San Carlos de Bariloche is a city in the province of Río Negro, Argentina, situated on the foothills of the Andes, surrounded by lakes (Nahuel Huapi, Gutiérrez Lake, Moreno Lake and Mascardi Lake) and mountains (Tronador, Cerro Catedral, Cerro López). It is famous for skiing but also great for sight-seeing, water sports, trekking and climbing. Cerro Catedral is one of the most important ski centers in South America.

The name Bariloche comes from the Mapuche word Vuriloche meaning "people from behind the mountain" (furi = behind, che = people). The Vuriloche pass was used by the Mapuches to cross the Andes and was kept secret from the European priests for a long time.

The city lies close to Chilean border and it is connected to Chile by the Cardenal Antonio Samoré Pass that crosses the Andes Mountains.

Tourism, both national and international, is the main economic activity of Bariloche, all year around. The main ski station is the one at Cerro Catedral. During the summer, beautiful beaches such as Playa Bonita and Villa Tacul welcome sun-bathers and some brave lake swimmers (the waters, from melting snow, are always very cold. Lake Nahuel Huapi averages 14 °C in the summertime). The fishing season is another great attraction. Bariloche is the biggest city of a huge Lakes District, and serves as a base for many excursions in the region. Trekking in the mountains, almost completely wild and uninhabited with the exception of a few high-mountain huts, is also a popular activity.

The city is also famous for its chocolates.There are about 100 private fabric of chocolate in the city.
