Why Altitude Matters on the Salkantay Trek
The Salkantay Trek altitude and acclimatization are two of the most important aspects to consider before starting this adventure. The trek reaches elevations over 4,600 meters (15,000 feet), where the air is thinner, and oxygen levels are significantly lower. Without proper acclimatization, hikers risk experiencing altitude sickness, which can affect performance and safety.
Key Altitudes Along the Salkantay Trek
The trek covers diverse terrain, from high mountain passes to lush cloud forests. Below are the approximate altitudes of the main sections:
Cusco: 3,400 m (11,150 ft) – Starting point, ideal for acclimatization.
Soraypampa (camp): 3,900 m (12,795 ft).
Humantay Lake: 4,200 m (13,780 ft).
Salkantay Pass (highest point): 4,650 m (15,255 ft).
Chaullay: 2,900 m (9,514 ft).
Santa Teresa: 1,550 m (5,085 ft).
Aguas Calientes: 2,040 m (6,690 ft).
Machu Picchu: 2,430 m (7,972 ft).
This variation makes the trek challenging but also rewarding, as hikers experience both high-altitude landscapes and subtropical climates.
Acclimatization Tips Before the Trek
To enjoy the trek and avoid altitude sickness, proper preparation is essential. Here are some recommendations:
Arrive in Cusco 2–3 days before the trek to allow your body to adjust.
Stay hydrated, drinking at least 2–3 liters of water daily.
Avoid alcohol and heavy meals before hiking days.
Drink coca tea or chew coca leaves, a traditional Andean remedy.
Climb gradually, allowing your body to adapt to higher elevations.
Symptoms of Altitude Sickness
Altitude sickness can occur when your body does not adapt quickly to reduced oxygen. Common symptoms include:
Headache
Nausea or vomiting
Dizziness
Fatigue
Shortness of breath
Most cases are mild and improve with rest, hydration, or medication. Severe cases are rare but require immediate descent and medical attention.
How Acclimatization Improves the Experience
When travelers follow acclimatization guidelines, they increase their chances of completing the trek comfortably. Hikers who adapt properly:
Have more energy for long days of walking.
Enjoy breathtaking views at the Salkantay Pass without health concerns.
Reduce risks of delays due to illness.
Fully experience the trek from high mountains to the lush jungle near Machu Picchu.
