Acclimatize before the hike
Spend a day in Mendoza or a lower valley to reduce altitude effects and gauge your response to thin air.
Hydrate early and often
Carry 2–3 liters and sip regularly—altitude and dry air increase dehydration risk even if you don’t feel thirsty.
Protect against strong sun
Use a wide-brim hat, SPF 50 sunscreen, and UV-rated sunglasses—high-altitude sun burns faster.
Footwear and traction
Wear sturdy hiking boots with good ankle support for rocky, sometimes loose sections of trail.
