A high-altitude day hike from Cusco rewards you with a turquoise glacial lagoon and dramatic views of Salkantay. Expect a steep 2-hour climb at 4,200 m, cultural context from Quechua highlands, and a long but doable 10–14 hour day including transport.
More ways to explore the area's outdoor wonders
Pre-dawn van lights pick you up in Cusco and the road unfurls west toward Soraypampa, the high alpine plain beneath Salkantay. By the time the world lights up, you’re stepping from a wind-scoured parking area onto a steep trail that rises through puna grass and scree. The climb presses lungs and legs; at the ridge the water below announces itself—an intense turquoise bowl cupped against the white flank of Salkantay.

Acclimatize first
Spend 24–48 hours in Cusco before the hike to reduce altitude sickness risk; hydrate and avoid heavy exertion on arrival day.
Layer for big temperature swings
Mornings are frigid, the climb warms you quickly, and the lagoon wind is cutting—bring an insulated shell and a windproof outer layer.
Use trekking poles
Poles help on the steep ascent and protect knees on the rocky, sometimes loose descent.
Carry extra water and snacks
Guides provide meals, but altitude increases caloric and fluid needs—carry at least 1–1.5 L of water and quick-energy snacks.
Insulated jacket
Cold mornings and glacier-fed winds make a warm mid-layer essential at the lake.
winter
Sturdy hiking boots
Ankle support and grippy soles help on rocky, uneven switchbacks.
Sun protection (hat, sunglasses, SPF)
High-altitude UV is intense even on cool days—protect skin and eyes.

Stabilize your pace on the steep ascent and decrease impact on the descent.
