The patron of Casalvecchio Siculo is Saint Onuphrius, celebrated on 12 June in the church dedicated to him.
The hamlets keep their own dates: in Misitano the feast is on the last Sunday of July, with a few festivals of local produce. The village clings halfway up Monte Sant'Elia, in the Agrò valley, and its territory includes the church of Santi Pietro e Paolo d'Agrò.
