the public, is installed west of the Jungfraujoch, on the Jungfrau ridge. It is Europe's highest radio relay station.
