The patron of Niardo is Sant'Obizio, celebrated on the first Sunday of May.
The municipality also holds the Chiesa di San Maurizio, the Chiesa di San Giorgio, the Monte del Palo and the Monte Zincone. During the solemn celebrations the Corazzieri di Sant'Obizio (Cuirassiers of Sant'Obizio) escort the urn of the relics through the streets of the village; the feast also honours San Costanzo and Blessed Innocenzo da Berzo. In October the Mercàt dei Pom e de le Patate (apple and potato market) is held in the courtyard of the birthplace of Blessed Innocenzo, in via Sommavilla; at the end of August, in the locality of Crist, the Sagra del Cinghiale (wild boar festival) takes place.
