If this is your first time hiking the Aconcagua 360 route, you should familiarize yourself with the multiple items you may require and how they can assist you. Let us now take a closer look at these things:

  1. Dry Foods

Since trekking entails walking across several types of terrains throughout the day, you may quickly lose your energy and motivation to keep going. You should keep a few dry foods on hand in these situations to help give yourself the boost your body requires. You should choose foods high in vitamins and carbohydrates to keep you going longer. Furthermore, carrying these foods is efficient because of their small size.

A Guide to the Top Three Routes to Reach the Aconcagua Peak

Aconcagua peak stands at around 22,838 feet above sea level, and it has been recognized as one of the most beautiful mountain peaks in the world. Aconcagua is the tallest mountain peak outside Asia. Mountaineering enthusiasts may have heard about seven summits, and Aconcagua is one of those seven summits. You can plan your next mountaineering trip to Aconcagua if you have previous experience of climbing one or two of the seven summits.

Aconcagua treks have become popular due to the natural surroundings along the trekking route. Around 3500 people complete Aconcagua climbing successfully, though the success rate is pretty low. Bad weather and steep climbing routes are the main reasons behind the poor success rate.

Trekking Routes to Aconcagua

Climbers traditionally use three trekking routes to reach the Aconcagua mountain peak. The routes have specific names: the Normal Route, the Vacas Valley Route, and the Polish Traverse Route. All three routes are popular among trekkers. Moreover, all these routes have their pros and cons. It would help if you had a professional guide to select the right route according to your climbing experience and expertise.

Moreover, the weather should also consider choosing the right route to reach the Aconcagua peak. In the following section, you will find a brief guide to the trekking routes to Aconcagua.

  1. Normal Route

The normal route is the most popular trekking route to Aconcagua, and the route has fewer technical difficulties. Climbers occasionally need poles and crampons on this route, though weather conditions remain good during the climbing season. It takes around 18 days to complete the trek if you follow the normal route.

The best time for trekking along this route is between November and March. However, the weather can deteriorate anytime. The harsh icy winds will make the journey difficult. The normal and Polish Traverse routes meet around 1000 m below the summit. This last 1000-meter climb is the most difficult for the trekkers.

  1. Polish Traverse Route

The Polish Traverse Route starts from the eastern side of the mountain. According to the guides and experts, this route is more challenging than normal. You should choose this route only if you have years of training in climbing. Like the normal route, the Polish Traverse Route takes around 18 days to reach the peak. As stated above, the last 1000m of the route coincides with the normal route.

  1. Vacas Valley Route

The Vacas Valley Route is the second-most popular route of the Aconcagua guided climb. Also known as the Polish Glacier Route, this route offers amazing natural surroundings. However, the route is only recommended for experienced climbers. You will need ropes, harnesses, ice axes, crampons, and other important accessories for this route. Typically, it takes two days more to reach the peak if you choose the Vacas Valley Route over the normal route. The journey starts in the eastern region of the mountain.

So, these are the three routes to reach the Aconcagua peak. Make sure that you choose the perfect route to make your journey seamless and successful. Finding a professional guide for the journey is imperative.

Historical discovery on Aconcagua

Although part of the local population was used as labor, in general the dominated towns preserved their cultural autonomy, and there are few cases in which there are mixtures or influences detectable by archeology on the side that is today Argentine. Here the Inca only occurs along the roads and associated sites, and also in some fortified places (pucara) that only occur further north in the Cuyo area. In contrast, on the Chilean side the Inca presence is stronger, with permanent settlements such as Copiapó, Ovalle, Quillota and Santiago, as well as known fortifications at Cerro Mercachas (opposite the entrance to the road to Mendoza), at Cerro Chena to the south of the city of Santiago (which guarded the Maipo river valley), and in the “Cerro de la Compañía” in the Cachapoal river basin, recently discovered and studied. We have already said that this was the last effectively dominated area, after which the Mapuche or Araucanian sphere began. Observing a map, it is clear that ceremonial sites in general and high-altitude burial sites in particular, are Cerro Aconcagua associated with high sections of the Inca road network. Said in functional terms: where a transverse path connected both slopes of the Andes or other mountain ranges such as those mentioned above, a high and prominent hill was sought and chosen for ritual ascents that left as a vestige what we call sanctuaries of height. Clear examples are, among others, the PichuPichu hills (southern Peru), Licancabur (east of San Pedro de Atacama in northern Chile), Azufre or Copiapo, Incahuasi (in the last two beautiful statuettes were recently excavated and found), El Toro (at whose foot there is a path that crosses the Valeriano pass in the direction of the Huasco river valley), Las Tortolas, Mercedario, and Aconcagua, related to the southernmost section of the Inca “royal road” that – like the current international route – connected the Uspallata valley with the basins of the Aconcagua, Mapocho and Maipo rivers in central Chile.

The network of high altitude sanctuaries that extends for about 2,000 km. from the south of Peru to the center of Chile and the west of Argentina, constitutes an important proof of the Inca Aconcagua Ascents

domain over these regions, as is also the organized network of roads and dairy farms. It was at the service, above all, of trade, mineral transport, troop movements and chasquis or messengers. Also, on certain occasions, they were traveled by ceremonial retinues. Through their relationship with high-altitude sanctuaries, they reflect the importance of the religious factor in the expansion and in the life of this last great Andean empire. High mountain archeology was practically inaugurated with the mummy of El Plomo hill, excavated by treasure hunters in 195 I and whose research was directed by Dr. Crete Mostny (at that time archaeologist – head of the National Museum of Natural History of Santiago de Chile ), served as a basic model for further findings. Its interpretation as a product of a human sacrifice from the Inca era remains in force. (The calculated age for this toddler was 8 years). Significant parallels are observed with our Aconcagua burial: in addition to the geographical proximity to the southern border of the Empire and a similar height above sea level. the analogies are found in the ages of the sacrificed children and in their sex (male in both), in the richness of the textile garments, and above all in the statuettes: the golden flame and the two with Spondylus shells are practically identical to those Aconcagua Argentina

recovered on the summit of Cerro El Plomo. (This suggests the possibility that both ceremonies were held simultaneously). Between 1956 and 1968 Chilean climbers explored an artificially filled platform located on the very summit of Cerro Las Tortolas (6,300 meters), which provided a series of elements, even statuettes. In 1956 the Austrian Mathias Rebitseh extracted silver human statuettes from structures on the summit of Cerro Galan (Puna de Catamarca), carrying out three other expeditions to the area between 1958 and 1965, accompanied by Argentine climbers. For our part, together with collaborators from the Institute of Archeology and Ethnology of the U.N. Cuyo, we began in 1963 a series of explorations in the highlands of San Juan and western La Rioja. whose most spectacular result was the discovery of the mummy of El Toro hill (approximately 6,200 meters) by the climber Erico Groch accompanied by Antonio Beorchia. In the same year of, 1964, Peruvian climbers excavated a rich Inca tomb near the summit of the extinct volcano Pichu-Pichu in  ​​Arequipa (at 5,600 meters). But in this case, the body of a woman of about 15 was very poorly preserved. Other finds of high-altitude mummies in southern Peru are ancient, and the material has been lost (the case of Chachani hill), or they badly have dementia Aconcagua

(Coropuna). The latter also happens with a child of about six years of age. Found in 1905, with a simple trousseau, on the Charli hill (about 6,000 meters), on the eastern edge of the Puna de Jujuy, donated to the Ethnographic Museum of Buenos Aires.

Information to know to come to Aconcagua

A delicate task that has required a lot of time is that referring to the cleaning, conservation and analysis of the numerous textile pieces that made up the funerary bundle. The initial work was carried out by Professor Monica Ampucro de Guercio, with the advice of Lic. Julie Palma (then in charge of the respective section of the Chilean Museum of Pre-Columbian Art). After an interruption, they were taken up again in 1991 by Professor Clara Abal and Mr. Ferrari, who also had the advice of the Museum. With private funds, a Textile Laboratory was set up in the Faculty of Philosophy and Letters that allowed progress in these works in a technically adequate manner. This contribution to the cultural study of the Aconcagua burial should be especially highlighted. Some questions arise: how do we know that this burial corresponds to the Incas of Peru? When and why did these arrive to the northwest of Mendoza? Because it is supposed to be a human sacrifice, and what was the meaning of these practices Aconcagua Argentina


Let’s say first of all that the finding we are commenting on is one of the rare cases of “frozen mummies”, that is, well-preserved bodies for having been buried in places near high peaks of the Andes Mountains, at more than 5,000 meters Tall. In this way they differ from the numerous “drying mummies” that are usually found in the arid zones of the Peruvian coast and northern Chile. such as wood, leather, feathers, etc.). The second correspond to different times and cultures; On the other hand, the “high-altitude mummies” are, until now, exclusively attributable to the Inca Empire, which with its capital in Cuzco was formed and expanded in the fifteenth century and later fell under the troops of Francisco Pizarro in the year 1532.

Three of these finds come from the extreme south of this extensive empire, and are also the best documented archaeologically: Cerro El Plomo in central Chile (5,400 meters), Cerro El Toro in the NW of the province Aconcagua

of San Juan (approximately 6,200 meters) and Aconcagua hill in the province of Mendoza; here, not near the summit but in a place located at 5,300 meters. But there are also numerous other high-altitude sites, more or less complex, in which archaeological elements originating from pre-Columbian ritual practices have appeared. (Antonio Beorchia published a record of more than 100 of these places in 1987). The exploration and study of it have given rise to an original branch of research called «high mountain archaeology». These findings are notable not only for their content but also for what it meant for the indigenous people with their limited technical means to reach those heights (in two cases, the Mercedario and the Llullaiyaco, up to 6,700 meters) and even carry out constructions on them. . To locate them culturally we must say two words about the Inca expansion towards the South. From data collected How to Climb Aconcagua

by the chroniclers of the time of the conquest, we know that the imperial phase of the Incas (until then, a local kingdom with its capital in Cuzco) began in the year 1438 with the seizure of power by the Inca Yupanqui (whom he was given the title of Pachacuti (“renovator of the world”). Firstly, he defeated neighboring enemies; shortly after, he conquered the Colla kingdom and other smaller ones located around Lake Titicaca. With these and other territories (many of them integrated into the empire peacefully), the Tahuantinsuyo was organized, that is, the kingdom of the “Four Regions.” His son, Tupac Inca Yupanqui, continued the expansion towards the south of the Andean area, Mount Aconcagua

reaching in a few years (approximately between 1475 and 1480) the extreme reached: Uspallata valley in Argentina and Maipo and Cachapoal river valleys in Chile.These territories were integrated into the southern sector of the empire called Collasuyo, linked to each other and to Cuzco through the admirable network of paths s and roads that have recently been the subject of detailed studies. In northwestern Argentina and in Cuyo these trails are sometimes preserved (often long straight stretches, dotted with shelters or “tambos” (tampu) that today appear as small ruins of pircado enclosures. Numerous branches crossed the Cordillera or other high mountains such as Famatina in the province of La Rioja Another very interesting case is that of Aconquija, where a branch of the road that ascends from the Santa Maria valley (province of Catamarca) crosses that high mountain range and ends in a remarkable group of constructions located at 4,200 meters includes large squares for ceremonies and is crowned by an enclosure or square also of a symbolic or ceremonial nature on the summit of the nearby Cerro de las Cuevas, at almost 5,000 meters. such as this must have been associated with mining deposits, especially metals, whose search and domination was undoubtedly one of the reasons for the Inca expansion.

How to face an expedition to Aconcagua

As a preliminary step, we judged it convenient to carry out an act in which the expedition’s results were publicly reported, from the University’s headquarters, with the presentation of the materials found. This was carried out in the Rector’s Office of the National University of Cuyo on February 12, with the presence of its authorities. Thus, the fact that the University, (through the Institute of Archeology that had carried out the respective work), became the custodian and owner of those elements that from that moment became part of the Cultural Heritage of the University was legally sanctioned. Nation. There, the intention was announced to exhibit some day the set of materials from the Aconcagua burial in a specially equipped “Inca Room” in the Archaeological Museum of the Faculty of Philosophy and Letters. (Despite having an excellent project designed by the architects of the University, this purpose has not yet materialized). The initial laboratory work -and the most delicate- was to separate How to Climb Aconcagua

the elements that made up the funerary bundle. For this, we carried out preliminary work with the help of Chilean specialists who visited us at the end of March, led by the anthropologist Silvia Quevedo. For various reasons, it was necessary to wait more than a year for the completion of this delicate task, until, with the invaluable collaboration of Julie Palma and Luis Solar, from the Chilean Museum of Pre-Columbian Art (endowed with an important textile laboratory), the operation It was carried out during six tense days in May 1986. The various wrappings (a total of 25 large and small textile pieces) were removed with great care and precision, beginning with the crimped mantle of feathers and the plume that had remained seen in preliminary work. The advice on the medical-biological aspect was directed by Dr. Carlos de Cicco, professor at the Faculty of Medical Sciences and deputy director of the Medical-Legal Corps of Mendoza. In addition to abundant photographic documentation, a large part of the operation was filmed on video by the independent producer Alberto Marchesini, whose materials were used to make a television program of about 45 minutes that caused quite an impact on the public in various Argentine cities. Although deformed by strong lateral compression, the child’s body appeared well preserved. He was dressed in two “uncu” (tunic or “Andean shirt”, lacking sleeves) made of wool; He was wearing flip-flops made of wool and hair with vegetable fiber soles, and around his neck, he kept a necklace made up of multi-colored stone beads. Above it was a number of other textile pieces (cloaks, sashes, loincloths, cords, etc.). Some of the cloaks are made of cotton. They have a geometric decoration and stylized birds in the brocade technique, Mount Aconcagua

which corresponds to a tradition of the Peruvian central coast and that had never been found in other high-altitude sites. One of the blankets had been knotted at one of its ends, and inside it was found a very thin gold plate rolled up. The symbolism of this escapes us. The researcher J. Roberto Barcena has detected the presence of a reddish pigment in the body, probably obtained from the seeds of a tree that grows in the eastern forests of the Andes, called “bixa” or “achiote”. This practice, undoubtedly related to red as a symbol of life, has not been observed in other high-altitude mummies (except for the child from Cerro El Plomo in Chile, which shows traces of facial paint). To enable organic studies, an autopsy was performed (on the advice of the paleopathologist Dr. Enrique Gerszten), which Cerro Aconcagua was performed by Dr. De Cicco in August 1986. One of the results was to verify that the child had ingested a liquid as his last meal. reddish, also probably obtained from achiote (Barcena, 1989). Other researchers have carried out medical studies (in relation to the cause of death), histological, microbiological, genetic, etc., as well as environmental studies about the site: geological, paleo-climatic and pollen studies. In addition to body X-rays, a computed tomography test has been carried out under the direction of Dr. Juan Carlos Cruz. A maxillo-odontological study by Dr. Mario Guinazu has made it possible to set the age of the individual at 7 years (plus-minus 9 months). The weight of the mummy in May 1986 was 11 kg with 200 grams, slightly more than 1/ 3 of the estimated Aconcagua Ascents

original weight, product of a partial desiccation. The preservation of the body has been satisfactory. It remains stored in a freezer at an average temperature of about 10 degrees below zero. For various reasons, we have decided not to exhibit it publicly in the projected Sala Incaica of the university museum. It will remain in its refrigerated chamber, subject to the least number of manipulations possible, to be seen only by specialists and reserved for future studies. Instead, a replica will be exhibited, on which part of the clothing, the necklace and the sandals will be placed. In other showcases will go the other textiles and the accompanying trousseau.
