The patron of Arsiè is the Assumption of Mary, celebrated on 15 August in the Church of Santa Maria Assunta.
The town's most attended event is the Fiera delle Anime, born when the new parishes of Enego, Primolano and Fastro broke away from the Pieve di Arsiè, and officially recognized by a papal bull of Pope Alexander VII on 15 October 1666. Coinciding with the end of the alpine grazing season, it soon became a time of barter and trade, and still today draws people from the whole surrounding area on the third Sunday of October. In recent years the Arsiè Summer Fest, a sports festival, has also been growing. The town holds the Covolo di Butistone and the Forte Leone.
