Circular hike Aual Claif

In the dry Val Müstair, the meadows and fields have been artificially irrigated for centuries to secure and increase the yield. The water was often channelled over long distances from side streams or even from the main river Rom to the agricultural areas.

As part of the overall agricultural melioration, a network with modern irrigation systems was installed in the Val Müstair and the Auals visibly lost their importance. With the abandonment of the Auals, the old crafts and knowledge were also forgotten. Today, the value and functions of the Auals are mainly of a cultural-historical nature. But biodiversity also benefits from the still water-bearing Auals. Thanks to an initiative of the Swiss Landscape Conservation Foundation, the municipality of Val Müstair and the nature park, selected Auals have been restored for several years and the remains of former Auals have been made visible again in the terrain.
