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.
