The Río Simpson National Reserve gets its name from the Río Simpson, which crosses the park on its westward trek toward the Pacific. The protected park encompasses 40,452 hectares (99,959 acres) of wilderness, including peaks that rise about 1,600 meters (5,248 feet) above sea level. Along with the Simpson, you can discover two of its smaller branches, the Correntoso and Cascada de la Virgen rivers, as well as forests filled with many tree species that are found only in Patagonia. If you are a fly fisherman, you’ll want to find a place on the bank of one of the waterways to cast a line. If you are more interested in just taking in the scenery, the park abounds in waterfalls and dramatic canyons; the wildlife found here includes pumas, pudus, foxes and a number of different bird species.
