The patron of San Nicola dell'Alto is San Michele Arcangelo, celebrated on the first Sunday and Monday of May; the village holds the Santuario San Michele Arcangelo.
After nine days of prayer, on Sunday morning the saint, carried on shoulders, is brought down into the village; after a first tour of the streets he is placed in the Chiesa Madre (Mother Church). Particularly evocative is the procession that leaves the parish church at dusk on Monday and, winding through the old village, reaches the saint's little church on the mountain of the same name. The devotion of the people of San Nicola dell'Alto to their patron saint is particularly strong. The municipality also holds the Museo della civiltà contadina.
