The patron of Luco dei Marsi is Saint Boniface IV, celebrated annually in the second half of August.
Between February and March, on Shrove Tuesday, the Carnevale Marsicano is held. On Pentecost Sunday, between May and June, the rite of the «Panarda marsicana» is renewed: the feast of the Holy Spirit has been documented since 1479. The feasts of Our Lady of Grace, Saint John the Baptist and Saint Andrew the Apostle are also celebrated annually. The town also holds the Shrine of the Madonna di Candelecchia and the archaeological area of Lucus Angitiae.
