The Euskal Jaia (Basque Festivity) is held on 9th September, the festivity of the Virgin of Aranzazu. This is an inescapable one week event (from 1st to 9th) celebrating local culture and traditions. Created in 1924, in order to encourage tourists to stay longer in the town, it has become a very popular event as it combines many Basque festivity traditions.
On these days, the streets are filled with groups of dantzaris (Basque dancers), accompanied by “txistus” and other regional instruments.
