In addition to the beautiful landscape, you should also take a look at the flora. Just as interesting are the numerous glacier traces along the path, such as rounded humps and glacier scratches.

The glacier gate of the Unteraargletscher in July 2023. Although the lower part of the glacier tongue is covered with gravel, the glacier is still losing its length every year.

There used to be ice here, now a glacier stream meanders and plants sprout up. The Unteraargletscher is the fourth largest glacier in Switzerland. However, it has also lost over 200 meters in height since 1850 and over two and a half kilometers in length since 1870.
