The patron of Robbio is Our Lady of the Rosary, celebrated on the first Sunday of September.
Starting on the last Sunday of August, the week-long Palio dl'Urmon is held, whose history begins with the felling of a great elm tree, called «urm» in dialect: every evening, the town's eight districts compete against each other. During the Palio, local beef can be enjoyed, including cotechino sausage. The town also holds the Castello di Robbio and the Church of Santo Stefano Protomartire.
