Mandelieu-La Napoule on a idyllic stretch of the French Riviera is the capital of the mimosa, which blooms from January to March. The annual Mimosa Festival celebrates this bloom with parades, floats, street performances and more. The festivities begin in the chapel of Notre Dame des Mimosas with moonlight parades each night of the festival. The action takes place along the La Napoule harbor with overflowing flower floats dressed to impress.
