What is the Inca Trail?

The Inca Trail is one of the most iconic trekking routes in the world, not only for its natural beauty but also for its profound historical and cultural value. This ancient Inca route was part of the vast network known as the Qhapaq Ñan, established by the Incas over 500 years ago, connecting the Andes with the Amazon rainforest and stretching over 30,000 kilometers (18,640 miles) throughout South America.

Today, the most famous section is the one that leads directly to the citadel of Machu Picchu, covering 43 kilometers (26.7 miles) of stunning landscapes. Along the way, hikers traverse towering mountains, pass through cloud forests, and explore ancient archaeological sites hidden among the vegetation. Completing this journey at Machu Picchu is the ultimate reward of an experience that combines nature with the legacy of an ancient civilization.

What is altitude sickness?

Altitude sickness, also known as soroche, is a reaction of the body to the lack of oxygen at high altitudes. When the body does not have enough time to adjust, it can manifest through various uncomfortable symptoms. While not everyone suffers from it, it is a fairly common condition when ascending rapidly above 2,500 meters (8,200 feet) from lower elevations. As you climb higher on a mountain, such as the Inca Trail, the air becomes less dense, meaning it contains less oxygen.

On the Inca Trail, you will reach one of the highest points: Warmiwañusqa Pass, also known as the “Dead Woman’s Pass,” at 4,215 meters (13,829 feet) above sea level. To put this into perspective, most people never experience this type of altitude in their daily lives, which means the body needs time to adapt. Fortunately, altitude sickness on the Inca Trail is usually mild and can be managed easily with the right precautions. It is important to remember that symptoms vary from person to person, and the fact that you have never experienced altitude sickness before does not guarantee you won’t feel it on the Inca Trail.

Altitude of the Inca Trail

Although the Inca Trail is not as high as more challenging routes like the Salkantay Trek or the Ausangate Trek, it presents significant altitude changes that are worth considering. The average altitude along the trail is 3,000 meters (9,843 feet) above sea level, but there are several notable points in terms of altitude.

The route begins at km 82 at around 2,700 meters (8,858 feet), gradually ascending until reaching its highest point at Warmiwañusqa Pass, also known as “Dead Woman’s Pass,” at 4,215 meters (13,828 feet). This is the highest point of the trek, where many people experience altitude sickness on the Inca Trail. After crossing this pass, the descent takes you to the Pacaymayo Valley at about 3,500 meters (11,482 feet).

The trail continues with another significant ascent, reaching the second highest point at Runkurakay Pass at 3,950 meters (12,959 feet). As you approach Machu Picchu, the altitude drops significantly, descending to approximately 2,400 meters (7,874 feet) upon arrival at the Inca Citadel.

The highest point of the Inca Trail might look intimidating but it's achievable.

Conquering the highest altitude of the Inca Trail is incredibly rewarding.

What are the symptoms of altitude sickness?

Altitude sickness symptoms can range from mild to more severe and typically appear within the first 6 to 24 hours of reaching high altitudes. Some of the most common symptoms include:

Keep these symptoms in mind to be sure you have altitude sickness.

Your hydration and nutrition are essential to avoid altitude sickness on the Inca Trail.

Who can suffer from altitude sickness?

Altitude sickness is more likely to affect those who are not accustomed to high altitudes, especially if they come from sea level or lower altitudes. Physical condition or previous mountain experience doesn’t guarantee immunity; acclimatization is key. Even someone in excellent physical shape can be more likely to suffer from altitude sickness on the Inca Trail if they ascend too quickly without allowing their body to adjust properly​.

On the other hand, those who live at high altitudes, such as people from mountain regions, are less likely to suffer from altitude sickness because their bodies are naturally adapted to lower oxygen levels. However, it’s important to remember that altitude sickness is unpredictable, and anyone who ascends too quickly has a higher chance of developing it​. The key is to acclimatize gradually.

Preparation before and during the Inca Trail

The Inca Trail is an incredible adventure, and with basic preparation, you’ll be ready to enjoy it without worry. Here are a few simple tips:

  1. Basic medical consultation: If you’re concerned about altitude sickness, ask your doctor for simple recommendations, such as using acetazolamide (Diamox).
  2. Stay fit: You don’t need to train like you’re climbing Everest, but doing regular hikes or climbing stairs before the trip will help you feel more comfortable during the trek.
  3. Acclimatize: Arrive in Cusco a couple of days before the trek. Take advantage of this time to explore the city while your body adjusts to the altitude. Two days are sufficient for most people.
  4. Stay hydrated: Drink water frequently. This is key to feeling good at higher altitudes. If you’re feeling adventurous, try coca leaf tea.
  5. Eat light: Eat light, healthy meals. Avoid heavy or greasy foods that may be hard to digest.
  6. Rest well: Sleeping well always helps. Rest before the trek so you’re full of energy.
