The patroness of Isolabona is Saint Mary Magdalene, celebrated on 22 July, with the church dedicated to her at the heart of the town. In the month of July, at the Doria Castle, the International Harp Festival is held, while at the end of July the traditional pallapugno tournament takes place, called «balùn» in local dialect.
Isolabona also preserves the sanctuary of Nostra Signora delle Grazie and the church of San Giovanni Battista.
