In the Lago Puelo National Park, this beautiful greenish blue water mirror lends its name to the protected area. The lake empties into the river bearing the same name, which runs from North to South and joins Lake Interior in Chile through its western arm. In addition to these features, its valley has a particular micro climate, with better conditions than the mountain range environments.
This protected area which includes the valley of Lake Puelo and which used to be attached to the Los Alerces National Park, was created in 1971. Situated in the northwestern end of the Province of Chubut, on the border with Chile, it preserves the basin of the river bearing the same name and the smallest park in the Patagonian region, which shelters the forests, the steppe and the area of the high Andes.
The sceneries surrounding Lake Puelo may be beheld from a quiet lake ride on board the Juana de Arco. This old craft was brought to the cold waters of the Nahuel Huapi from the district of Tigre in Buenos Aires in the 1960's.
