Altitude Sickness on the Choquequirao Trek

Trekking to Choquequirao is a once-in-a-lifetime adventure — remote landscapes, breathtaking views, and ancient Inca ruins that are still untouched by mass tourism.
But before you lace up your boots, there’s one important thing you should be prepared for: altitude sickness.

🌄 What Is Altitude Sickness?

Altitude sickness (also called «soroche» in Peru) happens when your body struggles to adjust to lower oxygen levels at high elevations. Symptoms often include:

• Headache
• Nausea or vomiting
• Dizziness
• Fatigue
• Shortness of breath

It usually appears above 2,500 m (8,202 ft) — and since much of the Choquequirao trek takes place between 1,500 and 3,100 m, it’s something to be aware of.

📍 What’s the Altitude Like on the Choquequirao Trek?

Here’s a rough breakdown of altitudes along the route:

• Capuliyoc (starting point) – 2,900 m (9,514 ft)
• Apurímac River (lowest point) – 1,500 m (4,921 ft)
• Marampata (camp before Choquequirao) – 2,900 m (9,514 ft)

Choquequirao ruins – approx. 3,050 m (10,007 ft)

The good news? While the trek is physically demanding due to steep descents and climbs, the altitude is moderate compared to places like Cusco 3,400 m (11,155 ft) or Rainbow Mountain 5,000 m (16,404 ft).

💡 How to Prevent Altitude Sickness

Here are a few simple ways to stay safe and feel your best on the trail:

1. Acclimatize in Cusco First
   Spend at least 2 days in Cusco or the Sacred Valley before starting the trek. It helps your body adjust gradually.
2. Hydrate Well
   Drink plenty of water — dehydration makes altitude symptoms worse.
3. Go Slow
   Avoid rushing. A steady pace helps your body adapt more easily.
4. Eat Light Meals
   Digesting heavy food takes more energy at altitude. Soups and carbs work well.
5. Coca Leaves or Coca Tea
   Locals have used coca for centuries to fight altitude symptoms. It’s natural and commonly offered on treks.
6. Consider Medication
   Ask your doctor about acetazolamide (Diamox) — a preventive medication for altitude sickness.

🤕 What If You Get Sick?

If you start to feel symptoms:

• Tell your guide immediately
• Rest and drink water
• Descend to a lower altitude if needed

Guides are trained to recognize and handle altitude sickness, so don’t hesitate to speak up.

✅ Final Thoughts

While the Choquequirao Trek isn’t as high as other Andean treks, it’s still important to prepare for altitude. Most travelers have mild symptoms or none at all, especially if they acclimatize properly.

With good preparation and a professional guide, you’ll be able to enjoy the journey fully — and focus on the incredible beauty and mystery of Choquequirao, rather than the challenges of the altitude.
