The morning air in Las Loicas bites with high-altitude clarity as riders gather at the Mapicsa Lodge Café. Saddlebags are checked, leather creaks, and local gauchos run through the day's plan before the first trot toward Mayllín Camp. Over five days you move through open volcanic plains, narrow mountain passes and across valleys that still show bands of ancient marine fossils.

Acclimatize before you start
Spend a night in Malargüe or Las Loicas to adjust to altitude and reduce risk of headaches at 3,400 m.
Wear closed riding boots
Sturdy ankle-supporting boots protect your feet in stirrups and on rocky trails.
Hydrate and salt wisely
High-altitude riding requires steady fluids and electrolyte replacement—carry a personal water bottle or bladder.
Protect against sun and wind
Wide-brim hat, UV sunglasses and windproof layers are useful for long exposed rides.
Riding boots with small heel
Protects your feet in stirrups and gives ankle support on uneven ground.
Layered clothing (base, insulating, shell)
Temperature swings are large—layers keep you comfortable during cold mornings and warm afternoons.
Hydration bladder or 1–2 L water bottle
Easy access to water while riding reduces dehydration at altitude.
Sun protection (sunglasses, SPF 50, lip balm)
UV intensity is higher at altitude—protect skin and eyes during long rides.
