Cusco Altitude Acclimatization Guide

Last updated: August 10, 2025

Cusco sits at an elevation of approximately 3,400 meters (11,152 ft), and many visitors experience altitude sickness. Proper preparation is essential for a comfortable trip. This guide outlines two primary strategies for acclimatization.

Strategy 1: Acclimatize at a Lower Altitude

This is the most common recommendation for travelers. By starting at a lower elevation, your body can adjust more gradually.

• Go to the Sacred Valley: Upon arriving at Cusco's airport, travel directly to a town in the Sacred Valley, such as Urubamba or Ollantaytambo. The valley floor is at a lower elevation, around 2,900 meters (9,500 ft).
• Rest and Adjust: Spend your first 1-2 days in the Sacred Valley with minimal physical activity before traveling up to Cusco. This gives your body a gentler introduction to the altitude.

Strategy 2: Acclimatize in Cusco

If you cannot immediately travel to a lower altitude, you can still acclimatize safely by following these steps.

• Rest on Arrival: The most important step is to rest for the first 24-48 hours. Avoid any strenuous activity, including long walks or hiking.
• Move Slowly: Walk at a leisurely pace and avoid rushing. Cusco's steep streets can be more demanding than they appear.
• Stay Hydrated: Drink plenty of water to prevent dehydration, which can worsen symptoms. Avoid alcohol and caffeine.
• Eat Lightly: Choose small, easily digestible meals. Your body processes food more slowly at high altitudes, so avoid heavy, greasy foods.
• Local Remedies: Take advantage of local remedies such as coca tea, which is widely available. Local pharmacies also sell "Sorojchi Pills" that can help with symptoms.
• Medical Consultation: Consult with your doctor before your trip about prescription medications like Acetazolamide (Diamox) for altitude sickness prevention. Many hotels in Cusco also have oxygen tanks available if needed.
