What to Expect When Trekking in the Andes in 2026

• Best seasons vary by region: May to September is strongest for Peru and Bolivia; November to March is best for Patagonia in Chile and Argentina.
• Altitude matters: many Andean treks travel above 3,000 m, so build acclimatization days into any itinerary that starts in Cusco, Huaraz, La Paz or Quito.
• Permits and logistics can shape the route: the Inca Trail requires advance permits and licensed guides, while Patagonia routes often need early lodging or campsite reservations.
• Guided trips are the best fit for remote high-altitude routes, language support, permits, transfers, emergency planning and local cultural context.
• Packing should cover sun, cold nights, rain and wind in the same trip; layered clothing and broken-in hiking boots are essential.
• Plan around regional access: some high passes are seasonal, and weather can change quickly even in dry-season months.
