Hellfest, also called Hellfest Summer Open Air, is a French rock festival focusing on heavy metal music, held annually in June in Clisson in Loire-Atlantique. Its high attendance makes it the French music festival with the largest turnover. It is also one of the biggest metal festivals in Europe and the first to exist in France.
Its programming is primarily focused on hard rock and metal on the two main stages, while each of the four other festival’s stages are dedicated to a particular style like black metal, death metal, doom metal or stoner metal
