Every year on 23 June, the night before St. John's day ("nit de Sant Joan"), there is a ceremony called "Flama del Canigó" (Canigou Flame), where a fire is lit at the mountaintop. People spend the night there and take torches lit on that fire in a spectacular torch relay to light bonfires somewhere else. Some estimates conclude that about 30,000 bonfires are lit in this way all over Catalonia on that night.
