San Fermín is nine electrifying days in July where the streets of Pamplona erupt in red-and-white revelry, culminating each morning in the legendary encierro where thousands of runners dash alongside fighting bulls through the ancient cobblestoned old town. Whether you run, watch from the barriers, or simply soak in the relentless fiesta energy, this is one of the most raw and thrilling cultural experiences on the planet.
The encierro (run) starts at 8 AM sharp each morning July 7–14 — runners must be in position by 7:30. Wear white with a red neckerchief. The route is 875 meters and lasts under 4 minutes; the most dangerous sections are the curves at Estafeta. Book accommodation in Pamplona a full year ahead or base yourself in San Sebastián and take a bus in. The festival is nine days of non-stop street parties beyond just the run.
