Aar Glaciers, Alpine glacier system in Bernese Alps, Switzerland
The Aar Glaciers are two connected ice systems, the Unteraargletscher and Oberaargletscher, located in the Bernese Alps and serving as the source of Switzerland's longest river. These frozen masses form a dramatic high-altitude landscape that can be explored on foot from the surrounding terrain.
The glaciers became subjects of intensive study starting in the 18th century and played a central role in establishing glaciology as a scientific discipline. Extensive observations here helped shape fundamental understanding of how ice masses move and transform over time.
The Aar Glaciers serve as an educational site where researchers and students examine glacier dynamics and environmental changes in the Swiss Alps.
The best time to visit is during warmer months when paths and mountain passes are more passable without heavy snow and ice. Access is via the Grimsel Pass road, which also leads to the hospice building offering lodging and food for those planning to stay overnight.
The Oberaargletscher displays particularly visible glacial streams and crevasses that hikers can observe up close on their approach. The gorge below this ice mass reveals how glaciers continue to shape the landscape through erosion and meltwater flows.
