I don’t think this festival needs much of an introduction as it is arguably one of this world’s most famous cultural festivals.  Though they are held in Portugal, Mexico, Southern France, and other parts of Spain, one of the most famous Running of the Bulls in the world happens in Pamplona, Spain during the eight-day Festival of Sanfermines in honor of Saint Fermin. During the festival, a part of the city of Pamplona is blocked off and a small group of bulls is let loose inside. The bulls run through the streets and it is customary for patrons, all wearing white, to run out ahead of the bulls and try to avoid being run over.
