You step out of the van into thin, cold air as dawn cracks over the eastern flank of the Salkantay range. The trailhead at Soraypampa feels raw and immediate: the wind pushes across tussock grasses, and the path rises in steady switchbacks toward a turquoise mirror cupped below a glacial lip.

moderate
Duration
10–12 hours (full‑day tour with transfers)

History
The Salkantay massif is an important Andean landmark in Quechua cosmology; trails in this area were used for centuries for trade and ritual travel before becoming trekking routes.
Conservation
High‑altitude wetlands and alpine grasses are fragile; stick to established trails, avoid disturbing wildlife, and carry out all trash to limit erosion and pollution.

Acclimatize before you go
Spend 24–48 hours in Cusco or a similar elevation to reduce acute altitude effects—avoid heavy exertion the first day.
Bring sun protection
Strong high‑altitude UV makes sunscreen, sunglasses, and a brimmed hat essential even on cloudy days.
Use walking poles
Poles cut perceived effort on steep climbs and protect knees on the descent; tours often provide sticks, but bring your own for comfort.
Watch for rapid weather changes
Afternoon storms are common—start early and carry a waterproof shell to avoid hypothermia and trail slickness.
Insulating midlayer
Warm fleece or down for cold mornings and gusty afternoons at 4,000+m.
Sturdy hiking boots
Support and traction for steep, rocky switchbacks and potentially muddy sections.
Sun protection (sunscreen, hat, sunglasses)
High UV exposure at altitude makes full sun protection mandatory.
summer
Light waterproof shell
Wind and sudden rain or sleet are common—pack a breathable shell for protection.
