When we arrive in Cusco, the body needs time to adapt to the altitude. At more than 3,300 m a.s.l., it’s normal for some people to feel discomfort during the first few hours or days. That’s why, before starting tours and hikes, it’s a good idea to understand what altitude sickness is, how it shows up, and what to do if it appears. The goal is to travel informed, take care of ourselves from day one, and enjoy the trip without complications.
What is “soroche” or altitude sickness?
Altitude sickness is the body’s response to the lower amount of oxygen at high elevations. It happens when we go up quickly from low areas without time to adapt. It doesn’t affect everyone in the same way: age, physical condition, and how fast we start activities all play a role. That’s why, when planning the itinerary, it’s always best to start with easy days and listen to your body.
What are the symptoms of altitude sickness in Cusco?
Recognizing the symptoms early helps us act quickly and keep them from getting worse.
Mild symptoms
These usually appear during the first few hours. The most common are headache, tiredness, light dizziness, a feeling of shortness of breath when walking, and loss of appetite. In these cases, the best thing is to rest, stay well hydrated, and avoid intense physical effort on the first day.
Moderate or severe symptoms
These include strong headache, persistent nausea, vomiting, difficulty breathing even at rest, and marked weakness. If this happens, you should stop your activities, notify your guide or travel partner right away, and seek medical attention. It’s not the time to push through with the tour; your health comes first.
What to do if you get altitude sickness in Cusco
If symptoms of altitude sickness appear, the main thing is to slow down and take care of your body. It’s not about forcing the itinerary, but about adjusting it so you can continue your trip without complications.
Rest during the first 24 hours
On your first day in Cusco, it’s best to stick to gentle activities. You can stroll slowly around the city or simply rest at the hotel. Avoid running up stairs, long walks, or demanding tours. This pause gives your body a chance to adapt better to the altitude.
Stay properly hydrated
At high altitude we lose fluids more quickly, so it’s essential to drink water throughout the day. Ideally, take small, frequent sips. Warm infusions also help, always avoiding too much coffee or alcohol, especially on day one. This helps reduce fatigue and headaches.
Eat light meals
While you’re adapting, it’s best to choose foods that are easy to digest: soups, vegetables, rice, white meats, or fruit. Very heavy or greasy meals, and drinking too much alcohol, can increase discomfort and nausea.
Coca tea and natural remedies
Coca tea is a traditional drink that can help relieve mild symptoms such as headache or tiredness. Coca candies or Andean herbs like muña are also used, always in moderation. These methods can help, but they should be seen as a complement to rest and hydration, not a substitute.
Preventive medication (talk to your doctor)
Some travelers take medication to prevent or reduce altitude sickness, especially if they already know they tend to feel unwell at high elevations. The safest option is to talk to a doctor before your trip, especially if you have respiratory or heart conditions, or if you’re traveling with older adults.
How to prevent altitude sickness before your trip
Prevention starts even before you arrive in Cusco. If possible, avoid arriving with a packed schedule right away. Ideally, plan a relaxed first day with no demanding tours. Before traveling, keep yourself well hydrated, get good sleep, and avoid excess alcohol. If you have medical conditions, it’s best to consult your doctor about possible preventive medication. Once in destination, take things step by step: short walks, light meals, and listen to your body from the very beginning.
Is altitude sickness in Cusco dangerous?
In most cases, altitude sickness is mild and temporary when handled properly. With rest, hydration, and a slower pace, symptoms usually improve within one or two days. The risk appears when we ignore the body’s warning signs and keep pushing through demanding activities. That’s why, when designing the itinerary, we always prioritize time to adapt to the altitude: travelers who take care of themselves enjoy the trip more and avoid unnecessary complications.
How many days do you need to acclimatize in Cusco?
In general, the body needs between 1 and 3 days to adapt to the altitude. The first day should be relaxed, the second can include gentle activities, and from the third day on, you can add more demanding tours. That’s why, when we build itineraries, we always use Cusco as an acclimatization stop before going to higher-altitude destinations.
Frequently Asked Questions About Altitude in Cusco
Does everyone get altitude sickness?
No. Some people barely feel anything, and others have mild symptoms. It depends on each body, how quickly you ascend, and how much you rest at the beginning. It’s not directly tied to age or fitness level.
Do children adapt better?
In many cases, yes. Children often adapt faster, but you still need to keep a close eye on them, make sure they’re hydrated, and avoid strenuous activity on the first day.
Is it worse at Rainbow Mountain?
Yes, because you reach more than 5,000 m a.s.l. That’s why we recommend going only after you’re well acclimatized in Cusco and not choosing it as your first excursion.
Does coca tea really help?
It can help relieve mild symptoms, such as headache or tiredness. It’s not a cure, but it can be a good support when combined with rest and proper hydration.
