Is Altitude Sickness a Problem on Day Tours in Peru?

If you’re planning day tours from Cusco or visiting high-altitude destinations like Rainbow Mountain, Humantay Lake, or Lake Titicaca, you might be wondering:

«Will I get altitude sickness?»

The short answer? It’s possible — but manageable.

Here’s everything you need to know about altitude sickness (also called soroche in Peru), how it can affect you on day tours, and the best ways to prevent and treat it.

🧠 What Is Altitude Sickness?

Altitude sickness happens when your body struggles to adjust to lower oxygen levels at high elevations — usually above 2,500 m (8,200 ft).

Common symptoms:

• Headache
• Dizziness or nausea
• Fatigue
• Shortness of breath
• Trouble sleeping
• Loss of appetite

📍 How High Are Popular Day Tour Destinations?

• Cusco – 3,399 m / 11,152 ft
• Rainbow Mountain – 5,200 m / 17,060 ft
• Humantay Lake – 4,200 m / 13,779 ft
• Sacred Valley – 2,800 m / 9,186 ft
• Machu Picchu (Aguas Calientes) – 2,040 m / 6,692 ft

⏳ When Are You Most at Risk?

• Your first 1–2 days in Cusco are when you’re most vulnerable.
• Doing a high-altitude tour too soon can increase your chances of getting sick.
• Risk increases if you fly directly to Cusco from sea level without acclimatizing.

✅ How to Prevent Altitude Sickness

• Acclimate for 1–2 days in Cusco or the Sacred Valley before any high-altitude hike.
• Stay hydrated – drink plenty of water and avoid alcohol on your first days.
• Eat light meals – heavy meals can worsen nausea.
• Take it slow – avoid rushing or intense exercise at first.
• Drink coca tea or chew coca leaves – a traditional and effective remedy in Peru.
• Consider altitude medication – such as acetazolamide (Diamox), if recommended by your doctor.

💊 What If You Feel Sick on a Tour?

Most tour guides in Peru are trained to help and carry oxygen tanks for emergencies.

If symptoms appear:

• Tell your guide immediately.
• Take a break and rest — often the body adjusts with time.
• Descend to a lower altitude if symptoms worsen.

🧭 Pro Tips for Travelers

• If you’re planning to visit Rainbow Mountain or Humantay Lake, schedule them after a few days in Cusco.
• Visit the Sacred Valley or Machu Picchu first — both are at lower altitudes and good for acclimatization.
• Book with a reputable operator that prioritizes safety and has well-prepared guides.
