More ways to explore the area's outdoor wonders
You crest a final switchback and the lake appears — a pocket of turquoise cupped by glacial moraine and the shoulder of snow-dusted Salkantay. At over 4,100 meters the air is thin, cold and bright; the lake’s surface reflects a sky that seems closer than it does in Cusco.

History
The area lies on traditional Quechua routes near the Salkantay massif, a mountain venerated as an Apu in local cosmology and historically used for seasonal grazing.
Conservation
Fragile alpine vegetation and thin soils recover slowly; stay on established trails, pack out trash and avoid trampling mosses and lichens.

Acclimatize before you go
Spend 1–2 days in Cusco or at moderate elevation to reduce altitude sickness risk; hydrate and take it slow on the ascent.
Layer for rapid weather shifts
Bring breathable base layers plus an insulated jacket and waterproof shell — conditions can change from sun to sleet in an hour.
Footwear matters
Choose sturdy hiking boots with good traction; sections include stone steps and loose scree where ankle support helps.
Bring cash for local snacks
Small vendors and tip jars at trailheads or restaurants may not accept cards — a few soles helps for drinks and snacks.
Water (2–3 liters)
Hydration is critical at altitude to reduce fatigue and altitude symptoms.
Sturdy hiking boots
Provide traction and ankle support on rocky, uneven trail sections.
Insulating jacket & waterproof shell
Protects against wind, rain and sudden temperature drops near the lake.
Sun protection (sunglasses, SPF, hat)
High-altitude UV is intense; protect skin and eyes even on cool days.
