The patronal feast of Lavis is celebrated on 8 September for the Nativity of the Blessed Virgin Mary, a feast that retains strong popular devotion and is linked to a vow made by the community in 1702.
In spring the Fiera della Lazzera is held, an old fair marked by numerous stalls and commercial activities tied to the arrival of the warm season. The town also holds the Church of Sant'Udalrico and the Church of the Madonna di Loreto.
