The Carnival of La Bañeza (also called winter festivals, carnivals, the run of carnival, antruejo), in the province of Leon, is a festival declared of national tourist interest that began to gain importance and fame at the beginning of the 20th century during the repression under Franco, due to the prohibition of concealing one's face or wearing a costume.  
The main characteristic of La Bañeza's carnival is the absence of a costume competition with prizes and monetary compensation for participating, which may occur in carnivals elsewhere. Most of the city dedicates themselves wholeheartedly to the festival, passing on interest through generations. In many cases, participants prepare a year in advance, searching for accessories, fabrics, masks and acts they will perform, motivated by a "carnival feeling", lived during those days. Given this, the disorganized carnival is becoming increasingly popular, dressing up outside of parade hours, or on days without events, in the workplace, etc. looking to surprise and amaze the citizens and visitors.
 The preparation of the celebration begins with the choice of the poster to represent carnival, through a competition organized by the city of La Bañeza. In the month of November, meetings are held with the groups participating in the parades to reach an agreement on the time, number of groups, and music or travel aspects.
 Although not an officially organized event, it is of vital importance throughout the year; group meetings, gatherings of friends and family, where the participants discuss ideas and design costumes, looking for originality, often staying in strict secrecy to cause the largest possible impression. As winter comes, many participants begin to make their carnival costumes, although another percentage improvise and make their costumes with less time to spare, often coming out equally graceful.
 Since 2006, the group Los Tranquilos have organized a monologue contest, in which participants have to dress up. From Christmas until the arrival of the carnival, the contest takes place once a week in different collaborating establishments, with the final on Piranha Saturday. Over time, the number of visitors and the level of the participants has been increasing, becoming a meeting place for different carnival participants. Totally unexpectedly, in 2008, a carnival karaoke contest also sprung up at a theater cafe in the city. In this contest, the participating groups prepare a song with choreography and costumes, delighting the audience.
 Carnival in La Bañeza usually begins on Thursday, the day the Salsa group declares the muse of carnival, a figure represented by a young girl of the city, chosen by the members of the group. In this act, in addition to the declaration, there is a preacher figure, theater shows, musicians and comedians. The Salsa group is one of the oldest groups participating in the parades.
 The group Los +Turba2 begin the procession of San Turbadín at mid afternoon on Friday; with the naming of the "hermano +turbado", a title given to an outstanding carnival participant; upon continuation, they leave the main square following a particular route through various bars of the city, the followers continue the procession, dressed in religious costumes, to the sound of a charanga band.  Notably backing up the procession is the processional float of San Turbadín, carried by the "hermanos turbados".  
"Tranquilo Friday" gets its name from the celebration organized by the group Los Tranquilos where at the end of their annual dinner, they honor one or various carnival participants.  After, there is a party attended by a multitude of costumed people.  There, they declare their decision for the best group of the previous carnival, the most original group and a special appointment.
 Saturday, La Bañeza converts into a great improvisational theater filled with people in costumes that do not stop interacting with the visitors. Traditionally, Saturday de Chispas, was called this due to the character El Chisposo, a cat who from the balcony of the townhall, would sing the popular song "Estaba el Señor don Gato". The attendees would dress wearing original hats that they made themselves, decorated in allegorical representations or original touches of color; while the main square was lit up by the flares carried by the dressed up people.  Today, this representation has given way to a crowd of people dressed in costumes from all parts of Spain.  Even so,  the name Saturday of Chispas still remains.
 The day begins in a totally surprising and spontaneous way. In the early morning hours, coinciding with the market of La Bañeza, many carnival participants perform small comic and theatrical acts evoking great interest among the visitors.  This day is of increasing importance and is one of the greatest impulses by the young as it goes back to the roots of an institutionally disorganized carnival. Late in the afternoon, the proclamation giving the official start to carnival takes place (normally accompanied by musical acts, theatrical groups and comedians of the city). Then, many people dressed in costumes, attend the dinner of the exaltation of carnival, organized by the city council. Upon finishing dinner, the celebration begins with the sound of the brass bands of La Bañeza, allowing for the enjoyment of a night filled with jokes, pranks and humor by the disguised participants, in the center of the city.
 Sunday morning, the Carnival Race is organized, being an allegory to the term the run of carnival. It consists of a gymkhana that goes from the old train station and to the main square. All the participants are dressed up, going in front of people dressed as security forces who try to make sure no one reaches the end of the course. Although primarily for younger children, there are people of all ages. At 5:00 pm, the parade of the previous year starts, where groups and individuals wear the same costume they wore the previous year, accompanied by floats and brass bands. Also making an appearance in the parade is the queen of carnival, accompanied by her maids of honor and the muse of carnival.
 In any business in La Bañeza, one can find the owners and employees dressed up for carnival. On Monday, like Saturday morning, crowds of people dressed in costumes re-emerge, cheering through the streets of the city. Another important feature is to see the people at work, dressed up to the surprise of visitors. At 5:00 pm, the children's parade begins, where children are the stars in a colorful parade with a shorter route.
 At night, starting at 12:00 am, Nochebruja begins. Created in 1985 by thousands of carnival enthusiasts coming from numerous geographical points of Spain. It's the busiest night of people in costumes that can go until the early hours of the morning, in the streets and bars of the city, making it a major festival in northern Spain.
 The Tuesday parade of carnival through the streets of La Bañeza.
The Tuesday of Carnival, at 5:00 pm, the big parade starts off, led by the muse of carnival along with the Salsa group and ending with the queen of the festival and her maids of honor. This is the most important day of the celebration, as all attendees dress in the costumes they designed and made throughout the year in secret. At the end, all the participants are given a bun filled with chorizo. The number of visitors is very important, but has led to circulation problems in traffic on the access roads to La Bañeza. The number of groups exceeds fifty. This day, along with August 16 are chosen as local holidays in the city.
 La peña La Sardina organizes the Burial of the Sardine, a funeral procession made up of the group members, characterized by a suit, coat, hat and long beard, the carriers of the coffin, a white tunic, hat and slippers and the mourners, representing the widows of Don Carnal. All of them are accompanied by a brass band that mixes the rhythms of carnival with those of the funeral. It starts in the Bar Industrial and goes to the main square where after a reading by the character of El Corvillo of ballads of satire and irony about what happened in the city during the year, bread, pickles and wine are freely distributed, and it ends with the burning of a figurine in the shape of a sardine.
 In the Mojao Neighborhood, the final events of the masquerade are organized, with special prices for the area for those who come in costumes.
