Every year at the end of August in the picturesque setting of the Natural Park of the Caves of Oliero, Valstagna hosts the Brintaal Celtic Folk Festival, one of Italy's most important Celtic festivals which boasts of the participation of a large number of visitors. The Festival, founded in 2002, is an event, which has obvious roots in tradition and in the local area, but which also breathes through the sprouts projected on all Celtic lands and on the future, with the aim of fostering the awareness of culture, music, traditions, gastronomy of the Celtic world and its affinity with the people of Veneto.
