Nahuel Huapi National Park, established in 1934, encompasses over 700,000 hectares of lakes, rivers, and mountains in the heart of the Argentine Lake District. The park is centered around Lago Nahuel Huapi, one of South America's largest lakes, and includes the headwaters of the famous Río Limay. The park's diverse water systems harbor exceptional populations of brown trout, rainbow trout, brook trout, and landlocked salmon. Strict conservation measures within the park maintain water quality and fish populations, making it one of the most reliable fishing destinations in Patagonia.
