Kevin LaheyIf you’re planning to hike the legendary Inca Trail to Machu Picchu, one of the biggest challenges you’ll face isn’t the distance, the steps, or even the rugged terrain—it’s the altitude. That’s why understanding the best Inca Trail tips for preventing altitude sickness is essential long before you take your first step on this ancient stone route.
Whether you’re a first-time high-altitude trekker or a seasoned hiker, this guide will walk you through everything you need to know to stay healthy, energetic, and confident throughout your journey.
Understanding Altitude Sickness Before the Inca Trail
What Altitude Sickness Really Is
Altitude sickness—also known as Acute Mountain Sickness (AMS)—happens when your body struggles to adapt to thin air at high elevations. As oxygen levels drop, symptoms like headaches, nausea, fatigue, and dizziness can kick in.
The Inca Trail reaches altitudes up to 4,215 m (13,828 ft) at Dead Woman’s Pass, making preparation critical.
Why Altitude Affects Inca Trail Hikers
Most travelers fly into Cusco (3,400 m / 11,154 ft), meaning your body suddenly jumps to a high altitude. Without time to adjust, the risk of AMS increases dramatically.

1. Acclimatize Properly Before Your Trek
Spend Time in Cusco First
One of the most effective Inca Trail tips for preventing altitude sickness is allowing your body time to adjust. Plan to spend 2–3 days in Cusco before the trek. Light walks around the old city or short hikes nearby can help ease your body into the altitude.
Slow Adjustment is Key
Your body needs time to increase red blood cell production. Don’t rush activities during your first 48 hours—rest, stay hydrated, and eat lightly.

2. Choose the Right Gear to Support Breathing & Comfort
Layers, Hydration Packs & Footwear
Having the right equipment—and knowing how to use it—matters more at altitude. A good layering system keeps your body temperature steady, which helps reduce stress on your system. Hydration packs make it easier to sip consistently, and proper footwear reduces physical strain.

3. Stay Hydrated the Smart Way
Water Intake Strategies
Dehydration is a fast track to altitude sickness. Aim to drink 2–3 liters per day, even if you don’t feel thirsty. Small, frequent sips work best.

Avoid Dehydrating Drinks
Skip alcohol, coffee, and sugary energy drinks during your acclimatization period. They dehydrate you faster and strain your system.
4. Fuel Your Body with High-Energy Foods
Balanced Trekking Meals
At altitude, your body burns through calories quickly. Eating high-energy, easy-to-digest foods helps you maintain energy and oxygen flow. Think bananas, nuts, soups, quinoa, oats, and energy bars.

What to Avoid Eating
Heavy, greasy, and salty foods make your body work harder. Stay light and balanced to reduce nausea risk.

5. Adopt a Slow & Stable Pace
Why “Slow is Fast” on the Inca Trail
Your lungs and heart are already working overtime. Rushing causes overexertion, one of the top triggers of AMS. Keep a consistent, relaxed pace and follow your guide’s rhythm.

6. Use Breathing Techniques for High Altitude
Deep Breathing Methods
Deep, controlled breathing improves oxygen absorption. Try inhaling through your nose for 4 seconds, exhaling slowly for 6 seconds. This supports endurance and reduces dizziness.
Oxygen Supplement Considerations
Some hikers use small oxygen canisters or altitude medication. Always consult a doctor before taking anything.

Night-Time Considerations
Altitude can make sleep difficult—avoid heavy meals and caffeine near bedtime.
10. Use Natural Remedies Like Coca Tea
Traditional Remedies
Coca tea or coca leaves are widely used in Peru. They naturally help with oxygenation, digestion, and energy levels. Most guides recommend it for a reason.
Hydration Benefits
Coca tea keeps you warm and hydrated, two major factors in altitude sickness prevention.
11. Listen to Your Body & Recognize Warning Signs
Early Symptoms
Watch for subtle signs like:
- headache
- loss of appetite
- dizziness
- fatigue
- nausea
When to Stop
If symptoms worsen, you must rest or descend. Pushing through can lead to severe complications.
