The main participants in the processions are the "cuadrillas": teams or squads of people, usually based around members of the same family or their relatives by marriage, who parade through the streets in costume on several of the carnival days. Although activities and partying take place all around the town, the focal points are the plazas outside the town's two main churches, San Sebastián (the red brick church of the upper town) and La Señora de la Candelaria (the cream and yellow painted church of the lower town), set just one block apart from each other. All the processions end at one or other of the plazas, and temporary stages set up in each plaza are used for the presentations made by the "cuadrillas", and also for the live music and folkloric dance presentations that occur during the day and evenings of each day of the festival. The music is usually provided by salsa bands or "chirimías" - bands named after the woodwind instrument similar to a primitive oboe that they play, as well as guitars and drums.
