National Park Lauca


Located 186 km. from Arica and 12 km. de Putre. This is one of the highest altitude parks in the world, lying between 3,200 and 6,342 metres above sea level, with an average altitude of 4,500 metres. It covers an area of 137,833 hectares, including Chilean areas of the Andes and the Altiplano in the far north of the country. It was designated a Forest Reserve in 1965 and in 1970 it was declared a National Park. It is managed by the National Forestry Corporation (Conaf).

Because of the altitude, there is rainfall in summer and snow in winter. The average temperature is between 12°C and 20°C during the day and -3°C to -10°C by night. Despite these conditions, the climate is relatively dry.

Natural Attractions

The Cotacotani Lakes: This is a series of interconnected lakes with waters of a striking emerald colour, covering an area of approximately 600 hectares. They were formed by volcanic activity, which trapped water flowing from Chungará Lake to Cotacotani through subterranean passages. The water flows on, also underground, to the Parinacota marsh, where the Lauca river rises.

Chungará Lake:Covers 2,100 hectares at an altitude of 4,570 metres, making it the highest lake in the world. The waters are emerald green in colour and it is surrounded by snowy peaks including Parinacota, Sajama, Quisiquisini and, further south, the Quimsachatas, including Guallatiri volcano. There is attractive wildlife and the waters, although cold, are fine for a quick dip.

The flora varies with the altitude – the pre-cordillera and the Altiplano. Between 3,200 and 3,800 metres, in the sector known as the pre-cordillera, there is low scrub and cactus species such as the candelabra cactus and the tolar, the most typical vegetation of this zone. In protected areas and gullies there are thickets of queñoa and llareta.

Above 3,800 metres, in the Altiplano, there are two types of vegetation cover, depending on whether conditions are dry or wet. The predominant vegetation is queñoa de altura and other species such as tuna, llareta, paja brava, chachacoma and bofedal. The latter is a sort of marsh vegetation which only grows above 4,000 metres altitude.

The most striking aspect of the park is the fauna. Larger species include vicuñas, guanacos and huemules or Andean deer. There are also masses of vizcachas among the rocks. Around human settlements, large flocks of llamas and alpacas can be seen.

Some 130 species of birds can be observed, the most important being the giant coot, the queltehue de la puna, puna duck, Chilean flamingo etc.

The landscape is irregular. There are a number of volcanoes including Parinacota (6,342), Pomerape (6,282), Guallatiri (6,060) and Acotango (6,050).

The Altiplano covers most of the central part of the park, and old volcanic calderas can be seen, for example Ajoya and Tejene, as well as lava fields such as Cotacotani.

The two principal rivers are the Lauca, which drains the Bofedal de Parinacota, and the Lluta which flows out into the Pacific Ocean. The main lakes are the Cotacotani Lakes, and Chungará, at 4,500 metres a.s.l. the highest in the world, covering an area of 21.5 square kilometres.

Cultural Aspects
It is still possible to see traces of various features of pre-Colombian cultures. The most important was that of the Inca people, who used to occupy the area. There are fossils which were found in the area of Las Cuevas which are thought to be around 9,000 years old.
The most important archaeological sites are: the Chungará Tambo, the rocky retreat of Las Cuevas and the Inca Chacus of Las Cuevas.

Of great interest is the church at Parinacota, which displays a combination of colonial and indigenous cultures; the village of Chucuyo still consists of straw-thatched houses built of adobe; the farmlands of Chungará, Ajata and Cruzane exemplify the small territories which were held by a family or ayllu.

Excursion Trails
There are a number of trails in the Park, from which the landscape, the vegetation and the fauna of the pre-Cordillera and the Altiplano can be appreciated in all their majesty. One is the Cotacotani Excursion Trail, 8 km. There are four stops on the trail, from which you can see the village of Parinacota, queñoa woods, llareta clumps, marshes, camelid species and geo-morphological phenomena such as the Payachatas volcanoes and the Cotacotani lava field.

Another path, named Chungará, runs for 1000 metres along the shores of the Chungará lake. There are three stopping points on the trail offering views of the Payachatas, Quisiquisine and Quimsachatas volcanoes, and a great variety of birdlife such as giant coot, puna duck and white-tufted grebe.
