San Carlos de Bariloche, usually known as Bariloche, is a city in the province of Río Negro, Argentina, situated in the foothills of the Andes on the southern shores of Nahuel Huapi Lake. It is located within the Nahuel Huapi National Park. After development of extensive public works and Alpine-styled architecture, the city emerged in the 1930s and 1940s as a major tourism centre with ski, trekking and mountaineering facilities. In addition, it has numerous restaurants, cafés, and chocolate shops. The city has a permanent population of 108,205 according to the 2010 census. The name Bariloche comes from the Mapudungun word Vuriloche meaning "people from behind the mountain" (vuri = behind, che = people). The Poya people used the Vuriloche pass to cross the Andes, keeping it secret from the Spanish priests for a long time.
