Quick Answer: When planning your cusco altitude sickness, to prevent altitude sickness (soroche) in Cusco (3,400 m / 11,152 ft), rest for the first 24 hours, drink 3 to 4 liters of water daily, sip traditional coca tea, eat light carbohydrate-rich meals, and avoid alcohol. If arriving directly from sea level, consider spending your first two nights in the Sacred Valley (2,800 m / 9,186 ft), which is 600 meters lower. Consult your physician about preventative medication like Acetazolamide (Diamox).

Cusco Altitude Sickness: Symptoms & Prevention Guide
When you fly from Lima (sea level) directly into Alejandro Velasco Astete Airport in Cusco at 3,400 meters (11,152 feet), atmospheric pressure drops by approximately one-third. While the percentage of oxygen in the air remains at 21%, each breath delivers fewer oxygen molecules to your lungs and bloodstream. Your body needs 48 to 72 hours to produce more red blood cells and adapt.
Mild symptoms of Acute Mountain Sickness (AMS), known locally as soroche, affect up to 70% of travelers. Common symptoms include a throbbing headache (especially behind the forehead), shortness of breath when climbing stairs, fatigue, mild dizziness, insomnia, and loss of appetite.
The 5 Golden Rules of Acclimatization
- The Sacred Valley Strategy: Instead of sleeping in Cusco on Day 1, take a private transfer directly from the airport down to the Sacred Valley (Pisac, Urubamba, or Ollantaytambo). At 2,800 meters, your body adapts much more comfortably.
- Rest on Day 1: Do not schedule demanding tours on your arrival day. Take a 2-hour nap, stroll leisurely through the historic center, and take deep, measured breaths.
- Hydrate Aggressively: High altitude causes rapid dehydration through increased respiration. Drink 3 to 4 liters of bottled water and electrolyte beverages daily.
- Embrace Coca & Muu00f1a Tea: Chewing dried coca leaves or drinking mate de coca is a 3,000-year-old Andean remedy that dilates blood vessels and alleviates headaches. Drink muu00f1a (Andean mint) tea to soothe digestion. Avoid coca tea after 5:00 PM as it contains natural stimulants that can disrupt sleep.
- Eat Light, Carb-Rich Foods: Digestion slows down significantly at high altitude. Eat soups, quinoa, rice, and lean proteins; avoid heavy, greasy meals and red meat for the first two days.
Medications & Emergency Oxygen in Cusco
If you have a history of altitude sensitivity, discuss Acetazolamide (Diamox) with your doctor before traveling. Taking 125 mg to 250 mg twice daily starting 24 hours before arriving in Cusco accelerates natural acclimatization. In Peru, local pharmacies (InkaFarma, Mifarma) sell over-the-counter Sorojchi Pills (a blend of aspirin, caffeine, and acetaminophen) which provide rapid relief from altitude headaches.
Virtually all reputable 3, 4, and 5-star hotels in Cusco maintain supplemental oxygen tanks in their lobbies or offer oxygen-enriched rooms upon request.
