Lanín National Park

Where the volcanic spine of the Andes plunges into Patagonian steppe, Lanín National Park sprawls across nearly 4,700 square kilometers of one of Argentina's most visually arresting landscapes. The park's centerpiece is Volcán Lanín itself, a 3,776-meter stratovolcano whose symmetrical cone dominates the horizon, its upper slopes cloaked in permanent ice and snow. Yet the park encompasses far more than alpine terrain: dense southern beech forests clothe the lower western slopes, their cathedral-like canopies filtering dappled light onto mossy forest floors, while eastward the terrain transitions into windswept steppe and grassland dotted with native southern conifers. This ecological gradient—from temperate rainforest to subalpine meadow to arid shrubland—creates a mosaic of habitats that supports a rich diversity of wildlife. Birds of prey hunt the open country and forest margins; woodland songbirds and small forest mammals inhabit the beech groves; waterfowl and wading birds frequent the glacial lakes and streams that thread through the park, their waters so crystalline they seem almost unreal. Guanacos, the wild relatives of the llama, move across the steppe in loose herds, while smaller mammals shelter in the forests and rocky outcrops.
