Humantay Lake emerges as a glacial gem in the Andean heights, captivating adventurers and seekers of transcendent experiences with its crystal-clear turquoise waters that reflect the majesty of the Humantay snow-capped peak. This natural sanctuary, located at 4,200 meters above sea level, represents one of the most photographed and revered destinations in the Vilcabamba mountain range.
Glacial origin and unique characteristics
The formation of this lake is a result of millennia of glacial processes, where the constant melting of the Humantay snowfield feeds this natural reservoir of intimate dimensions but extraordinary visual impact. The waters maintain an average temperature of 4°C throughout the year, preserving that characteristic turquoise color that results from specific mineral content and the reflection of sunlight on suspended particles.
The water mirror extends approximately 200 meters at its widest point, creating a perfectly smooth surface that doubles the image of the surrounding snow-capped mountains. This particularity makes each visit a unique photographic experience, where reality and its reflection merge into a visual symphony of epic proportions.
Prime location in the mountain range
Humantay Lake is strategically positioned in the Mollepata district, Anta province, within the Cusco territory. Its location at the foot of the namesake snowfield, which reaches an altitude of 5,473 meters, makes it a natural viewpoint towards one of the most imposing glaciers in the region.
From this special place, several giant mountains can be seen simultaneously, including parts of the impressive Salkantay snowfield, forming a grand natural theater of mountains where the lake is the main star of this incredible Andean landscape.

Best time to visit Humantay Lake
Timing your visit is crucial to maximize your experience at this high-altitude glacial destination. Each time of year offers distinctive characteristics that can completely transform your perception and enjoyment of this Andean natural sanctuary.
Arid season (April-October)
During these months, weather conditions favor exploration with predominantly clear skies and minimal rainfall. Early mornings register sub-zero temperatures, while midday sun can significantly elevate the thermal sensation. This thermal variability requires adaptable clothing but guarantees exceptionally clear photographs.
Rainy period (November-March)
The rainy season transforms the environment into a more dynamic and changing scene. Intermittent rainfall can create unique visual effects when clouds partially disperse, generating plays of light and shadow over the lake’s surface. Although visibility may be compromised, the colors of the landscape acquire extraordinary intensity and saturation.
Astronomical considerations
The months of June and July coincide with the southern winter solstice, providing the most intense light hours for the region. During this period, the solar position allows for optimal lighting of the lake between 10:00 AM and 2:00 PM, the ideal time to capture the chromatic contrast between the turquoise water and the immaculate white of the surrounding glaciers.
Tourist influx factors
May, June, and September experience the highest concentration of visitors, which can impact the experience of tranquility and contemplation. For those seeking more privacy, April and October offer a balance between acceptable weather conditions and lower tourist density.
Frequently asked questions about Humantay Lake
Is it possible to visit Humantay Lake without a guide?
While it is technically possible, it is highly recommended to have a local guide due to changing weather conditions, extreme altitude, and the importance of respecting the cultural traditions of the area. Specialized guides provide knowledge about safety, flora, fauna, and the spiritual significance of the site.
What level of physical fitness is required?
The hike demands a moderate fitness level. Although the distance is relatively short, the altitude of 4,200 meters and the uphill slope can present significant challenges. Previous experience in mountain hikes and cardiovascular preparation is recommended.
Can you swim in the lake?
Swimming or entering the waters of Humantay Lake is strictly prohibited. Reasons include the extremely low temperature (4°C), respect for the sacredness of the place for local communities, and the preservation of the fragile ecosystem.
How long can you stay at the lake?
Most tours allow between 30 to 60 minutes of stay. This time is sufficient to appreciate the beauty of the place, take photographs, and enjoy a moment of contemplation, considering that weather conditions can change rapidly.
Is it necessary to carry supplemental oxygen?
For visitors without pre-existing medical conditions, supplemental oxygen is not essential, although some tours offer it as a precaution. Prior acclimatization in Cusco and gradual ascent are more effective strategies for adapting to the altitude.
Is there horseback riding service for the ascent?
Yes, there is the possibility of renting horses for the ascent, especially recommended for individuals with physical limitations or altitude adaptation issues. This option should be coordinated in advance and incurs an additional cost.
Is camping allowed near the lake?
Camping is not permitted in the immediate vicinity of the lake for conservation reasons. However, there are authorized camping areas in Soraypampa, the base camp located 1.5 kilometers away.
What is the best time to visit?
The early hours of the morning (between 7:00 and 9:00 AM) offer the best conditions: lower probability of mist, calmer waters for perfect reflections, and more tolerable temperatures before solar radiation increases.
What to do in case of altitude sickness?
Mild symptoms include headache, nausea, and fatigue. It is recommended to rest, hydrate abundantly, and descend gradually. In severe cases with extreme breathing difficulty, intense dizziness, or persistent vomiting, it is imperative to descend immediately and seek medical attention.
