San Carlos de Bariloche sits on the southern shore of vast Lake Nahuel Huapi, where the Argentine steppe gives way to the snow-capped peaks of the northern Patagonian Andes. Often called the heart of Argentina's Lake District, it is the country's most loved mountain town, an alpine-flavoured base for hiking, skiing, kayaking, and slow scenic drives, all wrapped around a walkable downtown of chocolate shops, craft-beer bars, and lakefront views.
The town earned its Swiss-Bavarian look from the European immigrants who settled the region in the early twentieth century. That heritage still shows up in the stone-and-timber Centro Civico, in the alpine chalets along the lakeshore, and in the two things Bariloche is most famous for: artisan chocolate and craft beer. Avenida Mitre downtown is lined with legendary chocolaterias like Rapa Nui and Mamuschka, while breweries such as Berlina pour Patagonian ales brewed with glacial meltwater.
Most of the scenery lies just west of town along Avenida Bustillo, the lakeshore road that strings together Bariloche's headline sights. The classic outing is the Circuito Chico, a 60km loop past beaches, viewpoints, and the storybook Llao Llao peninsula. Along the way, a short chairlift carries you up Cerro Campanario, a summit that National Geographic ranked among the best views in the world: a 360-degree panorama of layered lakes and Andean peaks. Further out, Cerro Catedral is South America's largest ski resort in winter and a gateway to superb day hikes, like the trail to Refugio Frey, in summer.
