At 6,962 meters (22,841 ft), Cerro Aconcagua is the highest mountain in the Americas and the highest peak in the Western and Southern Hemispheres. Aconcagua lies 70 miles northwest of Mendoza and 9 miles east of the Chilean border.
Roughly 7,500 climbers attempt the summit each year, yet only 20% summit. Though Aconcagua is technically an easy climb if approached from the north, the altitude and the perception that it’s easy can cause problems. The atmospheric pressure is 40% of sea level at the summit. Ill prepared and poorly acclimatized climbers and tourists manage to get themselves into trouble every year.
In terms of equipment, there are no permanent snowfields on the Normal and Polish Traverse routes, but crampons and ice axe may be required in certain sections.
The most popular route is the Normal Route. The second most frequented route is the Polish Glacier Traverse route, which approaches the summit through the Vacas valley. The third most popular route is the Polish Glacier itself. Both of these routes are much longer.
The routes to the peak from the south and south-west ridges are extremely difficult.
