If you’re thinking a lot about choosing the Rainbow Mountain or Humantay Lake, it’s essential to consider that both routes involve high-altitude hiking.

HUMANTAY LAKE OR RAINBOW MOUNTAIN? IS ACCLIMATIZATION MANDATORY?
When people face altitude hiking trails, they must acclimate well before embarking on or taking part in what they really want to do.
To tell the truth, there is no magic or scientific formula to acclimate because it is a matter of time, and each person has his own proper time to climate themselves.
Therefore, if you have just arrived in Peru and have traveled directly from Lima to Cusco, your body will not yet be comfortable with the altitude, which is why we recommend acclimatizing for at least 02 days in the city of Cusco.
To properly acclimate, keep the following tips in mind:
- Take the time necessary to acclimatize to the altitude for 01 or 02 days before embarking on visiting Humantay Lake or Rainbow Mountain.
- Consult a doctor about any recommended medications that may help you adapt to high altitudes. Always consider allergic and forbidden medicines for you.
- Incorporate coca tea into your routine, a natural remedy made from coca leaves and traditionally used by local inhabitants to counteract altitude sickness, hunger, and thirst over generations.
- Avoid eating heavy meals, alcoholic drinks, and smoking.
- Make sure you stay properly hydrated.

SIMILARITIES BETWEEN BOTH HIKES
BEST SEASON
Rainbow Mountain or Humantay Lake, if we compare the best season to do both, which is better?
Furthermore, as both are located within the Cusco region, close to the Andean Mountain Range, they share roughly similar climates and the best time to visit.
We recommend doing both hikes during the dry season, which runs from April to November. During this period, you can enjoy sunny days, although the nights can be colder than in the wet season, but there is a slight chance of rain.
RENTING A HORSE
The hikes to Lake Humantay and Rainbow Mountain allow you to rent horses along the route. If you think you won’t be able to complete the route or simply want to enjoy landscapes without putting in too much effort, hiring a horse is better.
However, consider the following tips:
- On both excursions, whether Humantay Lake or Rainbow Mountain, you will have options for renting horses at the beginning, middle, or the returning way; with an approximate cost of 25 USD.
- It is important to remember that in the final stretch, the hike to Rainbow Mountain is steep, and people have to walk anyway because horses do not cover this section.
- Likewise, the Humantay Lake hike’s final stretch is too steep compared to the Rainbow Mountain hike. That’s why you will have to walk no matter what.
