Bariloche (known formally as San Carlos de Bariloche) is a medium sized town (pop. 130,000) in the Rio Negro Province of Patagonia, Argentina. It's famous worldwide for its massive ski resort, Cerro Catedral, which has more than 1200 hectares of skiable / ridable terrain, and the most modern snow sports infrastructure in South America.
Bariloche has a spectacular setting, with most of the city built on the Andean foothills rising up from a series of enormous alpine lakes, most notably Nahuel Huapi. In addition to Cerro Catedral, several other large mountains form an imposing ridgeline above the city, including Cerro Tronador (The "Thunderer"), which is a classic peak for mountaineering.
Easy access via an international airport, combined with the city's immediate proximity to backcountry terrain (including Nahuel Huapi National Park) has made Bariloche a popular hub for outdoor adventurers and travelers of all kinds in recent years. It can get very crowded here during the high season (mid-December until the end of February) and again during ski season in late June-August.
