The Office of Mountain Guide has a long tradition in the Picos de Europa that begins with one of the most important events in Spanish mountaineering: the first ascent of Naranjo de Bulnes on August 5, 1904, as he was a local from Caín, Gregorio Pérez Demaría, who led Pedro Pidal, Marquis of Villaviciosa, to the top of the mythical "Picu".Today, the Guides live and develop our trade in these mountains, willing both to lead groups on well-known paths and to ensure a climb to any of the beautiful peaks of the Picos de Europa National Park.
