Peru: A Country of Contrasts

Peru is a country full of Contrasts, not only in culture and landscapes but also in elevation. You can go from sea level in Lima to 3,400 meters (11,150 feet) in Cusco, and even higher at Lake Titicaca (3,800 m / 12,500 ft) within just a few days.
Among all these destinations, Cusco is where most travelers first feel the effects of high altitude. Knowing how to prepare and how your body reacts can transform your trip from challenging to truly enjoyable.

The Science Behind Altitude Sickness

At sea level, the air contains 21% oxygen, and higher atmospheric pressure helps your body absorb it easily.
In Cusco, the oxygen percentage remains the same, but the air pressure is lower. That means each breath provides fewer oxygen molecules, which can cause altitude sickness—locally known as soroche.
At 3,400 meters / 11,150 feet, travelers may experience symptoms such as:

Headache
Shortness of breath
Fatigue ir weakness
Dizziness or lightheadedness
Nausea or loss of appetite

The good news is that most travelers adapt within 24 – 48 hours. And remember: altitude sickness can affect anyone regardless of age, fitness level, or hiking experience.

Tips to Prevent and Manage Altitude Sickness in Cusco

At Belcheri Travel, we design itineraries that consider every detail of your comfort, including altitude. Here are our best recommendations:

Before Your Trip

Plan smartly: Spend your first night in the Sacred Valley (2,800 m / 9,150 ft) instead of Cusco. The lower altitude makes acclimatization easier.
Consult your doctor: Some travelers take prescribed medication like acetazolamide (Diamox) for prevention.

Upon Arrival in Cusco

Take it slow: Rest during your first day and avoid strenuous activities.
Stay hydrated: Drink plenty of water and limit alcohol or heavy meals.
Try local remedies: Traditional muña tea is a natural Andean remedy that helps with digestion and breathing.
Eat light: Soups, fruits, and vegetables are easier for your body to process at altitude.

If You Feel Unwell

Rest and give your body time.
Supplemental oxygen is available at many hotels and clinics.
If symptoms are severe (chest pain, extreme shortness of breath, or confusion), seek medical attention immediately.
