How to Avoid Altitude Sickness in Cusco: 10 Proven Strategies That Work
The best way to deal with altitude sickness is to prevent it. Here are the most effective strategies:
1. Acclimatize Before Any High-Altitude Activity
The most effective way to reduce the risk is to give your body time to adjust.
Spend at least 2–3 days in Cusco before doing hikes like Humantay Lake or Rainbow Mountain. During this time, keep your activities light and avoid physical stress.
This single step can dramatically reduce symptoms. This is the most effective way when learning how to avoid altitude sickness in Cusco.
2. Start with Easy Activities (City Tour Cusco)
Instead of resting completely, we recommend doing light sightseeing.
A great option is the City Tour Cusco, which includes nearby sites like Sacsayhuamán and Qenqo. It’s a low-intensity activity that helps your body gradually adapt to the altitude.
This is one of the best ways to combine acclimatization with exploration. It helps your body adapt gradually while you explore the city.
3. Stay Consistently Hydrated
At high altitude, your body loses fluids faster.
Drink water regularly throughout the day—even if you don’t feel thirsty. Proper hydration helps your body transport oxygen more efficiently.
4. Try Coca Tea or Natural Remedies
Coca tea is widely used in the Andes to relieve mild altitude symptoms.
While it’s not a cure, many travelers report feeling better after drinking it, especially during the first days in Cusco.

5. Slow Down Your Pace
One of the biggest mistakes is trying to do too much too fast.
Walk slowly, avoid rushing uphill, and focus on steady breathing. This becomes especially important during hikes.
6. Eat Light and Easy-to-Digest Meals
Heavy meals can make symptoms worse.
We recommend:
- soups
- vegetables
- light carbohydrates
Eating light helps your body focus on adapting.
7. Consider Preventive Medication
Some travelers use medication like acetazolamide to prevent altitude sickness.
Always consult your doctor before taking any medication.
8. Get Quality Rest
Sleep is essential for acclimatization.
Even if your sleep is lighter at altitude, giving your body time to rest helps speed up adaptation.
9. Avoid Alcohol and Excess Caffeine
Alcohol can worsen dehydration and make symptoms stronger.
It’s best to avoid it during your first days in Cusco.
10. Listen to Your Body
Pay attention to how you feel.
If symptoms appear:
- rest
- hydrate
- avoid physical effort
Ignoring early signs is one of the main reasons altitude sickness gets worse.
