San Fermín / Running of the Bulls (Pamplona, Spain)

San Fermín delivers an electrifying eight-day street festival that draws over 1.5 million visitors annually, blending ancient traditions with high-octane risk. The daily running of the bulls, where participants race ahead of six bulls through 875-meter barricaded streets, tops the adrenaline scale. In contrast, the Feria de Abril focuses on relaxed socializing in casetas. San Fermín's rocket-launch at noon kicks off each day, followed by giant parades and all-night revelry, while the melancholy “Pobre de Mí” ceremony closes the spectacle. Despite the controversy, it outperforms #6 Songkran in international media coverage, with CNN reporting 300+ press credentials issued yearly. The festival's economic impact hits €150 million, surpassing the average street fair by 200%.
