Argentina // Bariloche and the Lake District

Parque Nacional Nahuel Huapi

The main goal of any trip to Bariloche is to see the natural wonders contained within the PARQUE NACIONAL NAHUEL HUAPI, the doyen of the Argentine national park system. Protecting a glorious chunk of the Andean cordillera and its neighbouring steppe, its origins lie in a grant of seven thousand hectares of land made by Dr Francisco P. Moreno (known as “Perito” Moreno, “perito” meaning “expert”) to the national government in 1903 on the condition that it was safeguarded for the enjoyment of future generations. It has since grown a hundredfold in size.

Most of the park falls within the watershed of the immense Lago Nahuel Huapi, an impressive expanse of water that can seem benign one moment and a froth of seething whitecaps the next. Of glacial origin, it’s 557 square kilometres in area, but highly irregular in shape with peninsulas, islands and attenuated, fjord-like tentacles that sweep down from the thickly forested border region. The lake’s name comes from the Mapudungun (Mapuche tongue) for Isle (huapi) of the Tiger (nahuel) and refers to the jaguars that once inhabited regions even this far south. Rainfall is heaviest by the border with Chile, especially in places such as Puerto Blest and Lago Frías – the nucleus of the land donated by Moreno – where over 3000mm fall annually. This permits the growth of Valdivian temperate rainforest and individual species such as the alerce, here at the northernmost extent of its range in Argentina. Other species typical of the sub-Antarctic Patagonian forests also flourish: giant coihues, lengas and ñire among others.

A second important habitat is the high alpine environment above the tree line (upwards of 1600m), including some summits that retain snow all year. The dominant massif of the park is an extinct volcano, Cerro Tronador, whose three peaks (Argentino at 3410m; Internacional at 3554m; and Chileno at 3478m) straddle the Argentine–Chilean border in the south. Glaciers slide off its heights in all directions, though all are in a state of alarmingly rapid recession. The “thundering” in its Spanish name is not meteorological or volcanic, but refers to the echoing roar heard when vast chunks of ice break off its hanging glaciers and plunge down to the slopes below. Rainfall decreases sharply as you move eastwards from the border. Cypress woodland typifies the transitional semi-montane zone, and at the eastern side of the park you find areas of arid, rolling steppe. Snow can fall as late as December and as early as March at higher altitudes: it’s not advisable to hike certain trails outside the high season. Average temperatures are 18°C in summer and 2°C in winter. The strongest winds blow in spring, which is otherwise a good time to visit, as is the calmer autumn, when the deciduous trees wear their spectacular late-season colours.

The park has abundant birdlife, with species such as the Magellanic Woodpecker, the Green-backed Firecrown, the ground-dwelling Chucao Tapaculo and the Austral Parakeet. You’ll hear mention of rare fauna such as the huemul and the pudú, though you have only a slightly greater chance of seeing them than you do of spying Nahuelito, Argentina’s answer to the Loch Ness monster. Animals that make their home in the steppe regions of the park (guanaco, rheas and foxes) are more easily seen. Of the non-native species, the most conspicuous are the red deer (ciervo colorado) and the wild boar (jabalí), introduced by hunt-loving settlers. In an effort to cull their numbers, the authorities issue shooting permits, which continue to serve as a source of revenue for the park – expect to see roast boar and venison carpaccio on many a local menu.
