Sanfermines: A Week of Controlled Chaos in Pamplona
For nine days each July, the medieval streets of Pamplona surrender to a tradition that transforms the city into something between a religious pilgrimage and a street carnival. The Festival of San Fermín begins at noon on July 6 with a firework called the chupinazo launched from the city hall balcony, and it does not quiet until midnight on July 14, when thousands gather in the City Hall Plaza to sing the melancholy song "Pobre de mí"—Poor Me—as they extinguish their candles and remove their red handkerchiefs. What happens between those moments is why people plan their summers around these dates.
The Run That Defines the Festival
Every morning from July 7 to 14, the encierro—the running of the bulls—begins at 8 am. Hundreds of runners move through 825 metres of Pamplona's narrow streets, staying ahead of six fighting bulls and six steers that guide them toward the bullring. Before the run starts, runners gather at a small statue of San Fermín in a wall niche and sing a chant three times, asking for the saint's protection and blessing. A firecracker signals the release of the bulls; a second firecracker signals the last bull has left the corral. What you experience is not a tourist spectacle but a genuine test of nerve—each day features a different encaste, or sub-breed, of bull, meaning the dynamics shift across the week. Since 1925, the event has claimed 15 lives, and between 200 and 300 people sustain injuries annually, most often from falls rather than direct contact.
Street Pageantry and Sacred Procession
Between the morning runs and the afternoon bullfights lies a festival woven from both piety and spectacle. Each morning, a parade of gigantes y cabezudos—giants and big-heads—processes through the streets. The eight giant figures, built in 1860 by painter Tadeo Amorena, stand more than 150 years old and represent four pairs of kings and queens from Europe, Asia, America, and Africa. They are carried inside wooden structures by dancers who animate them through the crowds.
The spiritual heart falls on July 7, when a 15th-century statue of Saint Fermín is carried through Pamplona's old quarter in a procession led by the Bishop of Pamplona and accompanied by dancers and street entertainers. As the gigantes dance, the cathedral bell María peals, and the Jota—an ancient traditional dance—is performed in the saint's honour. A rose is offered at the Saint Fermín well, and High Mass is held in the cathedral and parish churches.
Nights of Unbounded Energy
The festival's official schedule frames the days, but the streets belong to the crowds at night. At some point during the week—on a different day each year to manage crowds—an event called el Struendo occurs. "The Roar" is not officially scheduled; at 23:59, people gather at City Hall and make noise for hours with drums, cymbals, bowls, whistles, and pans. It is deliberate chaos sanctioned by tradition, a release valve for the intensity that builds across the nine days.
When to Arrive
The festival runs from noon on July 6 through midnight on July 14 each year. If you come for the opening, you will witness the chupinazo and feel the initial surge of energy as the city transforms. The closing ceremony on July 14 is its own kind of powerful—a collective moment of reflection as thousands sing "Pobre de mí" together in the plaza before the final fireworks. The runs themselves demand early mornings and nerve, but they are the core around which everything else rotates.
Sanfermines is not a festival you watch from the sidelines. Whether you run, process, parade, or simply move through the streets as the city changes around you, you are participating in something that has evolved from medieval fairs and cattle markets into a week when Pamplona operates by different rules. The question is not whether to go, but whether you can arrange your life to be there when it happens.
