Created in 1937, one of Southern Patagonia's major sites extends across an area of 600 000ha and is home to almost invincible peaks such as Cerro Torre and Fitz Roy; Perito Moreno, a dazzling blue-tinged glacier; and Lago Argentino, a vast glacial lake. The Los Glaciares National Park is a UNESCO World Heritage Site that will truly take your breath away and is an unmissable stop along the legendary Ruta 40.
