The patron of San Giovanni al Natisone is Saint John the Baptist, celebrated on 24 June in the Church of San Giovanni Battista.
In the last week of June, in the square next to the church, the feast of Saint Peter is held, organized by a close-knit group of friends called «Chei di Dolegnan». In the hamlet of Bolzano stands the house where the Friulian poet Pietro Zorutti lived. The town also holds the Church of San Giusto and the public park of Villa de' Brandis.
