On 31 January and 1 February 2026, Onex will be buzzing with Guggenmusik brass bands and costumes for a popular, intergenerational celebration open to all.

For two days, Onex is transformed into a veritable carnival town, carried along by the energy of more than 300 musicians from Guggenmusik brass bands from Switzerland, France and Germany. Concerts, entertainment for all ages, creative workshops for young and old, costume competitions, shows, musical parades and a big festive evening punctuate the event. The highlight of this carnival immersion is a grand parade through the town, combining floats, brass bands and costumed groups in a whirlwind of colour, sound and conviviality. A popular and warm-hearted experience, where music, creativity and sharing invite everyone to fully embrace the spirit of carnival.
