Nahuel Huapi National Park

Glacial lakes of impossible turquoise stretch to snow-capped peaks as far as the eye can see. Nahuel Huapi National Park unfolds around the gleaming city of Bariloche like a living oil painting: dense Patagonian lenga beech forest ablaze in autumn gold, mirror-calm bays reflecting the Andes, and hiking trails that wind up through wildflower meadows to ridgelines where condors patrol the thermals. This is Argentina oldest national park, and after more than a century, it still has the power to stop you mid-stride and steal your breath.

History of Nahuel Huapi National Park

The history of Nahuel Huapi is inseparable from that of Francisco Pascasio Moreno, the Argentine explorer and naturalist who mapped much of Patagonia in the late 19th century. In 1903, Moreno donated a parcel of land he had been granted by the Argentine government to the nation, on condition it be protected forever as a nature reserve. This act sowed the seed of what became, in 1934, the first official national park in Argentina, gazetted under President Agustin Justo. The park now covers approximately 705,000 hectares, straddling the Andes along the border with Chile.

The name Nahuel Huapi comes from the Mapuche language and translates roughly as Tiger Island, a reference to the large island at the eastern end of the lake. Mapuche people inhabited the region for centuries before European contact, and their cultural presence is still felt in place names throughout the Lake District. German and Swiss immigrants who arrived in the early 20th century gave Bariloche its Alpine architectural character; the park spectacular setting drew scientists, artists, and adventurers from across the world.

What to See

The park centrepiece is Nahuel Huapi Lake itself, a 550-square-kilometre body of deep glacial water whose multiple arms reach into different valleys, each with its own character. Boat trips to the forested Victoria Island, where a grove of North American sequoias towers above the native arrayanes, are among the most popular excursions. The Lakes Circuit, a multi-day crossing between Argentina and Chile via Lago Frias and Puerto Montt, is one of South America classic travel routes.

On land, the park offers hiking at all levels. The Cerro Tronador trail leads to the base of a 3,478-metre extinct volcano whose glaciers thunder and crack in the afternoon heat. The Arrayanes forest at the tip of the Quetrihue Peninsula is perhaps the most fairy-tale landscape in Argentina: smooth orange-and-cinnamon trunks of ancient myrtle-like trees forming a cathedral canopy over a silent path.

Lakes and Landscapes

Nahuel Huapi defining quality is its variety. Within a single day you can cross woodland where hummingbirds dart between fuchsia blooms, emerge onto rocky ridges above the treeline with 360-degree Andean panoramas, and descend to the lakeshore in time for a late afternoon kayak. In late February and March, the lenga beech forest turns red, orange, and gold in one of the most dramatic autumn colour displays in the southern hemisphere.

Wildlife is abundant though often elusive: the Andean deer (huemul), the park emblematic species and Argentina national animal, can occasionally be spotted at dawn on forested slopes. Foxes are more brazen, patrolling picnic areas. Ringed kingfishers work the lake margins, and in the backcountry, pumas leave their presence in pawprints and scratched bark.

Local Insights

What locals know that guidebooks do not always tell you:

• The Arrayanes forest walk at Quetrihue Peninsula is best done mid-week and early in the morning, before tour boats from Bariloche arrive and fill the narrow path.
• Rent a car rather than relying on tour buses; the Circuito Grande scenic drive covers 250 km of lake and mountain scenery that buses rush through in half a day.
• The municipal market (Mercado Municipal) in Bariloche sells local smoked fish, wild boar pate, and artisan chocolates at a fraction of tourist-shop prices.
• Cerro Campanario viewpoint can be reached by chairlift in 10 minutes and is widely considered one of the finest views in the world; go at golden hour.
• March and April are ideal months: autumn foliage peaks, crowds thin after summer, and hiking conditions are often more stable than in windy January.
