Humantay Lake is a brilliant turquoise glacial lake high in the Andes, one of the most popular day trips from Cusco after Machu Picchu and Rainbow Mountain. Set at around 4,200 metres beneath the snowcapped Salkantay peak, it is reached by an early drive and a short but steep hike. The colour is astonishing, the altitude is real, and on a clear morning it is one of the most beautiful spots in Peru.

Humantay Lake Peru: Cusco’s Turquoise Day Trip
Humantay Lake sits at the foot of the sacred Salkantay mountain, its water coloured an intense turquoise by glacial minerals suspended in the meltwater. Humantay Lake Peru shot to fame on social media in the last few years and now rivals Rainbow Mountain as the second most popular day trip from Cusco. Despite the crowds, the setting, a mirror-still lake under a glacier and towering peaks, more than lives up to the photographs.
The visit is a long day: a pre-dawn pickup from Cusco, a drive of around three hours to the trailhead at Soraypampa, then a steep climb to the lake, time at the top, and the return. Many travelers pair the effort with the mystique of the place; local tradition holds it a sacred site, and some leave offerings of stacked stones on the shore.
Humantay Lake Altitude: What to Expect
The Humantay Lake altitude is the main challenge of the day. The lake sits at about 4,200 metres, and the trailhead itself is already near 3,900, so the hike gains height in air that holds far less oxygen than sea level. Expect to move slowly and stop often on the climb, even if you are fit; this is normal at this elevation.
As with any high-altitude outing in Peru, the key is to acclimatise first. Spend two to three days in Cusco, at 3,400 metres, before attempting Humantay, hydrate well, and use coca tea. Take the ascent at your own pace, and if the altitude hits hard, it is fine to turn back; the lower viewpoints still offer a glimpse of the lake.

How to Get to Humantay Lake
Knowing how to get to Humantay Lake is simple: almost everyone visits on an organised day tour from Cusco, which is by far the easiest option. Tours leave the city between around 4 and 5 in the morning, include transport, breakfast and lunch and a guide, and return by evening. The road to Soraypampa is long and rough, which is why independent visits are uncommon.
From the Soraypampa trailhead it is a hike of roughly two kilometres to the lake, but with a stiff climb of around 300 metres in altitude. Those who prefer can hire a horse for most of the ascent, walking only the final stretch. Bring water, snacks, sun protection, a rain layer and cash for the entrance fee and horse.
Best Time to Visit Humantay Lake
The best time to visit Humantay Lake is the dry season, from May to October, when skies are clearest and the turquoise water is at its most vivid under the sun. June to August are the busiest and coldest months, with frosty starts. The shoulder weeks of May and September or October balance decent weather with slightly thinner crowds.
The wet season, November to March, brings cloud, rain and the chance of snow that can hide the peaks and dull the colour, so it is the least reliable window for the view. Whatever the month, go early: mornings are clearest, and the lake is often at its stillest and most photogenic before the wind and cloud build.
Do You Have to Hike? Day Trip vs. the Salkantay Trek
For the classic Humantay Lake view, only the short day-trip climb is required, and that is how the vast majority of visitors see it. It is steep but brief, and horses can carry you most of the way up.
Humantay Lake also sits on the first day of the multi-day Salkantay trek to Machu Picchu, so trekkers pass it on a longer route over the mountains on foot. That is a serious multi-day expedition rather than a day out, and it is best planned as its own dedicated trek. For everyone else, the day trip from Cusco delivers the lake without the multi-day commitment.
Common Questions, Answered
How high is Humantay Lake?
Humantay Lake sits at about 4,200 metres, with the trailhead already near 3,900. Acclimatise in Cusco for two to three days first, and take the steep climb slowly.
How do you get to Humantay Lake?
Almost everyone visits on an organised day tour from Cusco, leaving around 4 to 5 a.m. The tour handles the three-hour drive to Soraypampa, and from there it is a short but steep hike to the lake.
Is the Humantay Lake hike hard?
The distance is short, about two kilometres, but the altitude and a 300-metre climb make it strenuous. It is manageable for most acclimatised visitors at a slow pace, and horses can carry you most of the way up.
What is the best time to visit Humantay Lake?
The dry season from May to October offers the clearest skies and most vivid turquoise water. The wet season can bring cloud, rain or snow that hides the peaks, so it is the least reliable time for the view.
Can you visit Humantay Lake as a day trip?
Yes. Humantay Lake is one of the most popular day trips from Cusco, done in a long single day. It also sits on the first day of the multi-day Salkantay trek for those doing the longer route.
Do you need to acclimatise before Humantay Lake?
Yes. Spend at least two to three days in Cusco at 3,400 metres before the 4,200-metre lake. Hydrate, use coca tea, and climb slowly to reduce the risk of altitude sickness.
In short, the Humantay Lake altitude of 4,200 metres is the real effort; how to get to Humantay Lake means an organised day tour from Cusco; and the best time to visit Humantay Lake is the dry season, when the turquoise water is at its brightest.
Humantay Lake pairs naturally with a wider Peru trip, and many travelers add the Galápagos to a longer South America route.

The Bottom Line
Humantay Lake is one of the great short day trips from Cusco: a turquoise glacial lake under a sacred peak, reached by an early start and a steep climb at altitude. Acclimatise first, go in the dry season, start early, and take the ascent slowly. Do that, and the lake at 4,200 metres is a genuine highlight of any Cusco stay.
