Nahuel Huapi National Park is the oldest national park in Argentina, established in 1934. It surrounds Nahuel Huapi Lake in the foothills of the Patagonian Andes, and encompasses nearly 2 million acres.
The park's wild lands are absolutely stunning, with huge lakes, rivers, waterfalls and soaring mountains. Getting here is tough. It's in south Argentina and bordered by Chile on its western side. There aren't any huge cities nearby and the terrain is pretty rough.
