How to Prepare for Altitude in Cusco

23 de February de 2025 Peru

Cusco, the ancient capital of the Inca Empire, sits at an impressive 3,400 meters (11,152 feet) above sea level. Its charm, history, and proximity to Machu Picchu make it one of the most visited cities in South America. However, the high altitude can take travelers by surprise. Prepare Altitude Cusco properly before and during your stay will help you avoid discomfort and ensure you enjoy your time to the fullest.

Prepare Altitude Cusco: Understanding Altitude and Its Effects on the Body

Traveling to high-altitude destinations like Cusco, La Paz, or the Himalayas can be an unforgettable experience. However, the thinner air at higher elevations has a significant impact on the human body. Understanding how altitude works and its effects is key to staying safe and enjoying your journey.

What Is Altitude?

Altitude refers to how high a location is above sea level. At higher elevations, the air pressure decreases, meaning there is less oxygen available with each breath. While sea level offers about 21% oxygen concentration, the reduced air pressure at higher altitudes makes it feel as though there is less oxygen, which is what challenges the body.

Low altitude: 0–1,500 m (0–5,000 ft)
Moderate altitude: 1,500–2,500 m (5,000–8,200 ft)
High altitude: 2,500–3,500 m (8,200–11,500 ft)
Very high altitude: 3,500–5,500 m (11,500–18,000 ft)
Extreme altitude: above 5,500 m (18,000 ft)

Cusco, for example, sits at 3,400 m (11,152 ft), making it a high-altitude city.

How the Body Reacts to Altitude

When you ascend to higher altitudes, your body must adjust to reduced oxygen. Common reactions include:

Increased breathing rate – You may find yourself breathing faster to compensate for less oxygen.
Elevated heart rate – Your heart works harder to pump oxygen throughout your body.
Reduced physical performance – Tasks that feel easy at sea level may require more effort.
Changes in sleep – Some travelers experience difficulty sleeping at altitude.

Symptoms of Altitude Sickness

Altitude sickness, also known as acute mountain sickness (AMS), can affect anyone, regardless of fitness level or age. Symptoms may include:

Headache
Dizziness
Nausea or vomiting
Fatigue
Shortness of breath
Loss of appetite

These symptoms usually appear within 6–24 hours after arrival and can last for a few days as the body acclimatizes.

Acclimatization and Adaptation

The body gradually adapts to altitude through a process called acclimatization. Over several days, it produces more red blood cells, which carry oxygen more efficiently. That’s why experts recommend ascending gradually and giving yourself time to adjust before engaging in strenuous activities.

Long-term residents of high-altitude regions, like the Andes or Himalayas, adapt more permanently. Their bodies naturally develop more red blood cells and greater lung capacity to cope with lower oxygen levels.

Tips for Managing Altitude Effects

Ascend slowly whenever possible.
Stay hydrated and avoid alcohol or excessive caffeine.
Eat light, energy-rich meals.
Rest during the first 24–48 hours at high elevation.
Consider preventive medication if recommended by a doctor.
Seek medical help if severe symptoms occur, such as confusion, difficulty walking, or chest tightness.

Preparation Before Traveling to High Altitudes

High-altitude destinations such as Cusco in Peru, La Paz in Bolivia, or even the Himalayas attract travelers with their breathtaking landscapes and rich cultural experiences. However, visiting places above 2,500 meters (8,200 feet) requires special preparation to ensure a safe and enjoyable journey. Proper planning before your trip can minimize discomfort and help your body adjust more smoothly to thinner air.

Learn About Altitude and Its Challenges

At higher elevations, the air pressure decreases, which means less oxygen is available with each breath. This can lead to altitude sickness, with symptoms like headaches, fatigue, nausea, and dizziness. Understanding these risks in advance is the first step toward preparing your body and mind.

Schedule Time for Acclimatization

If possible, plan your itinerary to ascend gradually. Spending a day or two at a medium altitude—such as the Sacred Valley in Peru (2,800 m)—before moving higher gives your body valuable time to adapt. Avoid scheduling demanding hikes or tours immediately upon arrival at your highest destination.

Visit Your Doctor Before the Trip

Consult a healthcare professional before traveling to high altitudes, especially if you have heart, lung, or circulation conditions. Your doctor may prescribe acetazolamide (Diamox) or other preventive medication to reduce the risk of altitude sickness.

Train Your Body in Advance

Physical preparation helps your body handle the strain of high altitude. Activities such as cardio workouts, hiking, or jogging improve lung capacity and endurance. While no training can fully prevent altitude sickness, being fit will make the adjustment process easier.

Pack Smart for High Altitudes

The right gear makes a big difference. Essentials include:

Layered clothing – Weather at altitude changes quickly from hot sunshine to chilly evenings.
Sun protection – High-altitude sun is stronger, so bring sunglasses, sunscreen, and a hat.
Hydration tools – A reusable water bottle is key for staying hydrated.
Light snacks – Energy bars and easy-to-digest foods help maintain energy.

Prepare Your Diet and Habits

In the weeks leading up to your trip, focus on healthy eating and hydration. Limit alcohol and caffeine, as they can dehydrate you. Arriving well-rested and in good physical condition also helps your body adapt more effectively.

Mental Preparation Matters

High-altitude travel requires patience. Some discomfort is normal during the first few days. Preparing mentally by knowing what to expect will help you stay calm and give your body the time it needs to adjust.

Recommended Strategies During Your Stay in Cusco

Cusco, the gateway to Machu Picchu and the heart of the Inca Empire, offers travelers a magical blend of history, culture, and breathtaking landscapes. However, its high altitude (3,400 meters / 11,152 feet above sea level) and the intensity of activities can be challenging if you don’t prepare well. To make the most of your visit, here Prepare Altitude Cusco are some recommended strategies to follow during your stay in Cusco.

Take It Easy at First

When you arrive, resist the temptation to rush straight into strenuous sightseeing. Spend your first day walking at a gentle pace, exploring the main square (Plaza de Armas) or enjoying a relaxed meal. Giving your body time to adjust to the altitude will allow you to feel better and enjoy your adventures later.

Stay Hydrated and Try Local Remedies

Water is your best friend at high altitudes. Drink plenty throughout the day to prevent dehydration, which can worsen altitude symptoms. In addition, try traditional coca tea or coca candies, which locals use to alleviate mild effects of altitude. Herbal infusions such as muña tea are also soothing and beneficial.

Eat Light, Nutritious Meals

Heavy, greasy meals can be harder to digest at altitude. Choose soups, vegetables, fruits, and lean proteins to fuel your body without overloading your system. A popular choice among travelers is the local chicken soup (caldo de gallina), which is both nourishing and easy on the stomach.

Dress in Layers

Cusco’s weather can change dramatically in a single day. Mornings and evenings are often chilly, while midday sun can be surprisingly strong. Dressing in layers ensures you’re comfortable whether you’re exploring Inca ruins, visiting local markets, or strolling through cobblestone streets.

Pace Your Activities

Plan your itinerary strategically. Begin with lighter excursions, such as exploring Sacsayhuamán or Qorikancha, before moving on to more demanding adventures like hiking to Rainbow Mountain or visiting Machu Picchu. This gradual increase in activity helps your body adapt.

Use Sunscreen and Protect Yourself from the Sun

The sun is more intense at high altitudes. Always wear sunscreen, sunglasses, and a hat to avoid sunburn. Even on cloudy days, UV rays can be strong in Cusco.

Rest Well

Exploring Cusco can be exciting, but don’t underestimate the value of rest. Sleep is essential for recovery and acclimatization. Many hotels in Cusco also provide oxygen for guests if needed, which can help with symptoms of altitude sickness.

Respect Local Traditions

Cusco is not just a tourist hub; it’s a living city with deep traditions. Be mindful when visiting markets, taking photographs, or engaging with local communities. A respectful attitude enriches your travel experience and supports sustainable tourism.
