The carnival groups march the streets to the rhythm of frying pans, saucepans and traditional melodies, filling the city with sound and colour.

Dressed as old Hungarian boilermakers, they parade through the city centre and neighbourhoods, creating a festive atmosphere that captivates both Donostiarras and visitors alike. The music, the humour and the public participation make this an unmissable winter date.

The Caldereros are a tradition that marks the beginning of weeks of celebrations in the city.
