The Gersau ChlausNächte are a combination of Chlaus hunting, Trychler culture, Iffelen splendor, local Advent market and festive hut conviviality.

The highlight of the ChlausNächte is the Chlaus parade on Saturday evening with around ten different formations, which transforms the village into a feast for the senses during the dark period. Let yourself be enchanted by the rhythmic sound of the Trycheln and the dancing lights of the Iffelen. Other highlights include the Trychler and Iffelen procession on Friday, the arrival of Santa Claus on the Nauen (barge), the romantic market in the grove, the various snack bars in the park, the music in the festival hut, the brunch and Chlausä-Stubetä on Sunday and the activities for children.
