Learn How to Acclimate to High Altitude in Cusco and Enjoy Your 2026 Trip

Cusco, the ancient capital of the Inca Empire, is one of Peru’s most visited destinations. However, its location at 3,300 meters above sea level poses a challenge for many travelers: the altitude can cause altitude sickness or soroche, affecting energy levels and overall enjoyment of the trip.

This guide provides complete information on how to acclimate properly in Cusco, symptoms and prevention of altitude sickness, tips on nutrition and hydration, recommended activities, and practical advice to fully enjoy your 2026 tours, including Machu Picchu, Rainbow Mountain, and the Sacred Valley.

What is Altitude Sickness?

Altitude sickness, also known as soroche, occurs when the body does not adjust quickly to the reduced oxygen at high elevations. Common symptoms include:

• Headache.
• Nausea and vomiting.
• Fatigue and general weakness.
• Dizziness or vertigo.
• Difficulty sleeping.

These symptoms usually appear within 6 to 24 hours after reaching altitudes above 2,500 meters. In more severe cases, altitude sickness can cause pulmonary or cerebral edema, so it is important to follow preventive measures and know how to respond in emergencies.

How to Acclimate in Cusco

Gradual Arrival

One of the most effective ways to prevent altitude sickness is to allow your body to acclimate gradually.

• If arriving from Lima or the coast, avoid ascending above 3,000 meters on the first day.
• Rest for at least 24 to 48 hours upon arrival in Cusco before engaging in intense physical activities.
• Take short walks around the city to allow your body to adapt slowly to lower oxygen levels.

Constant Hydration

The dry air and high altitude increase the risk of dehydration, which can worsen symptoms of soroche.

• Drink water consistently, even if you are not thirsty.
• Avoid alcohol and caffeinated beverages during the first 24 hours.
• Drinking coca tea or local herbal infusions can improve circulation and relieve mild symptoms.

Light and Nutritious Meals

Nutrition also affects acclimation. Recommendations include:

• Eat easily digestible foods, avoiding heavy or greasy meals.
• Include fruits, vegetables, and complex carbohydrates to maintain energy.
• Avoid very salty foods that can affect blood pressure and fluid retention.

Adequate Rest

• Sleeping 7–9 hours per night helps regulate breathing and blood pressure.
• Slightly elevating the head while sleeping can improve nighttime breathing.
• Avoid strenuous activities right before bed.

Natural Remedies and Supplements

Some plants and supplements are traditionally used by locals for acclimation:

• Coca leaves: in tea or candy, help reduce dizziness and fatigue.
• Ginger: useful for nausea.
• Chancapiedra or muña tea: helps improve digestion and circulation.

Note: In cases of severe altitude sickness, it is recommended to seek medical attention in Cusco. Some tours include medical assistance for minor emergencies.

Recommended Activities for Acclimation

During the first 24 to 48 hours in Cusco, it is recommended to do light activities adapted to high altitude:

• Cusco City Tour: a gentle walk through plazas, temples, and markets.
• Cultural visits to Qorikancha or local museums.
• Short walks through historic neighborhoods like San Blas.

Avoid long excursions or strenuous hikes during the first days.

Tips for High Altitude Tours

Machu Picchu from Cusco

• Book in advance to choose optimal times and avoid crowds.
• The train ride helps slightly acclimate before reaching the citadel.
• Take stairs at a steady pace, avoiding running or rushing.

Rainbow Mountain

• This destination is over 5,000 meters high, so it is only recommended after spending a couple of days in Cusco.
• Consider the horseback option to reduce physical effort.
• Bring thermal clothing, water, and energy snacks to stay hydrated and nourished.

Sacred Valley and Combined Tours

• Always bring water and avoid heavy meals before full-day excursions.
• Take frequent breaks and follow guide recommendations.

Warning Signs of Altitude Sickness

• Severe difficulty breathing.
• Persistent dizziness or confusion.
• Severe headache that does not respond to painkillers.
• Continuous nausea or vomiting.

In these cases, it is recommended to descend to lower altitudes and seek immediate medical attention.

General Tips to Enjoy Your 2026 Trip

• Engage in moderate physical activity before your trip to improve stamina.
• Wear appropriate clothing and footwear for the Andean climate, which can change quickly.
• Plan itineraries with rest and acclimation days.
• Maintain a steady pace during walks and tours.
• Enjoy the landscape, culture, and local cuisine without overexerting yourself in the first days.

Conclusion

Acclimating to high altitude is key to fully enjoying your trip to Cusco in 2026. By following a gradual ascent, proper hydration, light meals, and adequate rest, travelers can minimize the effects of altitude sickness and enjoy iconic destinations such as Machu Picchu, Rainbow Mountain, and the Sacred Valley.
