The pile is lit in October and during these days there is always a coal man day and night, ensuring that the burning is correct. The coal men, however, don't spend much time alone. During the day many people and school groups come along, and at night there is also a lot of people observing it. There are even people who decide to camp and spend the night next to the pile. It also must be said that there are some who use the excuse to have lunch and cook in a privileged natural environment.
What started initially as an activity of a marked pedagogical and anthropological nature, as well as leisure, has become one of the most unique festive and cultural events of the municipality. From this corner of the Gavarres the memory of a lost trade has been recovered, that of the coal trade.
The setting of this successful festival, which from the beginning attracted many visitors, kept changing until in 1996 it began to take place in Forallac, in the area known as the Sobellàs, of Sant Climent de Peralta, one of the last coal mining squares of the massif. From the beginning, those responsible for the coal organisation were the Association of Friends of Cau dels Pins, of Sant Climent and Santa Susanna de Peralta, who have been supported by the Town Hall.
Over these days, in addition, parallel activities are organised, linked to the dissemination of the natural heritage and human heritage of the Gavarres massif. Together, all these days make Sobellàs the epicentre of the leisure and cultural activity of the municipality, in one of the busiest places in the county.
