This Patagonian park is the oldest designated national park in Argentina, having been established as a place of extreme national beauty and heritage in 1934. It spans the Neuquen and Rio Negro provinces, and many visitors will pass through the Nahuel Huapi National Park when they are in Bariloche, as the city is surrounded by the park. It is also home to the Lake District, owing to the many picturesque lakes that are located within the park.
