6 Tips to Avoid Altitude Sickness in Cusco

Cusco is located in the middle of the Andes at 3,360 meters (11,023 feet) above sea level, which can be difficult for many visitors who are not used to this altitude on their first days. As a result, it’s not surprising that altitude can have a significant impact, where a lack of oxygen is the only thing that can keep you from enjoying your trip. Don’t waste one day feeling sick; prevent the altitude sickness before you reach Cusco with some tips from this article.

Keep in mind Cusco Treks Elevations

Altitude sickness could ruin your trip to Machu Picchu. People in a hurry who want to do the Inca Trail, Salkantay, or other treks frequently fly from Lima, which is at sea level. Then they find themselves in Cusco, at an altitude of 3360 m (11,023 ft). To put things into perspective, mountaineers enjoy climbing the «tres mils,» or 3000 masl, mountains. You can understand that Cusco is high, and from there you climb even higher because the Inca Trail crosses 4,215 meters (13,828 ft). The Salkantay Trek crosses the Salkantay Pass at 4,630 m (15,190 ft). There are some good «four thousand».

Our trekking experts always advise those interested in hiking different treks around Cusco to spend at least one day in Cusco, preferably two days, so that the body can adjust to the altitude.

What is the Altitude Sickness?

Sometimes called «mountain sickness,» altitude sickness is a group of symptoms that can strike if you walk or climb to a higher elevation, or altitude, too quickly.
It typically occurs above 2,400 meters and primarily affects people who are not accustomed to living in high altitude areas, typically less than 900 meters above sea level. If you are going to travel to mountainous countries such as Peru, Bolivia, or Nepal and you are going to visit places located at high altitude, such as Machu Picchu, the Salar de Uyuni, or the Aconcagua, you should be aware of altitude sickness, how to prevent and combat it, and what kind of symptoms it usually presents.

Symptoms of the Altitude Sickness in Cusco

All the symptoms of the Altitude Sickness normally occurs in the first hours after arriving in Cusco. As your body makes normal adjustments to adapt to the altitude of Cusco, you may experience a few symptoms that are bothersome but are not cause for concern. They include rapid (but still comfortable) breathing, shortness of breath with strenuous exercise, occasional short pauses in breathing while you sleep, and frequent urination. The last two symptoms are caused by a low carbon dioxide level, which causes brain and kidney adjustments.
The first symptoms that you could feel in the first 8 to 36 hours are:

  • Headache that is not relieved by over-the-counter pain medicine
  • Nausea or vomiting
  • Dizziness or lightheadedness
  • Weakness or fatigue
  • Difficulty sleeping
  • Loss of appetite

The two most serious consequences of altitude sickness are altitude pulmonary edema and altitude cerebral edema. In these cases, the outcome can be fatal if you do not descend to lower altitudes quickly.

Altitude Sickness symptoms


When you get a headache and at least one other symptom within 24 to 48 hours of moving to a higher elevation, it’s most likely altitude sickness. If you’re climbing, a more experienced climber may recognize the symptoms of altitude sickness and guide you to get help.
A healthcare provider will inquire about your symptoms, activities, and location if you have severe altitude sickness. The provider may perform a physical exam, including listening to your chest.

How to prevent the altitude sickness in Cusco

The main way to prevent or avoid altitude sickness is through acclimatization, that is, the progressive ascent to slowly adapt to the hypoxia of altitude. Even so, it is important to know that no matter how closely an acclimatization schedule is followed, it is possible that symptoms of altitude sickness may occur. The International Union of Mountaineering Associations (UIAA) recommends a maximum daily altitude increase of 500 meters once you reach 3,000 meters above sea level, taking a rest day without ascending every 3 or 4 days.
A good way to prevent altitude sickness is to stay hydrated by drinking at least 4 to 5 liters of water a day and to maintain a varied diet rich in carbohydrates. It is best to avoid alcohol, tobacco, and large meals.

7 Tips to avoid the altitude sickness in Cusco

1. Take it Easy

When you get to Cusco city, first try to rest and relax. You can do some sightseeing around the city of Cusco; there are several great spots that you can visit, such as museums, markets, or some churches, which will help you acclimate. Try to avoid going on a long day tour, as more of these are even higher than Cusco city.

2. Avoid drinking alcohol or smoking

These can all make symptoms worse. Avoid drinking alcohol or smoking during your first two days in Cusco; at the high altitude, these can do a lot of damage to your body. Trust us! Even one cocktail could tip you over the edge into a raging headache.

3. Drink plenty of water

Water will help you to acclimatize and recover really fast at this altitude; otherwise,  dehydration will make you feel worse. Make sure you drink more water than you normally do at home.

4. Drink Coca or Mint Tea

Nowadays, every hotel and accommodation in Cusco offers coca or muna mint tea; these leaves have been used since ancient times and have helped people with altitude sickness. They can help reduce headaches and fatigue associated with altitude sickness.

5.Climb higher slowly

If you have enough time, the Sacred Valley is the best place to stay for a few days. Due to its elevation of 2,900m (9,514ft), from here you can visit Machu Picchu. Cusco is at 3,360 meters (11,023 feet), and it can make a huge difference to stay a few days in the Sacred Valley.

6. Get a shot of oxygen

Oxishot is a small, dischargeable can that contains 8 liters of oxygen that you can take when you arrive in Cusco or anytime you need a boost.

How to combat the Altitude sickness in Cusco

In case you notice symptoms of altitude sickness, do not continue ascending, especially if you are planning to spend the night at a higher altitude. If the symptoms of soroche get worse, you should descend and rest until they disappear or go to a doctor. In the latter case, the doctor will almost certainly conduct tests such as a blood test, a chest X-ray, or an electrocardiogram. In many cases, they will prescribe oxygen and some medications for headache or insomnia.

Pills help

There’s one magic pill that will save you many of these troubles. It is called Sorojchi Pill and it contains acetylsalicylic acid, salophen and caffeine. This over-the-counter drug will help with your blood circulation and headache. If you’re feeling dizzy and nauseous, try Gravol, an over-the-counter pill to stop motion sickness. Take both pills an hour before landing in Cusco. Remember to consult your doctor about medicines you intend to take, and always read the labels.
