Cusco sits at 3,400 meters above sea level, and the surrounding Andean peaks reach far higher. For many visitors arriving from sea level, some degree of altitude adjustment is inevitable. Understanding what to expect — and how to manage it — will help ensure your Soncco Adventures experience begins with energy and enthusiasm rather than headaches and nausea.
What Is Altitude Sickness?
Acute Mountain Sickness (AMS) occurs when the body does not have enough time to adapt to reduced oxygen levels at high altitude. Common symptoms include headache, fatigue, dizziness, loss of appetite, and nausea. Most cases are mild and resolve within 24-48 hours with proper rest and hydration. Severe cases are rare but require immediate descent to lower altitude.
Tips for Acclimatization
- Arrive a day early. Plan at least one full rest day in Cusco before any trekking or strenuous activity.
- Drink plenty of water. Staying hydrated helps your body adapt faster.
- Eat light meals. Heavy, rich food is harder to digest at altitude. Opt for soups, quinoa, and simple Andean dishes.
- Try coca tea. Widely available throughout Cusco, coca leaf tea is a traditional Andean remedy that many travelers find helpful.
- Avoid alcohol. Alcohol dehydrates and worsens altitude symptoms.
- Sleep low, explore high. If possible, sleep at a lower altitude and ascend during the day.
Medication
Acetazolamide (Diamox) is a prescription medication that can significantly reduce altitude sickness symptoms. Consult your doctor before travel. Many travelers also find over-the-counter ibuprofen helpful for altitude headaches.
