Aconcagua is the highest summit in South America and the highest mountain outside Asia.<\/strong> Its altitude is 6962 m. The classic Normal Route is not one of the hard technical lines, yet the ascent itself remains a serious high-altitude expedition: participants spend many days in thin air, live in tents, carry their personal equipment between high camps and wait for the right decision on weather and on the state of the team.<\/p>\n

This article is here to help you understand the mountain before choosing a programme: where Aconcagua is, how the routes differ, what the difficulty is made of, how acclimatisation works, what experience you need and what costs arise on top of the price of the trip. Exact dates, prices and lists of services are published separately on the pages for all Aconcagua programmes<\/a>.<\/p>\n

The main Mountain Guide programme on this mountain<\/strong> \u2014 the classic ascent of Aconcagua by the Normal Route in 17 days<\/a>: two high-altitude cycles and two reserve days. The tighter formats \u2014 12 days<\/a> and 7 days<\/a> \u2014 require recent, confirmed acclimatisation. Current dates and prices are published on the page for the programme you choose.<\/p>\n

Where Aconcagua is<\/h2>\n

Aconcagua stands in the Central Andes, in the Argentine province of Mendoza, not far from the border with Chile. For most expeditions the city of Mendoza is the main arrival and preparation point. Equipment is checked there, organisational matters are settled and the overland part of the route begins.<\/p>\n

The classic approach runs up the Horcones valley. After registering and entering the provincial park, the group climbs to Confluencia and then continues to base camp at Plaza de Mulas. This is not a short walk in to the summit but part of the acclimatisation process. Altitude increases gradually, and each stage has a job of its own.<\/p>\n

The mountain lies within a protected area. A permit is required, matching the route and the length of stay. The opening dates of the offices, the application process and the fees can change from season to season. Old trip reports, forum threads and last year’s receipt are therefore no substitute for checking the current conditions. The detail is covered in the article on the Aconcagua permit and logistics<\/a>.<\/p>\n

If you want a short geographical answer with a map and an explanation of why people fly to this Argentine mountain via various cities, open the separate article “Where Aconcagua is”<\/a>. Here geography is covered only so far as it affects the expedition.<\/p>\n

Why the altitude of 6962 m matters more than the technical grade<\/h2>\n

Aconcagua’s altitude is 6962 m. Even someone in excellent shape receives considerably less available oxygen at that height than at sea level. The body cannot compensate for this through willpower or training alone. It needs time to adapt, and the outcome depends on individual response, quality of sleep, rate of ascent, nutrition, recovery and previous high-altitude experience.<\/p>\n

This is precisely why the phrase “technically straightforward mountain” is misleading. It describes the character of the classic ground in ordinary conditions, but it promises nothing about how you will tolerate nearly seven thousand metres. The difference between geographical altitude, the height gained along the route and the real physical load is examined in detail in the article on the altitude of Aconcagua<\/a>.<\/p>\n

At altitude, decisions come more slowly, sleep deteriorates, appetite falls and muscles recover more slowly. A simple everyday task takes longer. An experienced participant therefore organises clothing, water and equipment in advance, wastes no energy on unnecessary actions, and tells the guide about any change in condition before it becomes critical.<\/p>\n

How hard is the ascent of Aconcagua<\/h2>\n

On the Normal Route in typical conditions there is no obligatory sustained technical climbing and no travel across a snow-covered glacier. But the absence of hard climbing does not turn the route into a walk. Its difficulty is made up of several factors acting at the same time:<\/p>\n
