This company offers two excellent tours that explore two peculiarly Spanish obsessions: the toro (fighting bull) and the cerdo ibérico (Iberian pig, from which jamón is made). The tours take you to the village of Cabeza de Diego Gómez, west of Salamanca. You'll need your own wheels to get here (ask for directions at the tourist office in Salamanca).

You'll need at least passable Spanish to get the most out of either tour.
