The Jungfrau (4158 m) is the highest mountain in the famous Jungfrau Region which is part of the Berner Alps. Other peaks nearby are the Eiger (3970 m) and the Mönch (4107 m). The region is the most glaciated part of the Alps and it contains Europe's largest glacier, the Grosse Aletschgletscher. In 2001 it became an UNESCO World Heritage site. Since both of us had never been in the region and because it is pretty much on the way from Munich to the Mont Blanc it became a natural choice for an acclimatization climb before attempting Mont Blanc (4810 m).
