Although Humantay Lagoon can be visited throughout the year, the best time to do so is between the months of May to September, which corresponds to the dry season in the Cusco region. During this period, the weather is more stable and the chances of rain are lower, ensuring clear skies and a better view of the lagoon and the surrounding area.
On the other hand, between November and March, it is the rainy season in Cusco, which can make the road more slippery and the lagoon not look as spectacular due to cloud cover. If you decide to visit during this time, be sure to wear waterproof clothing and be prepared for abrupt changes in weather.
