The wind pushes across the puna as you crest a gravel saddle and the Ausangate peaks peel open the horizon—red-brown ridges, icy cornices and a distant band of rainbow-striped clay that makes everyone pause for breath. Over three days the trail moves from the village slopes at Upis (≈4,210 m) up and over two major passes near 4,980–4,995 m, past high lagoons and across windswept bofedales where vicuñas graze.

Fitness Level
Good aerobic base with previous multi-day trekking or high-altitude experience; able to hike 6–9 hours at sustained pace.
Wildlife
History
Ausangate is a sacred Apu in Andean belief and long served as a seasonal grazing zone for Quechua pastoralists; trails follow ancestral routes between communities.
Conservation
High-altitude wetlands are fragile—stick to established paths, avoid disturbing camelid herds, and the operator uses mule support to limit campsite impact.

Acclimatize before you start
Spend at least 48 hours in Cusco (3,400 m) with light activity to reduce acute altitude sickness risk before ascending to Upis.
Hydration and calories
Carry 2–3 liters of water daily and salty snacks—high-altitude exertion burns more calories and depletes electrolytes quickly.
Sun and cold protection
High UV plus cold winds means sunglasses, SPF 50 sunscreen, a brimmed hat and an insulated jacket are must-haves.
Pace the passes
On long days (22 km/9 hrs) set a sustainable walking rhythm, take short rests, and communicate early if anyone shows altitude symptoms.
Insulated down jacket
Keeps core temperature stable during cold nights and windy high passes.
Sturdy waterproof trekking boots (broken-in)
Necessary for rocky switchbacks, wet peatlands and occasional snow patches.
Hydration system with 2–3 L capacity
Ensures regular fluid intake at altitude and reduces dehydration risk.
Sun protection (SPF 50, sunglasses, wide-brim hat)
High-altitude UV is intense even on cold days; protection prevents burns and snow glare issues.
