The magnificent Bernese Oberland is part of the Swiss Alps, and it’s between Lake Geneva and the river Reuss, the Bernese Oberland rises above the 4,000 m/13,124ft mark in the Finsteraarhorn (4,274 m/14,023ft), the Aletschhorn (4,195 m/13,764ft), the Schreckhorn (4,078 m/13,380ft), the Mönch (4,099 m/13,449ft) and the Jungfrau (4,158 m/13,642ft).
The massif is drained on the north by the Saane, Simme, Kander and other rivers, on the south by the Rhône, which is fed by the Aletsch glacier and Rhône glacier and by its right-bank tributaries. The Rhône forms the southern boundary of the Bernese Oberland until it flows into Lake Geneva.
