The patron saint of Cerrione is Saint John the Baptist, celebrated on 24 June.
The town's other two hamlets have their own patrons: Vergnasco celebrates Saint George, to whom the local Parish Church of San Giorgio Martire is dedicated, and Magnonevolo celebrates Our Lady of Mount Carmel. The municipal territory also holds the Bessa Nature Reserve and the Oratory of Santi Rocco e Grato, as well as the Parish Church of the Madonna Annunziata.
