The area of San Martin de Los Andes has become wildly famous for its fly-fishing and somewhat famous for it's Red Stag hunting. So much so that when hunters hear of hunting these grande beasts in Argentina they invariably thing of the mountains of San Martin. But do they exist further South? The answer is "Yes", they do.
As far South as Trevelin Red Stag are found in good numbers as are wild boar. The difference, I believe, is that they are more difficult to see and therefore more difficult to hunt. The San Martin area is surrounded by high mountain desert. Seeing the stag is not a problem. If one travels further South he will find them amongst the forests of the Andes mountain range and Patagonian Steppe.
