How to Prevent Altitude Sickness in Cusco: 9 Practical Tips

Cusco is located at about 3,400 m (11,150 ft) above sea level, and most travelers feel the altitude when they arrive. Headaches, shortness of breath or tiredness are common during the first day. The good news: with a few simple habits, you can reduce the risk of altitude sickness in Cusco.

1. Take it easy on your first day

Rest after arriving, walk slowly and leave the big excursions for the following days.

2. Start lower, in the Sacred Valley

The Sacred Valley is lower than Cusco. Many itineraries spend the first nights there to help the body adapt gradually.

3. Drink plenty of water

The air in the Andes is dry. Stay hydrated throughout the day.

4. Eat light meals

Choose soups and light dishes during the first days, and leave heavy meals for later.

5. Try coca tea

Coca tea (mate de coca) is a traditional Andean drink offered in most hotels in Cusco.

6. Avoid alcohol at first

Alcohol can intensify the effects of altitude. Save the pisco sour for your second or third night.

7. Sleep well

Good rest makes a big difference. Choose a comfortable, quiet hotel.

8. Plan treks after acclimatizing

If you are hiking the Inca Trail, Salkantay or Rainbow Mountain, spend at least two days in Cusco first.

9. Talk to your doctor before traveling

If you have a medical condition, ask your doctor for advice before your trip. And if symptoms become severe, descend and seek medical attention.

Our itineraries, like the Cusco and Machu Picchu 4 Days Tour, are designed with acclimatization in mind.
