Some info from the net:
The Canigou, el. 2,784.66 m. Is a mountain located in the Pyrenees of southern France.
Due to its sharp flanks and its dramatic location close to the coast, until the 18th century the Canigou was believed to be the highest mountain in the Pyrenees.
Spectacular jeep tracks on the north side of the massif lead to the Chalet de Cortalets (at 2150 m.) which is a popular outpost for walkers.
There are two ancient monasteries at the foot of the mountain, Martin-du-Canigou and Saint-Michel-de-Cuxa.
This mountain has symbolical significance for Catalan people. On its summit there is a cross that is often decorated with the Catalan flag. 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 keep a vigil during the night 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.
