Torres del Paine National Park

National park in southern Chilean Patagonia

Torres del Paine National Park (lang es) is a national park encompassing mountains, glaciers, lakes, and rivers in southern Chilean Patagonia. The Cordillera del Paine is the centerpiece of the park. It lies in a transition area between the Magellanic subpolar forests and the Patagonian Steppes. The park is located north of Puerto Natales and north of Punta Arenas. The park borders Bernardo O'Higgins National Park to the west and the Los Glaciares National Park to the north in Argentine territory. Paine means "blue" in the native Tehuelche (Aonikenk) language and is pronounced PIE neh. It was established as a National Park in 1959. Torres del Paine National Park is part of the Sistema Nacional de Áreas Silvestres Protegidas del Estado de Chile (National System of Protected Forested Areas of Chile). In 2013, it measured approximately She and her party are sometimes credited as being the first "foreign tourists" to visit the area that is now called Torres del Paine National Park. Several European scientists and explorers visited the area in the following decades, including Otto Nordenskiöld, Carl Skottsberg, and Alberto María de Agostini. as Parque Nacional de Turismo Lago Grey (Grey Lake National Tourism Park) and was given its present name in 1970. In 1977, Guido Monzino donated 12,000 hectares (30,000 acres) to the Chilean Government when its definitive limits were established. The park was designated a World Biosphere Reserve by UNESCO in 1978.

In 1985, a tourist started a fire that burned about of the park. The blaze affected the areas east and south around Lake Pehoé. including about 2 km2 of native forest. The Czech government offered aid after the fire and donated 1 million to reforestation efforts. In late December 2011 through January 2012, an Israeli backpacker was charged of having started a fire after being caught by a park ranger when lighting up some paper roll in a forbidden area. The backpacker and his family have denied the charges. Subsequently, the Chilean authorities dropped the charges. The fire burned about of the reserve, destroying about 36 km2 of native forest and affecting most of the areas around Lake Pehoé and the western areas around Lake Sarmiento, but moving away from the Cordillera del Paine, the park's centerpiece. In 2019 an incipient wildfire caused by a cigarette butt was promptly extinguished by nearby fire brigades of the National Forest Corporation. Nevertheless, recent paleoenvironmental studies performed within the Park indicate that fires have been frequent phenomena at least during the last 12,800 years.

According to the Köppen climate classification, the park lies in the “temperate climate of cold rain without a dry season." The meteorological conditions of the park are variable due to the complex orography. The park is famous for its strong winds. The windiest months are November January, which coincides with the peak tourism season.

The zone is characterized by cool summers, with temperatures lower than during the warmest month (January). Winter is relatively cold, with an average high temperature in July of , and an average low of .

The rainiest months are March and April, with a monthly average rainfall of 80  mm. This represents double the July–October (winter) rainfall, which are the drier months. A study of the exact chemical components of the precipitation in the park has been carried out.

The park possesses a large drainage network, which consists of numerous rivers, streams, lakes, ponds, and cascades that come from the Southern Patagonia Ice Field and flow towards the southeast until the Última Esperanza Sound that bathes the coasts of the city of Puerto Natales. The courses of water come from a longitudinal profile and are very turbulent with brusque changes in course, generated by waterfalls and rapids. The Southern Patagonian Ice Field takes up the entire western side of the park. The Southern Patagonian Ice Field feeds four main glaciers; they are from north to south the glaciers: Dickson, Grey, Zapata, and Tyndall. This last glacier is rapidly receding. The largest is Glacier Grey. It is divided into two arms, because of the appearance of a peninsula of ice, commonly called the Island or Nunatak, that becomes apparent a little more with each year that passes. The eastern arm measures about 1.2  km while the western has a width of around 3.6  km. The longitude of the glacier in its path towards the interior of the park is 15  km. Studies of the glaciers in the park have given scientists a clearer picture of the epochs of the earth, or what happened after the last glacial age.

The landscape of the park is dominated by the Paine massif, which is an eastern spur of the Andes located on the east side of the Grey Glacier, rising dramatically above the Patagonian steppe. Small valleys separate the granite spires and mountains of the massif. These are: Valle del Francés (French Valley), Valle Bader, Valle Ascencio, and Valle del Silencio (Silence Valley). The head of French Valley is a cirque formed by tall cliffs. The colossal walls of Cerro Cota 2000 and Cerro Catedral punctuate the western region of the Valley. Cerro Cota 2000 is named for its elevation; its highest contour line is about Cerro Catedral is named so because its east face resembles a cathedral's facade. To the north stands the granite arête called Aleta de Tiburón (English: Shark's Fin). To the east, from north to south, lie the peaks Fortaleza (Fortress), La Espada (The Sword), La Hoja (The Blade), La Máscara (The Mummer), Cuerno Norte (North Horn), and Cuerno Principal (Main Horn). In the Valley of Silence, the gigantic granite walls of Cerro Fortaleza and Cerro Escudo (Shield Mountain) stand face to face with the western faces of the Torres del Paine. Ascencio Valley is the normal route to reach the Torres del Paine lookout, which is located at the bank of a milky green tarn. The highest mountain of the group is Paine Grande, whose height was measured in 2011 using GPS and found to be
The Southern Patagonian Ice Field mantles a great portion of the park. Glaciers include the Dickson, the Grey, and the Tyndall. Among the lakes are the Dickson Lake, Nordenskjöld Lake, Lake Pehoé, Grey Lake, Sarmiento Lake, and Del Toro Lake. Only a portion of the latter is within the borders of the park. All are vividly colored, most due to rock flour suspended in their waters. The main river flowing through the park is Paine River. Most of the rivers and lakes of the park drain into Última Esperanza Sound via Serrano River.

Much of the geology of the Paine Massif area consists of Cretaceous sedimentary rocks that have been intruded by a Miocene aged laccolith. Orogenic and erosional processes have shaped the present day topography, and glacial erosion is mainly responsible for the sculpturing of the massif in the last tens of thousands of years. A good example of the latter is the Cuernos del Paine, whose central bands of exposed granite contrast strongly with the dark aspect of their tops, which are remnants of a heavily eroded sedimentary stratum. In the case of Las Torres, what once was their overlying sedimentary rock layer has been completely eroded away, leaving behind the more resistant granite. In June 2014, scientists uncovered fossils of at least 46 ancient specimens of nearly complete skeletons of dolphin like creatures called Ichthyosaurs which lived between 245 and 90 million years ago. The finding came after melting glaciers revealed new rock faces beneath. During the last glacial period glacier extent in the area peaked about 48,000 years ago, much earlier than for the more northern locations of Chiloé and Llanquihue. During the late Pleistocene and early Holocene a series of proglacial lakes existed in the Torres del Paine area. The last of these lakes, the Great Tehuelche Paleolake, covered what is now Sarmiento and Del Toro lakes plus a large area to east making Cazador Range a peninsula. The Great Tehuelche Paleolake vanished after being drained about 7,113 years before present. Ancient lake terraces marks the level attained by these lakes albeit great uncertainty exists regarding their evolution.

The last study of significant scope carried out concerning the flora of the park was realized by Pisano in 1974. This study examined four biotic zones that made up the territory of the park, determined by their vegetational type. Torres del Paine National Park is adorned with beautiful vegetation, including the evergreen Embothrium coccineum, which produces vivid red flowers grouped in corymbs, and Calceolaria uniflora, of striking shape and colors. The park has 7 documented species of Orchidaceae, including Chloraea magellanica. In the park 85 non native plant species have been recorded, of which 75 are of European origin and 31 are considered to be invasive. The park contains four vegetation zones: Patagonian steppe, Pre Andean shrubland, Magellanic subpolar forests and Andean Desert. The vegetation of the Patagonian steppe is dominated by Fescue species (mainly Festuca gracillima), which are resistant to harsh winds and weather conditions that are typical of the Patagonian region. Some of the dominant plant species of the Pre Andean shrubland are Mulinum spinosum (a cushion plant) and Escallonia rubra, which are frequently associated with other species, including Anathrophyllun desideratum and Berberis buxifolia. The Magellanic deciduous forest is home to various species of trees such as the Nothofagus pumilio and Nothofagus antarctica. Above the tree line in the Andean Desert, Escallonia rubra, Empetrum rubrum, and Senecio skottsbergii take the place of Nothofagus pumilio trees. A study on the beech trees and forest regeneration patterns in the park was published in 1992.

Guanacos are one of the most common mammals found in the park. Other mammals include foxes and pumas. It is also home to the endangered Chilean Huemul. The puma's predation on guanacos in the park has been studied. The park contains breeding populations of 15 bird of prey species and two others are likely reproducing here. Among them are Andean condor, black chested buzzard eagle, rufous tailed hawk, cinereous harrier, chimango caracara, magellanic horned owl, austral pygmy owl, to name but a few. Other birds occurring in the park include the Chilean flamingo, Darwin's rhea, coscoroba swan, black necked swan, Magellanic woodpecker, Magellan goose, and black faced ibis.

The national park has over 252,000 visitors per year. The Refugio locations also have campsites and tent for hire. Cooking with a camping stove is not permitted except in Refugio locations. Camping is only allowed at specified campsites and wood fires are prohibited throughout the park. Since October 2016, it is mandatory to book campsites or refugios before entering the park. For less adventurous visitors, there are several hotels located in and around the park. A good time to visit Torres del Paine is between October and April because there is less rain. But, during high season the entrance fee is more expensive than between May and September. Some of Torres del Paine National Park attractions are Paine horns which are a group of mountains 2000 meters high in the middle of the W trek. There is a view of Pingo Lake from de Grey Glacier. Hikers are not allowed to stray from the paths in the national park. The visitor impact on the park has been scientifically measured. A certified guide is required to access some parts of the park. Visiting the park is recommended between September and April, during the southern spring, summer, and early autumn. During summer, daylight hours are long given the southern latitude. Outside of this time frame, the weather becomes extreme for the majority of the public. During the southern winter, daylight dwindles to only 8 hours a day. The park has been elected as the 8th Wonder of the World by TripAdvisor.

The park can be reached by Chile Route 9, which is paved and connects Punta Arenas and Puerto Natales and continues as an asphalt road for 100 km and then becomes a gravel road. In the winter using tire chains is recommended due to unstable climatic conditions. The park can also be reached through maritime and aerial routes. There are buses that leave from Puerto Natales.
