Nahuel Huapi National Park is in the provinces of Neuquen and Rio Negro, in Patagonia, in the foothills of the Andes mountains. The Nahuel Huapi National Park is the oldest of Argentina's parks and was founded in 1934.

Nahuel Huapi National Park is in San Carlos de Bariloche, which is a city in Rio Negro, Argentina. Bariloche is one of those places you'll end up staying longer than you planned. It's not for the city's aesthetic appeal, rather it's for the great outdoors and night life. It's the elite honeymoon capital in Argentina. It's the main hub for travelling around the Lake District, the gateway to Patagonia and chocolate capital of Argentina.
