The fauna can be divided between high Alpine fauna and low Alpine fauna. At heights above in the Val Lumnezia the marmot and the chamois are of common occurrence and the Alpine ibex can be seen occasionally. Below that altitude, foxes, hares, wild boars and red deer can be found. With the onset of winter, the chamois move towards the valley. As there is a brown bear sanctuary some Alpine valleys further to the east, in Trentino of Italy, it might occasionally happen that a bear from this sanctuary ventures through lower ranges of the Val Lumnezia. Some caves and buildings of the lower Val Lumnezia are inhabited by the horseshoe bat (Rhinolophidae), which is a protected species.
