With the arrival of summer, the villages of the Vall de Boí start to celebrate each year the Fallas, a sun and fire celebration, that has been designated World Intangible Cultural Heritage by the UNESCO.

The Fallas day, the “fallaires” go up to the “Faro”, a bonfire located in a high area and far from the village. When the night falls, the fallaires will light their "Falla" (a torch made previously with pine, ash and hazel wood) at the Faro to begin the descent towards the village. There they will be welcomed by the rest of the people with a party with music and another bonfire where they will burn the fallas.

During the summer there are other festivals and cultural events in the valley.
