Grand Boucan is La Réunion’s major carnival gathering in Saint-Gilles-les-Bains. The 2026 edition is confirmed for 28 June by the Ouest La Réunion tourism agenda, and the event keeps the island’s taste for street performance, satire, masks, music and collective procession visible in public space. Its importance comes from the way the carnival turns the seaside streets into a shared stage: residents, families, artists and visitors meet around costumes, floats and a deliberately exuberant local atmosphere. For a regional culture database, Grand Boucan works because it is festive, popular and rooted in the island’s contemporary public life rather than a simple imported show.
