Acclimatization in the Atacama: how to prepare your body and mind for high altitude

Discover essential tips to enjoy the desert safely, with well-being and energy.

Traveling to the Atacama Desert is one of the most unforgettable experiences in South America. But before being amazed by colorful lagoons, volcanoes, and salt flats, it’s important to understand one key factor that makes all the difference: altitude.

San Pedro de Atacama sits at around 2,400 meters (7,900 ft) above sea level, and many tours — such as the Ruta de los Salares, El Tatio Geysers, Uyuni Salt Flat, and volcano climbs — reach altitudes between 4,000 and 4,800 meters (13,000–15,700 ft). This variation can affect your body, especially during the first 24 to 48 hours.The good news is that with a few simple precautions, you can enjoy every moment without discomfort and with complete safety.

🌬️ What happens to your body at high altitude

At high elevations, the air contains less oxygen. The body needs time to adapt, and during this process, mild symptoms such as headaches, fatigue, or drowsiness may appear.This phenomenon is known as altitude sickness (soroche) — common, but easily avoidable with proper acclimatization.These symptoms usually disappear as your body adjusts to the new environment, so the key is to respect your body’s rhythm.

🧘 How to prepare for altitude — body and mind

1. Arrive and restSpend your first 24 hours in San Pedro de Atacama doing light activities.Avoid high-altitude tours on your first day — give your body time to adjust.

2. Stay hydratedThe altitude and dry climate accelerate dehydration.Drink at least 2 liters of water per day and avoid alcohol during the first 48 hours.

3. Eat lightChoose meals that are low in fat and easy to digest.Fruits, vegetables, and soups help your body adapt and maintain energy.

4. Breathe deeply and walk slowlyPace is everything. Walk slowly and take frequent breaks to help your body adapt without overexertion.

5. Sleep wellRest is essential for acclimatization. Try to go to bed early and stay warm throughout the night.

6. Rely on local practicesAndean herbs are widely used in Chile and offer natural options to relieve mild altitude symptoms, while helping circulation and oxygenation.One example is Rica-rica (Acantholippia deserticola), a native plant of the Atacama Desert known for its digestive and stimulating properties.These traditional remedies can safely complement your acclimatization during the trip.
