Frequently asked questions about South America Andes mountaineering on Aconcagua (6,962 m / 22,841 ft). Supplemental answers align with the core FAQ and add expedition logistics detail.
Official answer: Yes. Every climber must obtain a permit from Parque Provincial Aconcagua before entering the park.
Apply in Mendoza with a valid passport, proof of rescue insurance, and a signed medical form. Permit fees vary by season and nationality.
Carry a printed permit copy at Confluencia (3,390 m) and Plaza de Mulas (4,350 m). Rangers check documents at park gates and base camps.
Most climbers plan a multi-week South America Andes mountaineering trip from Mendoza with time built in for acclimatization before the summit attempt.
A typical itinerary spans eighteen to twenty-one days round trip. That schedule includes two nights at Confluencia, four to five nights at Plaza de Mulas, and rotation nights at Camp Canadá (5,050 m) and Camp Colera (5,970 m) before a summit window.
Build at least two full rest days at Plaza de Mulas before moving above 5,000 m. Rushing the schedule increases withdrawal rates from altitude illness.
Climbers use Confluencia (3,390 m) and Plaza de Mulas (4,350 m) as the main base camps along the Normal Route.
Higher camps include Camp Canadá (5,050 m) and Camp Colera (5,970 m) before the summit push. Teams typically ferry loads between camps over several rotation days rather than carrying full summit kits in a single ascent.
Carry a four-season mountaineering tent rated for high winds, a −20 °C sleeping bag, and crampons compatible with double boots. Pack a satellite messenger or radio for Plaza de Mulas check-ins.
Review the park equipment list before leaving Mendoza. Rangers can deny entry if mandatory cold-weather gear is missing from your kit.
