National Park Lago Puelo
The origin of the name of the Park, which is due to Lago Puelo, derives from the Mapuche voices puel, which means east, and co, which means water.
In 1937, the Argentine State, under Decree Nº 105.433, declared several Andean-Patagonian zones as reserves destined for national parks. Among them was Los Alerces in the Province of Chubut, which had an annex located about 115 km north. Later, in 1945, under Decree-Law Nº 9504 ratified by Law Nº 13.895, it was declared Los Alerces National Park keeping the Annex. In 1971, the Law 13.895 was modified by Law Nº 19.292, which grants the status of National Park to, until then Puelo Annex.
