Carnival Parades & Flower Parade Nice Carnival, the premier international Carnival in France, is the most important winter event on the Côte d’Azur. Two weeks of festivities bring the city of Nice to life – the “Carnival Parades” (“Corsi”) day and night, and the elegant “Flower Parades” are on the schedule for this unmissable event. Lots of floats decorated and presented under the season’s theme parade to the rhythm of street art troupes and musical groups from all kinds of backgrounds (from all over the world), all in a colourful, festive, family atmosphere.
