The Best Way to Acclimatize to Altitude in Peru

Before, During, and After Your Trek with Inca Land Adventures

Altitude acclimatization is the most important factor for enjoying high-altitude treks in Peru—especially routes like the Inca Trail, Salkantay, Ausangate, or Rainbow Mountain. Doing it correctly before and during your trek dramatically reduces the risk of altitude sickness and improves overall performance, sleep quality, and trekking enjoyment.

Understanding Altitude in Peru (Why Acclimatization Matters)

Most treks in the Andes take place between 3,000 m and 5,200 m (9,800–17,060 ft). Cusco itself sits at 3,399 m (11,152 ft), which means your body needs time to adapt to lower oxygen levels.

Without proper acclimatization, trekkers may experience:

• Headaches

• Fatigue

• Nausea

• Shortness of breath

Correct acclimatization allows your body to:

• Increase red blood cell production

• Improve oxygen efficiency

• Stabilize heart and breathing rates

✅ BEFORE YOU REACH HIGH ALTITUDE (MOST IMPORTANT STEP)

1. Arrive in Cusco Early (2–3 Days Minimum)

The most accurate and proven method is arriving in Cusco at least 48–72 hours before your trek. This gives your body time to begin natural adaptation.

2. Start Low, Go Slow

During your first days:

• Avoid strenuous activities

• Walk slowly

• Avoid alcohol and smoking

• Drink plenty of water

Recommended light acclimatization tours:

• Sacred Valley (Pisac, Ollantaytambo, Chinchero)

• Moray & Maras Salt Mines

These locations sit lower than Cusco, making them perfect for gradual adaptation.

3. Hydration & Nutrition

• Drink 2–3 liters of water daily

• Eat light, carb-rich meals

• Avoid heavy, greasy foods

Coca tea (traditional Andean remedy) may help relieve mild symptoms.

4. Follow a Gradual Itinerary

Inca Land Adventures designs trekking itineraries with strategic altitude progression, allowing your body to adjust naturally.

Key principles:

• Gradual elevation gain

• Built-in acclimatization days

• Professional guides trained in altitude safety

This is especially important for treks exceeding 4,000 meters.

5. Walk at Your Own Pace

Altitude is not about fitness—it’s about oxygen availability.

• Walk slowly

• Take frequent breaks

• Breathe deeply

Our guides encourage a “slow and steady” trekking rhythm, proven to reduce altitude symptoms.

6. Descend Slowly When Possible

Descending to lower elevations helps your body recover quickly. Most treks with Inca Land Adventures end at lower altitudes (Sacred Valley or Machu Picchu area), which naturally aids recovery.

7. Rest & Rehydrate

After your trek:

• Sleep well

• Continue hydrating

• Eat nutrient-rich meals

This helps stabilize oxygen levels and prevents post-trek fatigue.
