Río Negro
Explora Nuestras Provincias y sus Riquezas is part of Argentina al Mundo, alongside Argentine Delights, Guía AD-Gourmet and Chefs Argentinos al Mundo.
Río Negro, from the Andes to the sea. In Bariloche, Nahuel Huapi reflects snow-capped mountains and ancient forests, and from Cerro Catedral and Cerro Otto Patagonia unfolds at your feet. Further south, El Bolsón, among farms, hops and artisans. A river crosses it from end to end, irrigating the Alto Valle of apples and pears, until it reaches the sea at Las Grutas. Chocolates, craft beers and the talent of INVAP that reaches space. Río Negro is not toured: it is lived in every season. Río Negro is all of Patagonia in a single province.

Natural wealth
The territory that defines it
Río Negro crosses Patagonia from the Andes to the sea, and along the way it brings together very different landscapes and climates. The Andean region, of lakes, forests and snow-capped mountains, with Bariloche and El Bolsón. The Línea Sur, the great steppe plateau of herders and merino sheep. The Alto Valle and the Valle Medio, fruit-growing oases irrigated by the Limay, Neuquén and Negro rivers. And the Atlantic coast of the San Matías Gulf, with Las Grutas, mild beaches and marine wildlife that includes Islote Lobos National Park.

South of Bariloche, in a valley between snow-capped ranges, El Bolsón is a land of farms, berries, craft breweries and its famous regional artisans' fair. Cerro Piltriquitrón and the Azul River frame one of the most singular areas of Patagonia. Every February it celebrates the National Hops Festival.

Human wealth
The living figures
Río Negro is one of the country's top tourist provinces: Bariloche welcomes travelers from all over the world every year and is the great destination for graduation trips. Its identity combines the Mapuche and Tehuelche heritage, the culture of the valley's fruit farmers, children of Italian and Spanish immigration, and the Central European imprint of the mountains. At the table, chocolates, craft beers, smoked foods, berries, Patagonian lamb, trout, and pears and apples from the valley.

Bariloche is home to INVAP, the Río Negro state technology company that built research nuclear reactors for countries such as Australia, Egypt and Algeria, and satellites such as ARSAT and SAOCOM, and to the Balseiro Institute, created in 1955 alongside the Bariloche Atomic Center, the cradle of physicists and nuclear engineers.
