Every year around Pentecost (late May or early June), Nosy Be holds a week-long music festival known as the Donia. Groups from Madagascar, neighbouring islands such as the Comoros, Réunion and Mauritius, and France perform a wonderful mix of rock, reggae, Creole and pop. Fringe events include a carnival, sporting events and seminars. Around 50,000 people attend every year, and the island is at its most effervescent. The main venue is Hell-Ville, although there are events across the island.
