The park is situated in the transition zone between the Andes Mountains and the Gran Chaco lowlands, featuring varied topography ranging from 700 to 2,300 meters above sea level. The landscape is characterized by steep mountain ranges, deep valleys, and numerous watercourses. The area's geological formation consists primarily of sedimentary rocks from the Precambrian and Paleozoic eras, with significant limestone deposits. The park's complex terrain has created diverse microhabitats and ecological niches, contributing to its rich biodiversity.
El Rey National Park was established in 1948 to protect one of Argentina's most pristine subtropical forest ecosystems. The area was previously part of a large cattle ranch called Finca El Rey, from which the park derives its name. Before European colonization, the region was inhabited by indigenous peoples, including the Lule-Tonocoté groups. Archaeological sites within the park boundaries provide evidence of human settlements dating back several centuries. The park was created through a donation of lands by the Salta provincial government and currently covers 44,162 hectares (109,123 acres).
Key attractions within El Rey National Park include the Los Puestos Trail, which offers excellent wildlife viewing opportunities, and the historic ranch buildings from the old Finca El Rey. The park features several waterfalls, including the spectacular Cascada El Rey, and numerous scenic viewpoints overlooking the valleys. The Popayán River system provides important water resources and creates beautiful riverside environments. The park's remote location and limited access help maintain its pristine condition, though this also means visitors should plan their trips carefully and arrange necessary permits and guides in advance.
