Lago Puelo National Park, nestled in the Chubut province of Argentina, continues its legacy of preserving Patagonia's unique biodiversity in 2025. Established in 1971 as an independent reserve after initially being part of Los Alerces National Park, it spans 27,674 hectares.
The park protects the Valdivian flora, a key feature of its ecosystem. This includes species like avellano, tique, lingue, and ulmo. Other notable trees are the ciprés de la cordillera, coihue, lenga, radal and arrayán. The park also has fauna like the pudú, huemul, red fox and cougar.
Visitors in 2025 can explore the park's trails, enjoy water activities on the turquoise waters of Lago Puelo, and appreciate the stunning landscapes shaped by glacial activity. The park's low altitude contributes to a milder climate compared to other Patagonian regions.
