General Information
What is the Choquequirao trek?
The Choquequirao Trek is a challenging hiking route, known for its high level of difficulty, spanning approximately 62 kilometers (38.5 miles) between the regions of Cusco and Apurímac. This trek takes you to Choquequirao, an archaeological site called the “sister of Machu Picchu” due to the similarities many travelers see between the two.
In 2024, this route was highlighted by the New York Times as one of the best places to visit, thanks to the mysteries hidden within the site and especially to the stunning views it offers along the entire journey.

Choquequirao is one of the destinations growing in popularity to the point of being known as Machu Picchu’s sister.
What is altitude sickness or “soroche”?
Altitude sickness or mountain sickness, also known as “soroche,” is a condition that occurs when the body does not adapt in time to the reduced oxygen at high elevations, such as in cases of altitude sickness on the Choquequirao trek. It usually happens when people make sudden ascents, like traveling from Lima to Cusco, and it can affect even those who are in good physical shape.
Symptoms of altitude sickness can vary, but in most cases, if you devote at least two days to proper acclimatization, the body adapts, and the effects of soroche—like altitude sickness on the Choquequirao trek—are minimal or may even disappear entirely.
Why does altitude sickness happen on the Choquequirao trek?
Altitude sickness is related to the amount of available oxygen at different elevations. As we climb higher, the concentration of oxygen decreases, making it more difficult for the body to obtain what it needs. This is especially noticeable above 1,500 meters (4,921 feet) above sea level, where oxygen becomes scarcer. This phenomenon is one of the main concerns when facing altitude sickness on the Choquequirao trek.
Why does it matter? Many travelers come from areas at much lower elevations, so when they make a sudden ascent, their bodies don’t have enough time to adjust to the new altitude. As a result, they don’t get the oxygen they’re used to, and that’s when the symptoms of altitude sickness begin to appear—a scenario that can also happen during the challenging altitude sickness on the Choquequirao trek.
What are the symptoms of altitude sickness?
It’s important to note that the symptoms of altitude sickness can vary in intensity from person to person, since each body responds differently. Below are the most common symptoms:
- Headache
- Dizziness
- Excessive fatigue
- Lack of appetite
- Difficulty breathing
- Difficulty sleeping
- Nausea or vomiting

If symptoms worsen or persist during your trip, seek medical assistance.
If you experience any of these symptoms and they become more intense over time, it’s crucial to consult a doctor. Doing so can prevent potential risks of altitude sickness from affecting your overall well-being.
At what altitude can altitude sickness appear?
Altitude sickness usually affects travelers coming from places at much lower elevations, such as those arriving from sea level.
Take the example of the Choquequirao Trek and the city of Cusco, both of which are over 3,000 meters (9,842 feet) above sea level. What does that mean? It means those arriving from significantly lower altitudes have a higher probability of experiencing symptoms of altitude sickness. This is why allowing your body adequate time to acclimatize upon arrival is essential—a process that typically doesn’t take long and helps prevent these issues.

Set aside one or two days to let your body adjust to the altitude—you’ll definitely need it!
Risks of Altitude Sickness on the Choquequirao Trek
How likely is it to suffer from altitude sickness on the Choquequirao trek?
Relax! It’s unlikely you’ll experience altitude sickness symptoms during your trip. Why? Because your body will probably have adapted to the area’s altitude due to prior acclimatization.
Moreover, travel agencies typically provide detailed information on this topic several days in advance and even upon your arrival. If not through the agency, you’ll most likely get recommendations at the hotel where you’re staying.
How to Acclimatize to the Choquequirao Trek Altitude
What altitudes will you reach during the Choquequirao trek?
To ease your worries about the altitude during the trek, it’s important to clarify that you won’t face extreme elevation changes. While it’s recommended to acclimatize in Cusco before starting, you’ll encounter relatively moderate altitudes along the route.
During the hike, you’ll reach the lowest point in Conoc, located at 1,760 meters (5,774 feet) above sea level, and the highest point in Choquequirao, at 3,050 meters (10,006 feet). Note! Cusco sits at 3,399 meters (11,152 feet), so if you’ve already acclimatized there, you shouldn’t have altitude-related issues regarding altitude sickness on the Choquequirao trek.
How does acclimatization help prevent altitude sickness?
This step is very important because it enables your body to adjust its functions. During acclimatization, your body increases the production of red blood cells, which carry oxygen throughout the body. In addition, your system adapts to capture more oxygen than it’s used to and increases blood flow to vital organs like the heart and brain.
This conditioning process happens within a few days, helping to prevent altitude sickness on the Choquequirao trek or, if you’re already experiencing it, to reduce the symptoms, allowing you to feel renewed and ready to face the challenges of the Choquequirao Trek.
Is it advisable to do a shorter trek before Choquequirao?
Absolutely. If you’re one of those travelers who has access to a small nearby hiking route, you could start conditioning your body in those areas. However, if you don’t have a close route or prefer something more low-key, you can do simple activities like walking, running, swimming, or biking.
These activities will help improve your physical condition, breathing, and endurance, which is ideal for tackling the challenges you’ll find on the Choquequirao Trek route—especially when dealing with altitude sickness on the Choquequirao trek.

Follow these recommendations—your symptoms will lessen or may not even appear.
Is it necessary to acclimatize before doing the Choquequirao trek?
Of course it is, and here’s something you should know: most travelers come from areas below 1,500 meters (4,921 feet) above sea level. What does that mean? That acclimatizing is mandatory before doing the Choquequirao Trek route, as it takes place above 2,000 meters (6,561 feet) and reaches elevations of over 3,000 meters (9,842 feet).
The change in altitude can trigger symptoms of altitude sickness, which is normal. In the best-case scenario, you might not experience them, but it’s very important to prevent their onset or avoid worsening your condition if they do occur. Altitude sickness on the Choquequirao trek is a common concern for many travelers, so having proper preventive measures is crucial to enjoy the journey safely.
Treating Altitude Sickness During the Trek
What should you do if you start feeling altitude sickness in Choquequirao?
It’s important to remember that not everyone adapts easily to high elevations, so if you feel unwell during the route, you must let your guide know immediately so they can take the necessary steps.
Altitude sickness is a common occurrence among travelers, which is why guides are trained to handle it, offering support that can include natural remedies, suitable foods, or if needed, generic medications. You might experience altitude sickness on the Choquequirao trek, but don’t worry, as guides are experienced in helping you overcome it.
No need to be anxious; that’s why having a travel agency that provides full support during your journey is crucial. Their help will be the most valuable thing you’ll need, even for unforeseen situations you’d least expect.

Acclimatization is a crucial step you shouldn’t skip to avoid the effects of altitude sickness.
What remedies can help relieve altitude sickness?
One of the most popular remedies among travelers visiting Cusco is drinking infusions of coca leaves and muña. These teas are excellent allies because their properties help significantly reduce the symptoms of altitude sickness, including altitude sickness on the Choquequirao trek.
Other travelers opt to visit pharmacies for pills like the famous “Sorochepill,” which also help alleviate these symptoms. Additionally, some choose to buy small portable oxygen canisters, allowing them to breathe more easily by providing the extra air their bodies need.
Note: If your symptoms are very severe, it’s important to consult a doctor, as they could worsen and lead to unwanted complications.
How do you know if altitude sickness symptoms are severe?
Traveler, although it’s unlikely, you should know that if during the route—or even before starting it—you experience much more intense symptoms than usual, such as difficulty breathing, it’s vital to take quick, preventive measures. In these cases, seeing a doctor will be key to receiving the necessary help and counteracting any setback, including symptoms of altitude sickness on the Choquequirao trek.
Take note! The remedies mentioned above are not always a definitive solution. Why? Remember that acclimatization capacity varies among travelers: some adapt quickly, others take more time, and there are those who simply don’t acclimatize well. Keep this in mind! Your well-being, as well as that of your travel companions, should always be a priority to fully enjoy the experience.

Symptoms are sometimes unavoidable; if they’re intense, it’s important to be seen by a physician.
Preventing Altitude Sickness in Choquequirao
How can you avoid altitude sickness on the Choquequirao trek?
Cusco is the starting point for many tourist activities and visits to important sites. Upon arrival, it’s important not to overexert yourself; you can walk slowly or rest at your hotel if you need to. Also, watch what you eat because the altitude can slow down digestion, which may worsen altitude sickness on the Choquequirao trek. Hence, it’s better to choose lighter meals and avoid fatty foods.
Remember to drink enough water during your first days. Many hotels offer coca and muña teas, which help prevent and relieve altitude sickness symptoms, especially if you plan to do activities like the altitude sickness on the Choquequirao trek.
How much acclimatization time is recommended before starting the Choquequirao trek?
Many travel agencies, such as Choquequirao Trek, advise their clients to allocate at least two days for the body to adapt to the altitude. This will allow you to enjoy your trip without any setbacks. Note! Don’t forget that your diet is crucial. Throughout this blog, I’ll share which foods to avoid and which ones are a must-have in your meals.
On the other hand, some travelers, wanting to make the most of their time, prefer to take small half-day tours. These activities don’t demand much physical effort and are an excellent way to acclimatize while discovering part of Cusco’s magic.

If you’ve already planned to do this trekking route, start exercising so you can tackle the challenges ahead.
Practical Tips for High-Altitude Treks
Which foods help prevent altitude sickness?
Your diet will play a very important role during your acclimatization days. It’s advisable to eat light meals such as soups, purées, and boiled foods. Keep this recommendation in mind, because the higher you go, the slower your digestion becomes.
What should you avoid? During the first few days, it’s important to steer clear of greasy foods, like any type of fried dishes. Also, don’t forget! Avoid alcoholic beverages, as alcohol dehydrates you and can intensify the symptoms of altitude sickness on the Choquequirao trek. If you add a hangover to that, you definitely won’t want to have a bad time, right?
Is water and hydration key to preventing altitude sickness?
Before continuing with this blog, you should remember that the higher the altitude, the faster your body loses water, which can lead to dehydration and increase the risk of suffering from altitude sickness on the Choquequirao trek.
Remember this! It’s very important to drink plenty of water to avoid dehydration and improve your oxygenation. This will help reduce or prevent altitude sickness symptoms. Take note! Drink water regularly, even if you don’t feel thirsty.

Don’t forget to drink water constantly; it will be crucial during your trip.
With the information we’ve provided, you now have the tools to tackle altitude sickness on your trek to Choquequirao. Plan well, listen to your body, and enjoy every step of this incredible journey. Don’t hesitate to apply these tips to make the most of your adventure!
