- December 4: Saint Barbara, Anniversary of Vacas.
Every year on December 4, combined with a couple of activities, the population of Vacas celebrates its anniversary of foundation and the feast of its patron Saint Barbara whose image is venerated with much devotion by the residents and people from abroad. The pilgrims come to worship and to ask their patron for little favours, especially for rain and the protection from lightning.
There is a traditional tale telling that many years ago Saint Barbara appeared as a shepherdess on the shore of Qucha Quchita. The people who arrived at this place attracked by the incident found a beautiful image of the saint which they carried to the village of Vacas. Because of this event Vacas was founded officially as Santa Bárbara de Bacas in the middle of the 17th century.
