One of the most important things of these holidays are the infamous "Peñas" -"groups of people from Villamañán or somehow related to it, who usually are friends, that get together and create "clubs" in different places of the town, under certain requirements, to celebrate these holidays"-. "Peñas" are definitely the life of the party and the most important aspect of the celebration of these holidays. It is a very big tradition for people who celebrate the "Blackberry Holiday" or "Fiestas de la Zarza" to "ir de peñas" ("go from "peña" to "peña""), for the most part late at night until well past the down and enjoy everything they have to offer, mostly, but not limited to, alcoholic drinks and music.
