The camp sites on the normal route are listed below (altitudes are approximate).
- Puente del Inca, 2,740m (8,990ft): A small village on the main road.
- Confluencia Camp, 3,380m (11,090ft): A camp site a few hours into the national park.
- Plaza de Mulas, 4,370m (14,340ft): Base camp, claimed to be the second largest in the world.
- Camp Canadá, 5,050 metres (16,570 ft): A large ledge overlooking Plaza de Mulas.
- Camp Alaska, 5,200 metres (17,060 ft): Called 'change of slope' in Spanish, a small site as the slope from Plaza de Mulas to Nido de Cóndores lessens. Not commonly used.
- Nido de Cóndores, 5,570 metres (18,270 ft): A large plateau with beautiful views. There is usually a park ranger camped here.
- Camp Berlín, 5,940 metres (19,490 ft): The classic high camp, offering reasonable wind protection.
- Camp Colera, 5,980 metres (19,620 ft): A larger while slightly more exposed camp situated directly at the north ridge near Camp Berlín, with growing popularity.
- Several sites possible for camping or bivouac, including Piedras Blancas (~6100m) and Independencia (~6350m), exist above Colera, however seldom used and offering little protection.
Below is some information about fastest known times on the ascent up Aconcagua.
Although Aconcagua is a massive peak, the normal route is non-technical, and makes conditions ideal for a speed ascent. If you don’t pass out from the lack of oxygen, a good trial runner could technically challenge the current records.
Andinist and Peruvian mountain guide Holmes Pantoja Bayona has made the round trip ascent and descent on the big A in 20 hours 35min. The previous record was held by the well known Argentinean mountain guide Willy Benegas of the North Face Team, who did the same trail in a little more than 23 hours.
Jorge Egocheaga's was claiming a much faster round trip time of 14:05:54. However, that has been called into question on the basis of there being no evidence at all for the claim.
A speed attempt on the Big A can be very dangerous as it is very high altitude. Without proper acclimatization a casual trail run up the Big A would not be a good idea.
