"Désalpe" is the best-known of all traditional mountain festivities. After more than four months of grazing in alpine pastures, cows make their way down to the plain.

You'll see the "armaillis" dressed in "bredzons" and their ladies in "dzaquillons". As for the cows, thundering bells will be hanging from their necks and brightly couloured flowers on their heads. Parade, traditional music and selling of local produce among other things.
