Turquoise at Altitude: Hiking to Humantay Lake from Cusco
A turquoise alpine bowl and a short, steep climb that rewards patience with glacial blues and Andean presence.
At first light the Andes breathe out a cold, silver air that stings your cheeks and clears the sleep from your head. The van lurches out of Cusco and the city—with its tiled roofs and morning markets—drops behind you; the road climbs through puna grasslands where grazing llamas look like punctuation marks across a woolly page. By the time you reach Soraypampa, the mountain you came for unmasks itself—Salkantay’s jagged flank and the humbler, glacial-sculpted Humantay peak framing a bowl where a turquoise pool sits like a coin tossed into the sky.
Trail Wisdom
Acclimatize First
Spend 24–48 hours in Cusco at lower exertion to reduce altitude sickness risk before attempting the hike.
Bring Sun Protection
High-altitude UV is strong—use SPF 50+, sunglasses, and a wide-brim hat even on cloudy days.
Hydrate and Snack
Carry at least 1–2 liters of water and electrolyte snacks to maintain pace and energy on the climb.
Consider a Mule for Steep Sections
Mule support is often available from the trailhead for those short on acclimatization or with knee issues.
Local Knowledge
Hidden Gems

Conservation Note
The lake’s color depends on glacial melt; stay on established trails, pack out waste, and avoid disturbing ritual offerings or fragile vegetation.
Humantay sits in the Salkantay corridor and is part of landscapes long inhabited by Quechua communities who regard surrounding peaks as sacred 'apus.'

Common Questions
How long is the hike and how much elevation do I gain?
The trail is roughly 6 km round trip with approximately 400–500 m of elevation gain from the Soraypampa trailhead; hiking time is typically 1.5–2 hours up and 1–1.5 hours down.
Do I need to acclimatize before this hike?
Yes—spend 24–48 hours in Cusco at low exertion to reduce altitude sickness risk; if you experience severe symptoms, descend and seek medical help.
Are guides and transport included?
Most operators include round-trip transport from Cusco, a guide, and lunch, but confirm specifics—some charge entrance fees separately or offer optional mule support.
Can anyone do the hike?
Physically active travelers who are properly acclimatized can usually manage, but those with respiratory or serious cardiovascular conditions should consult a doctor first.
Is there a permit or entrance fee?
There’s no special permit, but many operators include the day-use entrance fee to the Soraypampa/Humantay area—check before booking.
When is the best time of day to photograph the lake?
Early morning and late afternoon provide flattering light and calmer winds for reflections; arrive early to avoid crowds and harsh midday sun.
What to Pack
Light daypack, 1–2L water, layered jacket and wind shell, high-SPF sunscreen and sunglasses — for hydration, warmth, and UV protection at altitude.
Did You Know
Humantay is considered an apu (sacred mountain) by local Quechua communities, and the lake is fed by glacial melt from the Salkantay massif.
Quick Travel Tips
Book a morning departure; carry cash for small onsite fees; avoid alcohol the night before; confirm vehicle pickup location in Cusco.
Local Flavor
After the hike, return to Cusco’s San Blas neighborhood for roasted alpaca or local stews; San Pedro Market is ideal for a quick, authentic meal and to sample chicha morada and empanadas.
