Kevin LaheyIntroduction: Understanding Altitude Sickness on the Inca Trail
Trekking the Incan Stone Routes, particularly the renowned Inca Trail, offers an unforgettable adventure through the stunning landscapes of the Andes. However, with higher altitudes come greater challenges, including the risk of altitude sickness. Understanding what altitude sickness is and how to prevent it is essential for anyone planning to tackle these ancient stone paths. This guide will help you avoid the discomforts and risks associated with high-altitude trekking, ensuring you enjoy every step of the journey.
What is Altitude Sickness?
Altitude sickness, or Acute Mountain Sickness (AMS), occurs when your body struggles to adjust to higher altitudes where oxygen levels are lower. Symptoms typically include headaches, dizziness, nausea, and difficulty breathing.
Why is it Common on Incan Stone Routes?
The Incan Stone Routes, including the Inca Trail, reach heights of over 13,000 feet, which can significantly reduce oxygen levels. At these altitudes, trekkers are more susceptible to AMS. Proper preparation is critical to prevent this potentially debilitating condition.
1. Gradual Acclimatization: The Key to Success
One of the best ways to prevent altitude sickness is gradual acclimatization. By allowing your body time to adapt to increasing altitudes, you reduce the chances of experiencing AMS.
How Acclimatization Helps
Acclimatization boosts your body’s ability to absorb and circulate oxygen. The process allows your body to adjust to the thinner air, making it easier to function at high altitudes. Without acclimatization, your body may struggle to adjust to the reduced oxygen, leading to AMS.
Suggested Acclimatization Strategies
- Stay in Cusco or Sacred Valley: Both are at moderate altitudes and will give you time to acclimatize before starting your trek on the Inca Trail.
- Climb higher during the day and descend at night: This is a proven method that helps your body adjust without overstraining.

2. Stay Hydrated: The Power of Water
Hydration is crucial for your health, especially at high altitudes where dehydration is common. Drinking plenty of water helps your body perform optimally and minimizes the symptoms of AMS.
Importance of Water at High Altitudes
At higher elevations, the body loses water faster, and dehydration can intensify altitude sickness symptoms. Keeping hydrated helps you maintain your energy levels and supports proper circulation.
How Much Water Should You Drink?
You should aim to drink about 3-4 liters of water daily. However, don’t drink excessively in a short amount of time, as this can cause low sodium levels (hyponatremia). Spread your water intake throughout the day.

3. Consume the Right Foods: Fuel for the Journey
Proper nutrition is key to avoiding altitude sickness and maintaining energy during your trek. The right foods provide essential nutrients and help your body adjust to the demands of high altitudes.
Best Foods for High Altitudes
Opt for foods that are high in carbohydrates, such as whole grains and fruits. Carbs provide sustained energy, which is critical for long treks. Include protein and healthy fats to support muscle repair and keep you warm.
Altitude-Specific Nutritional Tips
Steer clear of overly greasy or heavy meals that could slow you down. Instead, focus on light, energy-dense foods like energy bars, nuts, and trail mix.

4. Take It Slow: The Pace Matters
The speed at which you trek is just as important as acclimatization. Going too fast at high altitudes can increase the likelihood of altitude sickness, so it’s important to maintain a manageable pace.
The Impact of Speed on Altitude Sickness
The faster you climb, the more oxygen your body needs, and this puts additional strain on your system. This can exacerbate AMS symptoms and lead to exhaustion, making it harder for your body to adapt.
How to Adjust Your Trekking Pace
Take regular breaks, walk slowly, and don’t feel pressured to keep up with others. Allow your body the time it needs to adjust. Keep an eye on your energy levels and adjust accordingly.

5. Rest Days: Don’t Rush the Climb
Resting is one of the simplest yet most effective ways to prevent altitude sickness. While it’s tempting to rush ahead, taking rest days allows your body the time it needs to acclimatize.
Why Rest Days Are Crucial
When trekking at high altitudes, your body needs recovery periods to adjust to the thinner air. Skipping rest days can lead to AMS and prevent your body from adjusting properly to the altitude.
Planning for Effective Rest Days
Include at least one or two rest days during your trek, particularly before reaching high-altitude campsites. On these days, relax, hydrate, and allow your body to acclimatize.

6. Medication: Know Your Options
There are medications available to help prevent and treat altitude sickness, which can provide an extra layer of protection, especially if you’re prone to AMS.
Common Medications for Altitude Sickness
Diamox (acetazolamide) is the most commonly used medication to speed up the acclimatization process. If you’re at risk, consult with your doctor about taking Diamox as a preventative measure.
When to Use Them and How to Get Them
Be sure to get the medication before your trip, as you’ll need a prescription. If symptoms persist, descending to lower altitudes is the most effective treatment.

7. Proper Gear and Clothing: Stay Comfortable and Safe
Proper gear ensures you’re physically prepared for the challenges of the Inca Trail, helping you maintain comfort and stay safe in varying weather conditions.
Gear for Altitude Comfort
Bring high-quality gear, including a sleeping bag suitable for cold temperatures, breathable clothes, and comfortable trekking shoes. Layer your clothing so you can adjust based on the weather.
Clothing Tips to Prevent Altitude Issues
Ensure you wear moisture-wicking clothes to prevent overheating and sweating. Also, pack layers to help regulate your body temperature as it fluctuates between warm days and chilly nights.

8. Monitor Your Symptoms: Early Detection Saves Lives
It’s essential to pay attention to your body’s signals during your trek. Monitoring your symptoms closely will help you detect altitude sickness early, giving you the best chance to act quickly.
Symptoms of Altitude Sickness to Watch For
Look out for signs such as headaches, dizziness, nausea, and shortness of breath. If these symptoms arise, take immediate action by resting, hydrating, and slowing your pace.
How to React to Symptoms Promptly
If symptoms worsen, consider descending to a lower altitude. It’s crucial to avoid pushing through severe symptoms, as this can be dangerous.

9. Listen to Your Body: Pay Attention to Warning Signs
Altitude sickness can worsen quickly if you don’t take proper precautions. It’s essential to listen to your body and trust your instincts.
Trusting Your Instincts in High Altitudes
If you’re feeling off or any symptoms seem to worsen, don’t ignore them. Turn back if necessary and seek medical assistance. Your safety should always be the priority.
When to Turn Back and Seek Help
If you experience severe symptoms such as confusion, loss of coordination, or extreme fatigue, it’s time to descend and get help.
10. Choose the Right Time for Your Trek
The time of year you choose to trek the Incan Stone Routes can significantly impact your risk of altitude sickness.
Season and Weather Considerations
The best months for trekking the Inca Trail are May to September, as the weather is generally dry. Trekking in the rainy season (November to March) can complicate acclimatization and increase the risk of altitude sickness.
How Timing Affects Altitude Sickness
Avoid trekking during extreme weather conditions, as the stress on your body can worsen symptoms. Plan accordingly to ensure the most favorable conditions for your trek.
