Carnival
Three main parades take place during Carnival. The first is held on the first day, during which the "Carnival King" (either a person in costume or an effigy) rides through the city on his carriage. The second is held on the first Sunday of the festival and the participants are mainly children. The third and largest takes place on the last day of Carnival and involves hundreds of people walking in costume along the town's longest avenue. The latter two parades are open to anyone who wishes to participate.
